Quantum mechanics controls reality on the smallest levels, but when scaled up, it’s often difficult to gauge how and why this realm matters in the practical world. That said, physicists will on occasion uncover an oddly practical use for spooky quantum phenomena, and when they do, technology is often the biggest beneficiary. Such is the case with a new finding pertaining to superradiance—an aspect of quantum mechanics that has traditionally led to more headaches than solutions.
Superradiance is a phenomenon in which a group of quantum particles collaborate to produce significantly stronger signals. It remains a serious nuisance for some physicists, as the phenomenon can quickly destabilize quantum systems—and, by extension, the operation of key quantum technologies.
However, researchers from Austria and Japan devised a novel method to exploit superradiance to produce powerful, long-lasting microwave signals. The team reported its results today in Nature Physics. The team notes that the discovery paves the way for technological advances in medicine, navigation, and quantum communication, according to a statement.
“This discovery changes how we think about the quantum world,” Kae Nemoto, study co-author and a physicist at the Okinawa Institute of Science and Technology (OIST) in Japan, said in the release. “That shift opens entirely new directions for quantum technologies.”
Questionable quantum teamwork
Physicist Robert Dicke proposed the idea of superradiance in 1954. Since then, physicists have identified and even utilized superradiance for a variety of systems, including semiconductors, experimental X-ray lasers, and even to explain the chaos near fast radio bursts and black holes.
Superradiance typically occurs when a group of excited atoms become entangled after interacting with a light source. That produces a short, yet intense, burst of light—emitting substantially more energy from the system than if a single particle were bouncing about by itself.
Order from chaos
For the experiment, researchers trapped tiny atomic defects inside a microwave cavity. The cavities contained tiny chambers with electron spins, which served as “miniature magnets” to represent different quantum states. Then, they observed how the system changed over time, applying the data to extensive computer simulations to better describe the physics at work.
The researchers noticed an odd “train of narrow, long-lived microwave pulses” that followed a superradiant burst, which they investigated further in their simulations. They found that, surprisingly, the “seemingly messy interactions between spins actually fuel the emission,” Wenzel Kersten, study lead author and a physicist at the Vienna University of Technology in Austria, said in the release.
“The system organizes itself, producing an extremely coherent microwave signal from the very disorder that usually destroys it,” Kersten added.
A reversal of concepts
Because superradiance releases so much energy, scientists have long suspected—and partly confirmed through experiments—that it creates technical challenges for quantum technology.
The new study supplants this view, suggesting instead that, with the right approach, the next generation of quantum technologies could benefit from the “very interactions once thought to disrupt quantum behavior,” Nemoto said.
For instance, the strong, self-sustained microwave signal could help operate ultra-precise clocks, communication links, and navigation systems. These signals are also highly sensitive to the slightest changes in magnetic or electric fields, a feature with potential applications for a myriad of devices.

![Sam Altman’s project World looks to scale its human verification empire. First stop: Tinder. | TechCrunch
At a trendy venue near the San Francisco pier, Sam Altman’s verification project World celebrated its next evolution and rapid expansion of its ambitions. And it’s starting with Tinder.
Tools for Humanity (TFH), the company behind the World project, announced Friday plans to integrate its verification tech into dating apps, event and concert ticketing systems, business organizations, email, and other arenas of public life.
“The world is getting close to very powerful AI, and this is doing a lot of wonderful things,” said Altman, speaking before a packed crowd at The Midway. “We are also heading to a world now where there’s going to be more stuff generated by AI than by humans,” he added. “I’m sure many of you [have had moments] where you’re like, ‘Am I interacting with an AI or a person, or how much of each, and how do I know?”
World (formerly Worldcoin) distinguishes itself from many of its ID verification peers by offering the ability to verify that a real, living human is using a digital service while still protecting that person’s anonymity. There is some complex cryptographic alchemy behind this (something called “zero-knowledge proof-based authentication”). The upshot: The company is creating what it calls “proof of human” tools, which are mechanisms that can verify human activity in a world rife with AI agents and bots.
Its chief tool for verification is a spherical digital reader called the Orb that scans a user’s eyes, converting their iris into a unique and anonymous cryptographic identifier (known as a verified World ID). This can then be used to access World’s services, although users can also access World’s app without one.
Altman kept his remarks brief on Friday (TFH’s co-founder and CEO, Alex Blania, was absent due to a last-minute hand surgery, Altman said). He then turned much of the presentation over to World’s chief product officer, Tiago Sada, and his team.
Sada explained that World was launching the newest version of its app (the last version was launched at an event in December), along with a plethora of new integrations for its technology.
World has been preparing, for some time, to deploy a verification service for dating apps — most notably, Tinder. Last year, Tinder launched a World ID pilot program in Japan. That pilot was apparently a success because World announced that Tinder would be launching its verification integration in global markets —including the U.S. The program integrates a World ID emblem into the profiles of users who have gone through its verification processes, thus authenticating them as a real person.

