For humans, background noise is generally just a minor irritant. But for quantum computers, which are very sensitive, it can be a death knell for computations. And because “noise” for a quantum ...

Today is the era of noisy intermediate scale quantum (Nisq) computers. These can solve difficult problems, but they are said to be “noisy”, which means many physical qubits are required for every ...

For a while researchers thought they’d have to make do with noisy, error-prone systems, at least in the near term. That’s starting to change. In the past 20 years, hundreds of companies, including ...
