利用超导量子相干装置制备纠缠态的方案
Generation of entangled state using superconducting quantum interference devices
摘要
本文提出用两个超导量子相干装置在一个单模大失谐腔中制备一个最大纠缠态的新方案,在这个方案里,腔场态处于虚激发,在超导量子相干装置和腔场之间没有信息传递,因此对腔的品质要求大大减低.
Abstract
We propose a new scheme to generate a maximally entangled state of twosuperconducting quantum interference devices with a nonresonant cavity. In this scheme, the cavity field is virtually excited, no quantum-information transfer exists between the SQUIDs system and the cavity field, thus the requirement on the quality factor of the cavity is greatly relaxed.
