Recent tests show that quantum computers made by D-Wave systems should solve some problems faster than ordinary computers. Researchers have begun to map out exactly which queries might benefit from these quantum machines.
In the drive to safeguard data from future quantum computers, cryptographers have stumbled upon a thin red line between security and efficiency.
A quantum computing pioneer explains why the near future of quantum computation may lie in simulators, not general-purpose quantum machines.
A scientist at Bell Labs has started construction of a topological qubit, which could be the building block of a robust, scalable quantum computer.
The nature of computing has changed dramatically over the last decade, and more innovation is needed to weather the gathering data storm.
How do you know if a quantum computer is doing what it claims? A new protocol offers a possible solution and a boost to quantum cryptography.
An interview with the Berkeley chemist K. Birgitta Whaley on the promise and challenge of translating quantum biology into practical quantum devices.
Computer scientists are finding that “thinking quantumly” can lead to new insights into long-standing problems in classical computer science, mathematics and cryptography, regardless of whether quantum computers ever materialize.
