The promise of so-called “quantum advantage” is simple. By harnessing the counterintuitive rules of quantum mechanics, ...

Qubits are the fundamental building blocks of quantum computers — and, when fitted into these machines — rely on the weird laws of quantum mechanics to process calculations in parallel.

A bit is like a coin sitting on a table. Let’s say heads represents a one, and tails represents a zero. When you look at a bit, it will be either a one or a zero. A qubit is more like a pool ball with ...

The researchers wait a bit, then flip the bystander qubit. This keeps its amplitude the same but inverts the phase, causing constructive interference to become destructive interference.

YORKTOWN HEIGHTS, N.Y. – A bolt from the maybe-future struck the technology community in late September. A paper by Google computer scientists appeared on a NASA website, claiming that an inn… ...
