摘要:

我们提出并分析了一种实现片上可扩展级联量子器件的无源架构。与标准方法相比,我们的方案不依赖于破坏洛伦兹互易性。相反,我们设计了超导transmon量子比特对和微波传输线之间的相互作用,使得两个离域正交激发发射(和吸收)沿相反方向传播的光子。我们展示了如何利用这种级联的量子器件来被动地探测和测量静止量子比特的量子寄存器上的复杂多体算子,从而实现遥远量子比特之间的量子态的预示性转移,以及用于量子纠错的稳定码的生成和操纵。

英文摘要:

We propose and analyze a passive architecture for realizing on-chip, scalable cascaded quantum devices. In contrast to standard approaches, our scheme does not rely on breaking Lorentz reciprocity. Rather, we engineer the interplay between pairs of superconducting transmon qubits and a microwave transmission line, in such a way that two delocalized orthogonal excitations emit (and absorb) photons propagating in opposite directions. We show how such cascaded quantum devices can be exploited to passively probe and measure complex many-body operators on quantum registers of stationary qubits, thus enabling the heralded transfer of quantum states between distant qubits, as well as the generation and manipulation of stabilizer codes for quantum error correction.
