Researchers at Google have used their Willow quantum computer to demonstrate that "quantum contextuality" may be a crucial ...

But quantum supremacy is not a single, sweeping victory to be sought—a broad Rubicon to be crossed—but rather a drawn-out series of small duels. It will be established problem by problem, quantum ...

A quantum computer has demonstrated that it can solve a problem more efficiently than a conventional computer. This achievement comes from being able to unlock a vast memory resource that classical ...

Classical computing has operated as the fundamental power behind our digital world for many decades. Modern civilization relies on classical systems to operate smartphones and global financial ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

The promise of quantum computers appears to be that they will upend modern computing as we know it. With exceptional computational power, they’ll be performing feats unimaginable for any classical ...

Every online bank transfer, private message and Bitcoin transaction rests on the assumption that some math problems are ...

Photonic says it’s trying to build the world’s first highly scalable fault-tolerant quantum computer. It’s doing so with a ...

Quantum computing could represent the next secular growth trend for the tech sector. From 2025 to 2032, Fortune Business ...

Two of those early movers are IonQ ( IONQ +3.12%) and Rigetti Computing ( RGTI +1.91%). Both of these quantum stocks are volatile and richly valued relative to their near-term growth; however, which ...
