The dream of quantum computing has always been exciting: What if we could build a machine working at the quantum level that could tackle complex calculations exponentially faster than a computer limited by classical physics? But despite seeing IBM, Google and others announce iterative quantum computing hardware, they're still not being used for any practical purposes. That might change with today's announcement from Microsoft and Quantinuum, who say they've developed the most error-free quantum computing system yet.

While classical computers and electronics rely on binary bits as their basic unit of information (they can be either on or off), quantum computers work with qubits, which can exist in a superposition of two states at the same time. The trouble with qubits is that they're prone to error, which is the main reason today's quantum computers (known as Noisy Intermediate Scale Quantum [NISQ] computers) are just used for research and experimentation.

Microsoft's solution was to group physical qubits into virtual qubits, which allows it to apply error diagnostics and correction without destroying them, and run it all over Quantinuum's hardware. The result was an error rate that was 800 times better than relying on physical qubits alone. Microsoft claims it was able to run more than 14,000 experiments without any errors.

According to Jason Zander, EVP of Microsoft's Strategic Missions and Technologies division, this achievement could finally bring us to "Level 2 Resilient" quantum computing, which would be reliable enough for practical applications.

"The task at hand for the entire quantum ecosystem is to increase the fidelity of qubits and enable fault-tolerant quantum computing so that we can use a quantum machine to unlock solutions to previously intractable problems," Zander, wrote in a blog post today. "In short, we need to transition to reliable logical qubits — created by combining multiple physical qubits together into logical ones to protect against noise and sustain a long (i.e., resilient) computation. ... By having high-quality hardware components and breakthrough error-handling capabilities designed for that machine, we can get better results than any individual component could give us."

Microsoft

Researchers will be able to get a taste of Microsoft's reliable quantum computing via Azure Quantum Elements in the next few months, where it will be available as a private preview. The goal is to push even further to Level 3 quantum supercomputing, which will theoretically be able to tackle incredibly complex issues like climate change and exotic drug research. It's unclear how long it'll take to actually reach that point, but for now, at least we're moving one step closer towards practical quantum computing.

The craze around Facebook Live might be a thing of the past, but Meta is still trying to make the platform video-friendly. The company has announced a new video player for uniformly displaying Reels, longer content and Live videos on the Facebook app. 

One of the biggest shifts is that all of Facebook's videos will now appear full-screen — even landscape-oriented ones. Videos will automatically play vertically, but you can now turn your phone on its side to watch most horizontal content across your entire device. 

Like many videos on TikTok, Facebook will now offer a slider at the bottom of the screen, letting you quickly move through the video. The update also brings some of the same features streamers like Netflix offer in their apps, such as the option to jump forward or backward by 10 seconds. Meta claims that you will now get "more relevant video recommendations" of all lengths appearing on the video tab and in your feed. The company will also be increasing the number of Reels shown on Facebook. 

The video player is rolling out now to Android and iOS users in the United States and Canada, with the new controls launching in the next few weeks. The entire update should be available globally in the coming months.

The Federal Communications Commission (FCC) plans to vote to restore net neutrality later this month. With Democrats finally holding an FCC majority in the final year of President Biden’s first term, the agency can fulfill a 2021 executive order from the President and bring back the Obama-era rules that the Trump administration’s FCC gutted in 2017.

The FCC plans to hold the vote during a meeting on April 25. Net neutrality treats broadband services as an essential resource under Title II of the Communications Act, giving the FCC greater authority to regulate the industry. It lets the agency prevent ISPs from anti-consumer behavior like unfair pricing, blocking or throttling content and providing pay-to-play “fast lanes” to internet access.

Democrats had to wait three years to enact Biden’s 2021 executive order to reinstate the net neutrality rules passed in 2015 by President Obama’s FCC. The confirmation process of Biden FCC nominee Gigi Sohn for telecommunications regulator played no small part. She withdrew her nomination in March 2023 following what she called “unrelenting, dishonest and cruel attacks.”

Republicans (and Democratic Senator Joe Manchin) opposed her confirmation through a lengthy 16-month process. During that period, telecom lobbying dollars flowed freely and Republicans cited past Sohn tweets critical of Fox News, along with vocal opposition from law enforcement, as justification for blocking the confirmation. Democrats finally regained an FCC majority with the swearing-in of Anna Gomez in late September, near the end of Biden’s third year in office.

