Quantum computers promise enormous computational power, but the nature of quantum states makes computation and data ...

Train delays can cascade into stalled commutes, economic losses, and vacation snags. Scheduling trains is computationally ...

In a milestone that brings quantum computing tangibly closer to large-scale practical use, scientists at Oxford University Physics have demonstrated the first instance of distributed quantum computing ...

The original version of this story appeared in Quanta Magazine. For computer scientists, solving problems is a bit like mountaineering. First they must choose a problem to solve—akin to identifying a ...

A search problem refers to the task of finding a solution within some space of possible options, and that space could be made up of discrete steps or continuously varying values. For example, solving ...

Quantum researchers have created a new algorithm that can reduce noise in qubits while they are working, and it does this in ...
