光物质量子界面

Light-Matter Quantum Interface

K. Hammerer, K. Molmer, E. S. Polzik, J. I. Cirac

摘要:

我们提出了一个量子接口,它适用于通过原子样品的相位/偏振旋转之间的通行证的光脉冲的多次通行证。我们的建议不需要非经典光输入或对系统的测量,并且它预测光和原子的无条件纠缠仅从相干输入中快速增长。该接口可以实现量子信息处理中的许多任务,包括光与原子之间的隐形传态、光的量子存储以及原子和光变量的压缩。

英文摘要:

We propose a quantum interface which applies multiple passes of a pulse of light through an atomic sample with phase/polarization rotations in between the passes. Our proposal does not require nonclassical light input or measurements on the system, and it predicts rapidly growing unconditional entanglement of light and atoms from just coherent inputs. The proposed interface makes it possible to achieve a number of tasks within quantum information processing including teleportation between light and atoms, quantum memory for light and squeezing of atomic and light variables.
