Federal agencies are now using quantum computing for logistics and security. Learn how infrastructure readiness enables ...

Quantum computers hold great promise for applications from drug discovery to cybersecurity. Yet figuring out what would give ...

The hardest idea in quantum mechanics to hold in a non-physicist’s head is that a thing can be in two states at once. Not ...

Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum computers can solve complex equations at staggeringly fast speeds that vastly ...

A team of physicists has demonstrated an 18-qubit quantum processor built on silicon that manages its own operation from ...

Quantum computing should be viewed as a powerful new tool for solving specific classes of exceptionally difficult problems.​ ...

Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

Quantum computers, such as this one shown at this year’s Mobile World Congress in Barcelona, Spain, could run programs that ...

The truth is less dramatic. There are three ways that AI and quantum computers overlap: first, in the problems they try to solve; second, in the way each can be used to build the other; and third, in ...

Zulfi Alam thinks his team doesn’t need to “prove” they engineered a new state of matter in their bid to reinvent computing. Science would disagree.