World is also courting the entertainment industry by launching a new feature called Concert Kit, where musical artists can reserve a certain number of concert tickets for World ID-verified humans. This is designed to ensure that fans are safe from scalpers who often use automated ticket-buying bots to scarf up seats. Concert Kit is compatible with major ticketing systems, including Ticketmaster and Eventbrite, and the company is promoting it via partnerships with 30 Seconds to Mars and Bruno Mars — both of whom plan to use it for their upcoming tours.
The event was full of many other announcements, including some aimed at businesses. A Zoom/World ID verification integration seeks to battle a supposed deepfake threat to business calls, and a Docusign partnership is designed to ensure signatures come from authentic users.
The company is also working on a number of features in anticipation of the Wild West of the agentic web, including one called “agent delegation,” in which a person can delegate their World ID to an agent to carry out online activities on their behalf. A partnership with authentication firm Okta has also created a system (currently in beta) that verifies that an agent is acting on behalf of a human. The system is set up so that a World ID can be tied to a specific agent and then, when the agent goes out into the web to operate on that person’s behalf, websites will know a verified person is behind the behavior, said Okta’s chief product officer, Gareth Davies, at the event.
So far, it’s been difficult for World to scale, due largely to the verification process itself. For much of the company’s history, to get its gold standard, you had to travel to one of its offices and have your eyeballs scanned by an Orb — a fairly inconvenient (not to mention weird) experience.

However, World has continually made moves to increase the ease and incentive structure for verification. In the past, it offered its crypto asset, Worldcoin, to some members who signed up and has distributed its Orbs into big retail chains so that users can verify themselves while they’re out shopping or getting a coffee. Now the company is announcing that it is significantly expanding its Orb saturation in New York, Los Angeles, and San Francisco. The company also promoted a service where interested users could have World bring an Orb to their location for remote verification.
In a conversation with TechCrunch, Sada also shared that World has attempted to solve the scaling problem by creating different tiers of verification. The highest tier is Orb verification, but below that, World has previously offered a mid-level tier, which uses an anonymized scan of an official government ID via the card’s NFC chip.
The company also introduced a low-level tier, or what Sada called “low friction”— meaning low effort, I guess, but also “low security” — which involves merely taking a selfie.
Selfie Check, which Sada’s team presented during the event, is designed to maintain user privacy.
“Selfie is private by design,” said Daniel Shorr, one of TFH’s executives, during the presentation. “That means that we maximize the local processing that’s happening on your device, on your phone, which means that your images are yours.”
Selfie verification obviously isn’t new, and fraudsters have long managed to spoof it. “Obviously, we do our best, and it’s like one of the best systems that you’ll see for this. But it has limits,” Sada told TechCrunch. Developers looking to integrate World’s services can choose from the three different verification tiers depending on the level of security that’s important to them, he noted.

![‘Project Hail Mary’ Won’t Be Coming to Streaming Any Time Soon
With all the excitement of movies to come this week thanks to CinemaCon, it was almost easy to forget that MGM provided an interesting update on one of our favorite movies of the year that’s already out: Project Hail Mary will head back to IMAX theaters this weekend for an extended theatrical run. But that extension also means one thing: you’ll have to wait to stream it at home for a good while longer. During its presentation at CinemaCon this week MGM confirmed that Phil Lord and Chris Miller’s sci-fi hit would make its return to IMAX screens for a limited-time, one-week run starting this weekend, a move that will likely inch Project Hail Mary ever closer to crossing the $600 million box office mark. But to put a finer point on the news, Miller took to Twitter yesterday to confirm specifically that the extension means you won’t be able to watch the film at home for the forseeable future.
We announced yesterday that MGM is extending the exclusive theatrical window for PROJECT HAIL MARY so it won’t be on streaming anytime soon. This is a movie that needs to be seen on a big screen – and w a full return to IMAX screens for 1 week only starting this weekend, make… https://t.co/suK8NYpgWM — Christopher Miller (@chrizmillr) April 16, 2026 “It won’t be on streaming any time soon,” Miller’s tweet reads in part. “This is a movie that needs to be seen on a big screen […] Bring friends and loved ones. It’s an experience to share with others.” Project Hail Mary launched on March 20, so it’s not too surprising that it’s not headed home just yet—it’s just shy of a month into its theatrical window, which has now been extended by at least another week with the return to IMAX. But as studios begin to try realigning towards more theatrical releases with longer exclusivity windows again (one of the lingering aftereffects of covid’s impact on movie theaters), we should probably expect some of the biggest films of the year and beyond to try and hold off of hitting streaming for as long as they can.
At least in Project Hail Mary‘s case, you can still go and see it somewhere, even if it’s not at home. Good things come to those who wait, but for now, you can head to a movie theater to get your fix again. Want more io9 news?
