利用绝热转移制备腔态

Cavity state preparation using adiabatic transfer

Jonas Larson, Erika Andersson

摘要:

我们展示了如何为多个腔制备各种腔场态。所使用的状态准备技术与受激绝热拉曼通道或STIRAP的方法有关。腔模通过原子耦合,使得可以将任意的腔场态从一个腔转移到另一个腔,也可以制备非平凡的腔场态。特别地,我们展示了如何制备两个或多个腔的纠缠态,例如EPR态和W态,以及不同腔中相干态的各种纠缠叠加,包括薛定谔猫态。理论上的考虑得到了数值模拟的支持。

英文摘要:

We show how to prepare a variety of cavity field states for multiple cavities. The state preparation technique used is related to the method of stimulated adiabatic Raman passage or STIRAP. The cavity modes are coupled by atoms, making it possible to transfer an arbitrary cavity field state from one cavity to another, and also to prepare non-trivial cavity field states. In particular, we show how to prepare entangled states of two or more cavities, such as an EPR state and a W state, as well as various entangled superpositions of coherent states in different cavities, including Schrodinger cat states. The theoretical considerations are supported by numerical simulations.
