用于分布式量子网络的确定性单光子源

Deterministic Single-Photon Source for Distributed Quantum Networking

Axel Kuhn, Markus Hennrich, Gerhard Rempe

摘要:

一个三能级原子与一个高精细度光腔强耦合,根据需要发射出一系列单光子。光子是由两个原子基态之间的受激拉曼跃迁产生的,其中腔的真空场激励跃迁的一个分支,而激光脉冲确定性地驱动另一个分支。这个过程是么正的,因此本质上是可逆的,这对于量子通信和网络是必不可少的,并且光子应该适合于全光量子信息处理。

英文摘要:

A sequence of single photons is emitted on demand from a single three-level atom strongly coupled to a high-finesse optical cavity. The photons are generated by an adiabatically driven stimulated Raman transition between two atomic ground states, with the vacuum field of the cavity stimulating one branch of the transition, and laser pulses deterministically driving the other branch. This process is unitary and therefore intrinsically reversible, which is essential for quantum communication and networking, and the photons should be appropriate for all-optical quantum information processing.
