使用λ系统的确定性光子-光子(SWAP)^{1/2}门

Deterministic photon-photon (SWAP)^{1/2} gate using a lambda system

Kazuki Koshino, Satoshi Ishizaka, Yasunobu Nakamura

摘要:

从理论上提出了一种利用三能级λ系统与单光子相互作用实现确定性光子-光子(SWAP)^{1/2}门的方法。lambda系统完全被动地用作光子量子比特的临时存储器; lambda系统的初始状态可以是任意的,并且在整个门操作中不需要辅助场的主动控制。这些独特的优点使得这种纠缠门适合于确定性和可扩展的量子计算。

英文摘要:

We theoretically present a method to realize a deterministic photon-photon (SWAP)^{1/2} gate using a three-level lambda system interacting with single photons in reflection geometry. The lambda system is used completely passively as a temporary memory for a photonic qubit; the initial state of the lambda system may be arbitrary, and active control by auxiliary fields is unnecessary throughout the gate operations. These distinct merits make this entangling gate suitable for deterministic and scalable quantum computation.
