基于超导共面波导的快速原子-光子纠缠门

Fast atom-photon entangling gates with a superconducting coplanar waveguide

Xiao-Feng Shi

摘要:

超导共面波导中原子与微波光子之间的纠缠可以实现量子混合器件以及静态和飞行量子比特的接口。本文研究了在超临界阱附近囚禁的中性原子和超临界阱中的微波模之间的一步控制Z ~(C $_{\text{Z}}$)门,它是[J. D. Pritchard等人,A 89,010301(R)(2014)]。门协议是简单的,并且需要一个激光脉冲来激发中性原子的基态和里德伯态之间的跃迁。

英文摘要:

Entanglement between atoms and microwave photons in a superconducting coplanar waveguide~(SCW) can enable hybrid quantum devices and interface static and flying qubits. We study a one-step controlled-Z~(C$_{\text{Z}}$) gate between a neutral atom trapped near a SCW and a microwave mode in the SCW, which is an extension of the gate proposed in [J. D. Pritchard, et.al., Phys. Rev. A 89, 010301(R) (2014)]. The gate protocol is simple and requires one laser pulse for exciting a transition between the ground and Rydberg states of the neutral atom.
