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 ...

Fortunately, low-noise replacement power supplies are readily available and not outrageously expensive - from $75 to $120 in computer stores or on the Web. Many use two or more small fans to maximize ...

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 ...
