我们演示了一个两比特的“受控-NOT”量子逻辑门的操作，它与简单的单比特操作一起，形成了一个用于量子计算的通用量子逻辑门。两个量子比特被存储在单个被囚禁原子的内部和外部自由度中，该原子首先被激光冷却到零点能量。退相干效应被确定为操作，并扩展系统到更多的量子比特的可能性似乎是有希望的。
We demonstrate the operation of a two-bit ''controlled-NOT'' quantum logic gate, which, in conjunction with simple single-bit operations, forms a universal quantum logic gate for quantum computation. The two quantum bits are stored in the internal and external degrees of freedom of a single trapped atom, which is first laser cooled to the zero-point energy. Decoherence effects are identified for the operation, and the possibility of extending the system to more qubits appears promising.
