A Special Diamond Is the Key to a Fully Open Source Quantum Sensor

A Special Diamond Is the Key to a Fully Open Source Quantum Sensor

Tech-news , , , ,

Quantum computing is either a distant dream or an imminent reality depending on who you ask. And while much of this year’s Quantum Village at the Defcon security conference in Las Vegas is focused on emerging research and threat analysis, village cofounders Victoria Kumaran and Mark Carney are also working to make a currently available quantum technology more accessible to hackers and anyone else.

In a main-stage Defcon talk on Saturday, the pair will present an open source and affordable quantum sensor that can serve a variety of uses, from medical technologies to GPS alternatives. And it’s all powered by a special yet affordable diamond with particular atomic properties. The first generation design could be assembled for about $120 to $160 depending on suppliers and shipping times. The second version that Kumaran and Carney are presenting this weekend can be built for even less, and the pair says that they will release a third version this fall based on community testing and input that they hope will cost just $50 to build.

Quantum sensors detect extremely slight variations in magnetic and electrical fields, enabling ultra-precise measurements. Atomic clocks that keep nearly perfect time, for example, are quantum sensors that have been in use for decades. For researchers and enthusiasts interested in learning more about quantum sensing, though, the barrier to entry has been quite high. So the Quantum Village’s relatively affordable, open source “Uncut Gem” project creates a real opportunity for more people to build their own quantum sensors and explore the technology.

“You can do things you wouldn’t have been able to do before, like using quantum sensors to start building portable MRI-style devices that can be used in all different countries,” Kumaran told WIRED ahead of their presentation. “These are diamonds with defects, synthetic diamonds that are the cheapest off-cuts you can get. I think there’s something a bit poetic that synthetic diamonds have this utility.”

Most of the components needed for the quantum sensor are simple off-the-shelf computing parts, but the diamond needs to be what’s known as a “nitrogen-vacancy diamond.” Its special molecular properties are thanks to the presence of nitrogen atoms that replace some carbon atoms in the diamond’s atomic structure.

In addition to potential medical applications, quantum sensors can be used in alternative navigation technologies that track electromagnetic wave interference. Such tools could be used as local alternatives to GPS in the case of global system failures or targeted jamming. US Space Force is currently testing what a release called the “highest-performing quantum inertial sensor ever tested in space.”

For the vast majority of people who don’t have access to the world’s highest performing quantum sensors, though, the Uncut Gem project represents an opportunity to democratize and expand quantum sensing technology. The project joins others in different fields of hacking that have been geared toward low-cost, accessible designs and components.

Independent researcher Davide Gessa has been testing the Uncut Gem schematics and code.

Every time I’ve written about Meta’s AI-enabled glasses, I invariably get asked these questions: Why do you even want these? Why do you want smart glasses that can play music or misidentify native flora in a weirdly cheery voice? I am a lifelong Ray-Ban Wayfarer wearer, and I’m also WIRED’s resident Meta wearer. I grab a pair of Meta glasses whenever I leave the house because I like being able to use one device instead of two or three on a walk. With Meta glasses, I can wear sunglasses and workout headphones in one!

Meta sold more than 7 million pairs in 2025. Take a look at any major outdoor or sporting event, and you’ll see more than a few people wearing these to record snippets for Instagram or TikTok. Meta’s partnership with EssilorLuxottica has made smart glasses accessible, stylish, and useful and is undoubtedly the reason why Google, and now Apple, are trying to horn in on the market. After the notable flop that is the Apple Vision Pro, Apple is recalibrating its face-wearable strategy, moving away from augmented reality (AR) toward simpler, display-less, and hopefully good-looking glasses.

That’s not to say that you shouldn’t be careful how you use these glasses. Meta doesn’t have the greatest track record on privacy, and the company has continued to push forward with policies that are questionable at best. Even if you’re not concerned that face recognition will allow Meta to target immigrants or enable stalkers to find their victims, at the very least, people really do not like the idea that you could start recording them at any moment.

Probably the biggest hurdle to wearing Meta glasses is that even doing so seems like a gross violation of the social contract. After all, these are Mark Zuckerberg’s “pervert glasses.” When I pop these on my head, I’ve had friends (and my spouse) recoil and say, “I have apps to warn me away from people like you.” The best part, though, is that Oakley and Ray-Ban already make really great sunglasses. Even if the battery runs out or you don’t use Meta AI at all, these are stellar at shading your eyes from the sun.

Anyway, if you decide to try them, here’s what you should get. If you do chicken out, check out our buying guides to the Best Smart Glasses or the Best Workout Headphones for more.

Meta Glasses (Gen 2)

Last year, Meta upgraded the original Meta Ray-Ban Wayfarers that became a smash hit. These are Meta’s entry-level glasses, and they come in a variety of lens styles. You can order them with clear lenses, prescription lenses, transition lenses, or the OG sunglass lenses, as well as in a variety of fits, including standard, large, or high-bridge frames. Improvements to this generation include an upgrade to a 12-MP camera and up to eight hours of battery life; writer Boone Ashworth’s testing clocked in at five to six hours.

After days of almost (and complete) darkness, the Moon is finally starting to reappear. We’re currently in the Waxing Crescent phase of the lunar cycle, which means each night until the Full Moon we’ll see it get more illuminated from the right side.

What is today’s Moon phase?

As of Sunday, April 19, the Moon phase is Waxing Crescent. Tonight, 5% of the moon will be lit up, according to NASA’s Daily Moon Guide.

Despite more of it now being illuminated, the percentage of surface is still too little to be able to spot any surface details. Check again tomorrow.

When is the next Full Moon?

The next Full Moon is predicted to take place on May 1, the first of two in May.

What are Moon phases?

NASA states that the Moon takes about 29.5 days to orbit Earth, during which it passes through eight distinct phases. We always see the same side of the Moon, but the amount of sunlight reflecting off it changes as it moves along its orbit, creating the familiar pattern of full, partial, and crescent shapes. We call these the lunar phases, and there are eight in total:

New Moon – The Moon is between Earth and the sun, so the side we see is dark (in other words, it’s invisible to the eye).

Waxing Crescent – A small sliver of light appears on the right side (Northern Hemisphere).

First Quarter – Half of the Moon is lit on the right side. It looks like a half-Moon.

Waxing Gibbous – More than half is lit up, but it’s not quite full yet.

Full Moon – The whole face of the Moon is illuminated and fully visible.

Waning Gibbous – The Moon starts losing light on the right side. (Northern Hemisphere)

Third Quarter (or Last Quarter) – Another half-Moon, but now the left side is lit.

Waning Crescent – A thin sliver of light remains on the left side before going dark again.

According to Nikkei Asia, even as suppliers ramp up DRAM production, manufacturers are only expected to meet 60 percent of demand by the end of 2027. SK Group chairman has even said that shortages could last until 2030.

The world’s largest memory makers — Samsung, SK Hynix, and Micron — are all working to add new fabrication capacity, but almost none of it will be online until at least 2027, if not 2028. SK opened a fab in Cheongju in February, but that is the only increase in production among the three for 2026.

Nikkei says that production would need to increase by 12 percent a year in 2026 and 2027 to meet demand. But according to Counterpoint Research, an increase of only 7.5 percent is planned.

The new facilities will primarily focus on producing high-bandwidth memory (HBM), which is used in AI data centers. With the companies already prioritizing HBM over general-purpose DRAM used in computers and phones, it’s not clear how much these new fabs will help alleviate the price crunch facing consumer electronics. Everything from phones and laptops, to VR headsets and gaming handhelds have seen price increases due to the RAM shortage.