“The pandemic proved once and for all that broadband is essential,” FCC Chairwoman Rosenworcel wrote in a press release. “After the prior administration abdicated authority over broadband services, the FCC has been handcuffed from acting to fully secure broadband networks, protect consumer data, and ensure the internet remains fast, open, and fair. A return to the FCC’s overwhelmingly popular and court-approved standard of net neutrality will allow the agency to serve once again as a strong consumer advocate of an open internet.”

You don't need to shell out a four-figure sum to find a great smartphone. In fact, you don't even need to spend half of that to snap up one that covers all of the basics and then some. At its regular price of $300, the OnePlus Nord N30 5G was already our pick for the best cheap phone around. It's currently on sale for $250 ($50) off, which makes it an even better deal. That's close to a record low price. The discount is part of a broader sale on OnePlus phones and earbuds.

The OnePlus Nord N30 5G offers great value however you slice it. The phone has a relatively zippy Snapdragon 695 5G processor, along with 8GB of RAM and 128GB of storage, which is expandable with a microSD card.

You'll get a 16MP front-facing camera and, on the rear, 108MP main and 2MP macro lenses. The 5,000mAh battery should last you a day of moderate use, while OnePlus says the 50W fast charging support will top it up from a one-percent charge to 80 percent in 30 minutes. The OnePlus Nord N30 5G also has a 6.7-inch, 120Hz IPS display that's great for gaming.

On the downside, there's no IP rating for dust or water resistance. And while the handset runs on Oxygen OS 13.1 (which is based on Android 13), OnePlus has only committed to bringing one major Android update to the N30, along with three years of security support. That's a pity for those looking for something that'll stay up to date for a few years without breaking the bank, but that level of Android support is typical for budget phones.

Stability AI just unveiled Stable Audio 2.0, an upgraded version of its music-generation platform. This system lets users create up to three minutes of audio via text prompt. That’s around the length of an actual song, so it'll also whip up an intro, a full chord progression and an outro.

First, the good news. Three minutes is huge. The previous version of the software maxed out at 90 seconds. Just imagine the fake birthday song you could make in the style of that one Rob Thomas/Santana track. Another boon? The tool is free and publicly available through the company’s website, so have at it.

It primarily works via text prompt, but there’s an option to upload an audio clip. The system will analyze the clip and produce something similar. All uploaded audio must be copyright-free, so this isn’t for the purposes of mimicking something that already exists. Rather, it could be useful for, say, humming a drum part or extending a 20 second clip into something longer.

Now, the bad news. This is still AI-generated music. It’s cool as a conversation piece and as an emblem of a possible future that’s great for tinkerers and bad for musicians, but that’s about it. The songs can actually sound nifty, at first, until the seams start showing. Then things get a bit creepy.

For instance, the system loves adding vocals, but not in any known human language. I guess it’s in whatever language that makes up the text in AI-generated images. The vocals sort of sound like actual people, and other times they sound Gregorian chanters filtered through outer space. It’s right smack dab in the middle of that uncanny valley. The Verge called the vocals “soulless and weird," comparing them to whale sounds. That tracks. 

Stable Audio 2.0 makes the same weird little mistakes that all of these systems make, no matter the output type. Parts can vanish into thin air, replaced with something else. Sometimes melodic elements will double out of nowhere, like an audio version of those extra fingers in AI-generated images.

There’s also the, well, boring-ness of it all. This is music in name only. Without a human connection, what’s the point? I listen to music to get inside the head of another person or group of people. There’s no head to get inside of here, despite constant proclamations that artificial general intelligence (AGI) is only months away.

So, this tech is an absolute gift for those making silly birthday videos or bank hold music. For everyone else? Shrug. One thing I can say from personal experience: It’s pretty fast. The system concocted an absolutely terrifying big band song about my cat in around a minute. 

The Hyundai Ioniq 5 N is one of the most extreme EVs you can buy at the moment. With over 600 horsepower delivered to all four wheels, plus a plethora of drive modes that help you do everything from circuit racing to drifting, it's a truly wild ride.

But it's about to get even wilder. Meet the new Hyundai Ioniq 5 N eN1 Cup car. This is a lightweight, caged, and big-winged version of Hyundai's rocket ship, tuned to such an extreme level that it isn't even road legal. Yes, this one's strictly for racing, and Hyundai is launching a focused racing series for the 5 N later this year.

Ahead of that, I headed to Korea to take it for a drive on a closed track. Inje Speedium is a tricky circuit with lots of elevation changes, and despite some inclement weather the Ioniq 5 N eN1 proved to be a masterful drive. And, at $100,000, for a track-ready machine, it's surprisingly value-priced. Watch the video above for the full story.

