论文摘要
我们回顾了一些为超导设备设计和工程效率量子的一些努力,重点是Gottesman-Kitaev-Preskill(GKP)量子。我们提出了一些新的结果,该结果涉及使用有限切入的GKP Ancilla Qubits解码重复的GKP误差校正,并与先前研究的随机误差模型显示出差异。我们讨论了电路定点的方法来实现GKP量子位之间的CZ门,并讨论了在可扩展的超导表面代码体系结构中使用GKP和常规量子器作为构建块的不同方案。
We review some of the recent efforts in devising and engineering bosonic qubits for superconducting devices, with emphasis on the Gottesman-Kitaev-Preskill (GKP) qubit. We present some new results on decoding repeated GKP error correction using finitely-squeezed GKP ancilla qubits, exhibiting differences with previously studied stochastic error models. We discuss circuit-QED ways to realize CZ gates between GKP qubits and we discuss different scenario's for using GKP and regular qubits as building blocks in a scalable superconducting surface code architecture.
