Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform ...

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

Researchers from the US and the UK have studied the relationship between a quantum algorithm’s runtime and its resilience to noise, with unexpected results Optimising the design of a quantum algorithm ...

A few years back, Google made waves when it claimed that some of its hardware had achieved quantum supremacy, performing operations that would be effectively impossible to simulate on a classical ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the smallest scales, erasing information is not free, it consumes energy and ...