OnePlus is the latest company to hop on the AI train. The phone manufacturer is rolling out a new photo editing tool called AI Eraser, which lets users remove extraneous objects from their photos. The new feature will be available on a range of OnePlus smartphones, including the OnePlus 12 and 12R, OnePlus 11 and OnePlus Open.

To use the OnePlus AI Eraser, a person first has to highlight the parts of the image that need removing. These could be random people or a dirty trash can, but they can also be "imperfections" in the photo. Then, AI analyzes that area and creates a background that OnePlus claims will blend into the existing image. If it sounds familiar, it works basically the same as Adobe's Generative Fill and Google's Magic Eraser tools.  

However, this is a new venture for OnePlus, which uses its proprietary LLM to power the AI Eraser. "As OnePlus' first feature based on generative AI technology, AI Eraser represents the first step in our vision to liberate user creativity through AI and revolutionize the future of photo editing, empowering users to create remarkable photos with just a few touches," Kinder Liu, president and COO of OnePlus, said in a statement. "This year, we plan to introduce more AI features, and we look forward to their upcoming availability."

Fish swim, birds fly and streaming services increase their prices. That’s (mostly) the way of things. After maintaining the same pricing for Premium for a long time, Spotify looks set to increase it twice within a year in some countries.

According to Bloomberg, Spotify Premium will be around $1 more for an individual plan and about $2 costlier for family and duo plans by the end of April in a few markets, including the UK, Australia and Pakistan. The report suggests the US is in line for a similar increase later this year.

The higher fees are expected to offset the costs of audiobook offerings. Since October, Premium users in select markets have been able to listen to 15 hours of audiobooks per month at no extra cost. The company is said to have seen strong levels of audiobook consumption so far.

If users go over the 15-hour limit, they can pay for a 10-hour top up. It’s there that Spotify makes more money from its Premium audiobook library. The company also sells audiobooks on its web store.

Spotify has been chasing profitability since it went public in 2018 and to help it get there, it’s said to be preparing several more subscription tiers. One of those (a more expensive option) will reportedly offer high-fidelity audio, a feature the company has long been promising.

It may also introduce a basic tier that includes ad-free music and podcasts, with audiobooks being cut out. This plan is expected to cost $11 per month, the same as Spotify currently charges for Premium. As such, that $10 audiobook-only plan Spotify introduced in the US last month is starting to make more sense.

If you've yet to join the VR craze of the last few years, then now's a good time to do so. The 128GB Meta Quest 2 is currently available at Walmart for $199, down from $249 — a return to its record-low price. Not only is the sale enticing, but the deal comes with a $50 credit for the Meta Quest store. Amazon is offering the same 20 percent discount on the Meta Quest 2, but it doesn't include that extra credit. 

The Meta Quest 2 might not be the newest headset in its lineup, but it still has plenty of great features — and is our pick for 2024's best cheap VR headset. Plus, we gave it an 89 in our review back in 2020, when it was still called the Oculus Quest. 

The device is wireless, comfortable and much more affordable than the alternatives. Its field of vision is about 90 degrees and can change based on which face pads you use. The Meta Quest 2 also offers fast-switching LCDs, an 1832x1920 resolution and a 90Hz refresh rate. You can hook it up to your gaming PC or explore the many titles available on Meta's Quest store — especially with $50 to spend.

I remember begging my parents to get me a phone with a camera when the earliest ones were launched. The idea of taking photos wherever I went was new and appealing, but it’s since become less of a novelty and more of a daily habit. Yes, I’m one of those. I take pictures of everything — from beautiful meals and funny signs to gorgeous landscapes and plumes of smoke billowing in the distance.

If you grew up in the Nokia 3310 era like me, then you know how far we’ve come. Gone are the 2-megapixel embarrassments that we used to post to Friendster with glee. Now, many of us use the cameras on our phones to not only capture precious memories of our adventures and loved ones, but also to share our lives with the world.

I’m lucky enough that I have access to multiple phones thanks to my job, and at times would carry a second device with me on a day-trip just because I preferred its cameras. But most people don’t have that luxury. Chances are, if you’re reading this, a phone’s cameras may be of utmost importance to you. But you’ll still want to make sure the device you end up getting doesn’t fall flat in other ways. At Engadget, we test and review dozens of smartphones every year; our top picks below represent not only the best phone cameras available right now, but also the most well-rounded options out there.

What to look for when choosing a phone for its cameras

Before scrutinizing a phone’s camera array, you’ll want to take stock of your needs — what are you using it for? If your needs are fairly simple, like taking photos and videos of your new baby or pet, most modern smartphones will serve you well. Those who plan to shoot for audiences on TikTok, Instagram or YouTube should look for video-optimizing features like stabilization and high frame rate support (for slow-motion clips).

