"With a laser pulse, you can tap that shell and make it ring like a bell," said physicist Till Rosenband of NIST, who built the existing quantum-logic clock.

“激光脉冲轻拍壳层产生了像铃声一样声音”，国家标准和技术研究所的物理学家Till Rosenband说，现有的量子逻辑时钟是由他开发的。

The key to both experiments is the quantum logic atomic clock, which USES the oscillation of a single aluminium ion to maintain precise timing.

两个实验的重点是量子铝原子钟，它利用单一铝离子的震荡来精准测量时间的流逝。

Quantum spatial positioning, clock synchronization and fiber optic communications become possible through researching the quantum entanglement characteristic between the simple two particles system.

通过研究最简单的两粒子体系之间的量子纠缠特性，使得量子远程定位、时钟同步和光纤通信成为可能。
