通过辐射压力实现光学与宏观振动模之间的连续变量纠缠和量子态隐形传态

Continuous variable entanglement and quantum state teleportation between optical and macroscopic vibrational modes through radiation pressure

Stefano Pirandola, Stefano Mancini, David Vitali, Paolo Tombesi

摘要:

我们研究一个孤立的,完全反射,镜子照明的强激光脉冲。我们表明,由此产生的辐射压力有效地纠缠的反射镜振动模式与入射载波光束的两个反射光学边带模式。详细研究了所得到的三模态的纠缠,并证明了它对镜模温度的鲁棒性。然后,我们展示了如何利用这种连续变量纠缠将光学模式的未知量子态传送到镜子的振动模式上。

英文摘要:

We study an isolated, perfectly reflecting, mirror illuminated by an intense laser pulse. We show that the resulting radiation pressure efficiently entangles a mirror vibrational mode with the two reflected optical sideband modes of the incident carrier beam. The entanglement of the resulting three-mode state is studied in detail and it is shown to be robust against the mirror mode temperature. We then show how this continuous variable entanglement can be profitably used to teleport an unknown quantum state of an optical mode onto the vibrational mode of the mirror.
