论文摘要
超导电路中的高质量因子3D腔是玻色旋逻辑Qubits的理想候选者，因为它们的保真度仅受到低光子损耗率的限制。然而，用于操纵骨气缸的transmon量子台导致出现额外的松弛和衰减通道。在这项工作中，进行了数值研究，以阐明各种损失通道对逻辑门在骨乘量子方面的性能的影响。开发了一个门误差模型，该模型封装了任意门操作的损失机制，并预测了玻色粒量子的实验可实现的门错误。从这项研究中收集到的损失机制中收集的见解表明，更有效的优化算法可以减少玻色粒的门错误。
High-quality-factor 3D cavities in superconducting circuits are ideal candidates for bosonic logical qubits as their fidelity is limited only by the low photon loss rate. However, the transmon qubits that are used to manipulate bosonic qubits result in the emergence of additional relaxation and dephasing channels. In this work, a numerical study is performed to elucidate the effect of the various loss channels on the performance of logical gates on a bosonic qubit. A gate error model is developed that encapsulates the loss mechanisms for arbitrary gate operations and predicts experimentally achievable gate errors for bosonic qubits. The insights gleaned from this study into loss mechanisms suggest more efficient optimization algorithms that could reduce gate errors on bosonic qubits.
