In the simplest case, one obtains a system with two energy states, a so-called quantum bit or qubit.

在最简单的情况下，一个系统有两个能量状态，即所谓的量子比特或昆比特。

In a conventional computer, a bit can represent either 1 or 0 at any time. Thanks to the quirks of quantum mechanics, the equivalent in a quantum computer, a qubit, can represent both values at once.

在一个传统计算机中，任何时刻一个比特被表示为1或0.由于量子力学的奇怪结果，等价的情形在一个量子计算机中，一个量子比特能够被表示为任意值的叠加。
