These Drums Beat in Perfect Synchrony Because They’re Quantumly Entangled

Physicists have built two tiny drums, each as large as a human hair is wide, and synchronized their vibrations exactly. They achieved this perfect unison of drums using a quantum mechanics phenomenon known as entanglement—and the drums could be useful for developing quantum computers. The two drums play together with a precision far beyond what…

How Microsoft’s Quantum Boast Went Bust

Microsoft is an outlier among the companies investing in quantum computing research. Unlike Google, IBM, or the handful of startups that have built noisy experimental prototypes out of superconducting circuits, ions, or photons, the company is trying to build a quantum computer by using objects known as Majorana particles—distinctive patterns of electrons in a tiny…

D-Wave’s New Quantum Computer Is Inscrutable and Open for Business

In theory, quantum computers should be faster at solving many problems compared to classical computers. But because their components are extremely delicate, existing quantum computers are still rudimentary and error-prone, and academic and industry researchers have yet to demonstrate a profitable use for them. In pursuit of commercial applications, companies have built incrementally more complex…

This New Quantum Processor Is Made of Light

Experts are still unclear on what material will make the best quantum computer, but one obscure candidate is gaining traction: infrared light. Earlier this month, quantum computing startup Xanadu, based in Toronto, Canada, put two of its so-called photonic quantum computers on the cloud—the first commercially available devices of their kind. Xanadu’s computers each consist…

A Meta-Theory of Physics Could Explain Life, the Universe, Computation, and More

You may think of physics as a way to explain the behaviors of things like black holes, colliding particles, falling apples, and quantum computers. But a small group physicists today is working on a theory that doesn’t just study individual phenomena; it’s an entirely new way to describe the universe itself. This theory might solve…

Department of Energy Rolls Out Plan for a Super-Secure Quantum Internet

Just a few days after the Trump administration announced it would be pouring $75 million to build three new national institutes dedicated to quantum computing, the Department of Energy took those plans one step further by rolling out its own blueprint for full-on quantum internet that could be up and running within the coming decade. According…

Devs Was an Utterly Bizarre Head Trip With a Surprisingly Beautiful Twist

Devs, the eight-part sci-fi miniseries from visionary director Alex Garland, has aired its final, head-spinning episode. With it, the mysterious final event surrounding a powerful prediction machine is finally revealed. But don’t expect Devs to serve up a tidy resolution to its spectacular exploration of what it means to exist—you’ll have to arrive there all…

Scientists Save Quantum States in a Diamond, a Tiny Step Toward a Quantum Internet

A newly created system can enhance quantum communications over longer distances—a small but crucial step toward a quantum internet. We’re in the early stages of a quantum boom, as researchers are attempting to augment our computing and communications capabilities with systems employing the weird mathematics that govern subatomic particles. One of the core goals of…

Searching for Dark Matter With Quantum Computers, One Blip of Light at a Time

For decades, scientists have struggled to define the stuff that comprises a quarter of the universe: dark matter. As experiments continue to turn up empty-handed, one team hopes to find dark matter by incorporating the laws that govern subatomic particles—quantum mechanics—with a nascent kind of technology called a quantum computer. It’s what’s brought Fermilab scientist…

Devs Review: Alex Garland’s Foray Into TV Is a Messy Trip Filled With Intriguing Concepts

Alex Garland has covered a lot of ground in his career—from authoring novels to screenwriting and directing. You might have noticed that he leans toward sci-fi; his directing debut, Ex Machina, dealt with artificial intelligence, and its follow-up, Annihilation, focused on alien life. Devs, his new television miniseries, continues in this sci-fi-adjacent vein, and while it…
