利用远距离量子纠缠实现波长隐形传态

Wavelength Teleportation via Distant Quantum Entanglement

M. S. Shahriar, P. Pradhan, V. Gopal, G. Pati, G. C. Cardoso

摘要:

最近,我们从理论上[1]和实验上[2]证明了如何通过测量由电磁场激发的二能级原子系统的两个态中的任何一个的布居来确定电磁场的相位,通过所谓的布洛赫-西格特振荡,该振荡由同向和反向旋转激发之间的干涉引起。在这里,我们将展示如何在不传输任何定时信号的情况下创建简并纠缠,可以用来传送此相位信息。这种相位隐形传态过程可以应用于实现波长隐形传态,波长隐形传态又可以用于远程振荡器的频率锁定。

英文摘要:

Recently, we have shown theoretically [1] as well as experimentally [2] how the phase of an electromagnetic field can be determined by measuring the population of either of the two states of a two-level atomic system excited by this field, via the so-called Bloch-Siegert oscillation resulting from the interference between the co- and counter-rotating excitations. Here, we show how a degenerate entanglement, created without transmitting any timing signal, can be used to teleport this phase information. This phase-teleportation process may be applied to achieve wavelength teleportation, which in turn may be used for frequency-locking of remote oscillators.
