An experiment with superconducting qubits opens the door to determining whether quantum devices could be less energetically ...

Quantum physicists have found a way to let a single qubit experience several different “journeys” through time at once, effectively bending a classic limit on how fast quantum systems are allowed to ...

Scientists have established a relationship between the complexity of a problem, and the physical processes of entanglement required to solve it. “Some mathematical problems are easy. Some mathematical ...

John Martinis has already revolutionised quantum computing twice. Now, he is working on another radical rethink of the technology that could deliver machines with unrivalled capabilities ...

The latest trends in software development from the Computer Weekly Application Developer Network. Sometimes classed as a Japanese startup, OptQC works with optical photonic technologies to develop a ...
