摘要

我们提出了一种利用超导量子比特系统耦合到空腔来实现3量子位量子控相门的方法。该方案不需要调整量子位水平间距或相同的量子位-腔耦合常数。此外,由于只应用了谐振相互作用,栅极可以在10纳秒内快速完成。这个提议是相当普遍的,可以应用于各种类型的超导量子比特,被困在一个腔中的原子,或者耦合到一个谐振器的量子点。

A Proposal for Realizing a 3-Qubit Controlled-Phase Gate with Superconducting Qubit Systems Coupled to a Cavity
We present a way to realize a 3-qubit quantum controlled-phase gate with superconducting qubit systems coupled to a cavity. This proposal does not require adjustment of the qubit level spacings or identical qubit-cavity coupling constants. Moreover, since only a resonant interaction is applied, the gate can be performed fast, within $\sim $ 10 nanosecond. This proposal is quite general, which can be applied to various types of superconducting qubits, atoms trapped in a cavity, or quantum dots coupled to a resonator.
