Quantum computers have passed a mathematically proven test that no classical computer can ever pass, demonstrating an unconditional quantum advantage for the first time.

DOE, Oak Ridge produce ultra-enriched silane for quantum computers. Silicon-28, germanium-74 isotopes boost qubit coherence, securing domestic quantum supply chain.

Japan switched on its first full-stack neutral-atom quantum computer. Shunkai starts with 50 qubits, plans 500, and targets 10,000 by 2031.

Breuckmann, Golowich and Vazirani prove quantum circuits can survive an adversary corrupting an almost-linear number of qudits at every time step.

Two Nature studies unveiled silicon quantum processors using spin-shuttling and CMOS control, bringing practical quantum computing closer than ever before.

Google's Willow quantum chip has reignited concerns about cryptocurrency security. Here's what quantum computing means for Bitcoin's future. How soon will quantum threats become real?
