decoheres

Definition

To lose the delicate quantum state necessary for computation, resulting in the breakdown of information and the introduction of errors.

Etymology

Derived from the Latin 'cohaerere' (to stick together), the prefix 'de-' signifies the separation or loss of that state. In physics, it specifically refers to a quantum system losing its coherent wave-like properties.

In the news

In the article, decoherence is described as the degradation that causes qubits to lose information quickly, which the new 'arm qubit' design aims to mitigate to enable longer computations.

Dual-purpose qubit design could speed operations while cutting quantum errors
