This tiny chip could change the future of quantum computing

A new microchip-sized device could dramatically accelerate the future of quantum computing. It controls laser frequencies with extreme precision while using far less power than today’s bulky systems. Crucially, it’s made with standard chip manufacturing, meaning it can be mass-produced instead of custom-built. This opens the door to quantum machines far larger and more powerful […] more…

This strange magnetism could power tomorrow’s AI

Scientists in Japan have confirmed that ultra-thin films of ruthenium dioxide belong to a newly recognized and powerful class of magnetic materials called altermagnets.

“Purifying” photons: Scientists found a way to clean light itself

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University of Iowa researchers found that unwanted photons produced by lasers can be canceled out by carefully tuning the light itself. The result is a much purer stream of single photons, a key requirement for […] more…

Scientists prove “impossible” Earth-to-space quantum link is feasible

Researchers have shown that quantum signals can be sent from Earth up to satellites, not just down from space as previously believed. This breakthrough could make global quantum networks far more powerful, affordable, and practical. more…

Scientists just found a way to tell if quantum computers are wrong

Easy to integrate into existing quantum chips, the approach could make processors like Google’s vastly more powerful. more…

Physicists reveal a new quantum state where electrons run wild

Electrons can freeze into strange geometric crystals and then melt back into liquid-like motion under the right quantum conditions. Researchers identified how to tune these transitions and even discovered a bizarre “pinball” state where some electrons stay locked in place while others dart around freely. Their simulations help explain how these phases form and how […] more…

A radical upgrade pushes quantum links 200x farther

Scientists have developed a new way to build rare-earth crystals that boosts quantum coherence to tens of milliseconds. This leap could extend quantum communication distances from city blocks to entire continents. The method uses atom-by-atom construction for unprecedented material purity. more…
