Silicon Qubits Fail Because Their Atoms Sit Randomly
Researchers have traced the device-to-device swings in silicon spin-qubit valley splitting to random atomic-scale disorder inside the quantum well that...
Aquark Tests Cold-Atom Clocks With Royal Navy Radars
Aquark Technologies and its partners conducted a successful trial with the UK Royal Navy in June 2026, where two networked...
Can Quantum Save Democracy? Count the Voters First
“Can quantum save democracy” is the kind of headline that should trip an alarm. The claim behind it is concrete,...
Physicists Built a Controllable Quantum Fluid Inside a Chip
A Bose-Einstein condensate is sometimes called the fifth state of matter: cool a cloud of particles enough and they stop...
A Chinese Team Squeezed a 16-Qubit State Out of Just Four Photons
Photonic quantum computing runs on a resource that’s maddeningly hard to make: entangled photons. Photon sources are inefficient, and the...
Pasqal Put the Lasers That Trap Its Atoms Onto a Chip
A neutral-atom quantum computer holds each of its qubits in a cage made of light. Focused laser beams called optical...
Physicists Turned Quantum Computing’s Worst Enemy Into a Way to Make Entanglement
Ask anyone building a quantum machine what they fear most and the answer is dissipation: the slow leak of energy...
Scientists Made Entangled Photons With Sunlight, No Laser Needed
For as long as anyone has built quantum light, the rule was simple: to make a pair of entangled photons,...
Spooky Signals Survived a Trip Through Maryland’s Messiest Fiber
Entanglement is the strangest resource in physics and one of the most delicate. Two photons can share a single quantum...
Quantum Source’s Plan: Photons Carry the Information, Atoms Do the Linking
Every approach to a useful quantum computer is trying to clear the same bar: error correction good enough to run...
