Quantum computers use qubits, which are based on quantum physics, allowing them to solve complex problems far faster than ...

After 30 months of fast-paced innovation in quantum algorithms, six research groups are hoping to hit paydirt. But there can be only one big winner—if there is a winner at all.

Charles Bennett and Gilles Brassard pioneered quantum information theory. Now they’ve been awarded the highest honor in computer science.

Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum ...

The errors that quantum computers make are holding the technology back. But recent progress in quantum error correction has ...

In today's edition of The Edward Snowden Files, The Washington Post reports that the National Security Agency, with a plan that sounds like something Lex Luthor cooked up, is racing to build a quantum ...

Two popular quantum computing algorithms for problems in chemistry may have very limited use even as quantum hardware ...