Most smartphones today have at least two cameras on the rear and one up front. Those that cost more than $700 usually come with three, including wide-angle, telephoto or macro lenses. We’ve also reached a point where the number of megapixels (MP) doesn’t really matter anymore — most flagship phones from Apple, Samsung and Google have sensors that are either 48MP or 50MP. You’ll even come across some touting resolutions of 108MP or 200MP, in pro-level devices like the Galaxy S24 Ultra.

Most people won’t need anything that sharp, and in general, smartphone makers combine the pixels to deliver pictures that are the equivalent of 12MP anyway. The benefits of pixel-binning are fairly minor in phone cameras, though, and you’ll usually need to blow up an image to fit a 27-inch monitor before you’ll see the slightest improvements.

In fact, smartphone cameras tend to be so limited in size that there’s often little room for variation across devices. They typically use sensors from the same manufacturers and have similar aperture sizes, lens lengths and fields of view. So while it might be worth considering the impact of sensor size on things like DSLRs or mirrorless cameras, on a smartphone those differences are minimal.

Sensor size and field of view

If you still want a bit of guidance on what to look for, here are some quick tips: By and large, the bigger the sensor the better, as this will allow more light and data to be captured. Not many phone makers will list the sensor size in spec lists, so you’ll have to dig around for this info. A larger aperture (usually indicated by a smaller number with an “f/” preceding a digit) is ideal for the same reason, and it also affects the level of depth of field (or background blur) that’s not added via software. Since portrait modes are available on most phones these days, though, a big aperture isn’t as necessary to achieve this effect.

When looking for a specific field of view on a wide-angle camera, know that the most common offering from companies like Samsung and Google is about 120 degrees. Finally, most premium phones like the iPhone 15 Pro Max and Galaxy S24 Ultra offer telephoto systems that go up to 5x optical zoom with software taking that to 20x or even 100x.

Processing and extra features

These features will likely perform at a similar quality across the board, and where you really see a difference is in the processing. Samsung traditionally renders pictures that are more saturated, while Google’s Pixel phones take photos that are more neutral and evenly exposed. iPhones have historically produced pictures with color profiles that seem more accurate, though in comparison to images from the other two, they can come off yellowish. However, that was mostly resolved after Apple introduced a feature in the iPhone 13 called Photographic Styles that lets you set a profile with customizable contrast levels and color temperature that would apply to every picture taken via the native camera app.

Pro users who want to manually edit their shots should see if the phone they’re considering can take images in RAW format. Those who want to shoot a lot of videos while on the move should look for stabilization features and a decent frame rate. Most of the phones we’ve tested at Engadget record at either 60 frames per second at 1080p or 30 fps at 4K. It’s worth checking to see what the front camera shoots at, too, since they’re not usually on par with their counterparts on the rear.

Finally, while the phone’s native editor is usually not a dealbreaker (since you can install a third-party app for better controls), it’s worth noting that the latest flagships from Samsung and Google all offer AI tools that make manipulating an image a lot easier. They also offer a lot of fun, useful extras, like erasing photobombers, moving objects around or making sure everyone in the shot has their eyes open.

How we test smartphone cameras

For the last few years, I’ve reviewed flagships from Google, Samsung and Apple, and each time, I do the same set of tests. I’m especially particular when testing their cameras, and usually take all the phones I’m comparing out on a day or weekend photo-taking trip. Any time I see a photo- or video-worthy moment, I whip out all the devices and record what I can, doing my best to keep all factors identical and maintain the same angle and framing across the board.

It isn’t always easy to perfectly replicate the shooting conditions for each camera, even if I have them out immediately after I put the last one away. Of course, having them on some sort of multi-mount rack would be the most scientific way, but that makes framing shots a lot harder and is not representative of most people’s real-world use. Also, just imagine me holding up a three-prong camera rack running after the poor panicked wildlife I’m trying to photograph. It’s just not practical.

For each device, I make sure to test all modes, like portrait, night and video, as well as all the lenses, including wide, telephoto and macro. When there are new or special features, I test them as well. Since different phone displays can affect how their pictures appear, I wanted to level the playing field: I upload all the material to Google Drive in full resolution so I can compare everything on the same large screen. Because the photos from today’s phones are of mostly the same quality, I usually have to zoom in very closely to see the differences. I also frequently get a coworker who’s a photo or video expert to look at the files and weigh in.
