论文摘要
放射性最近被发现是超导量子处理器的现实实现的分流和相关误差的来源。在这项工作中，我们测量了在典型的实验室环境中存在的放射性水平（从天然存在的放射性同位素发出的若虫，中子和伽玛）以及最常用的材料中，用于组装和运行最先进的超导量子。我们开发了基于GEANT-4的模拟，以预测从每个上述来源的量子芯片中释放的影响速率和能量量。我们最终提出了在无线电环境中下一代Qubits操作的缓解策略。
Radioactivity was recently discovered as a source of decoherence and correlated errors for the real-world implementation of superconducting quantum processors. In this work, we measure levels of radioactivity present in a typical laboratory environment (from muons, neutrons, and gamma's emitted by naturally occurring radioactive isotopes) and in the most commonly used materials for the assembly and operation of state-of-the-art superconducting qubits. We develop a GEANT-4 based simulation to predict the rate of impacts and the amount of energy released in a qubit chip from each of the mentioned sources. We finally propose mitigation strategies for the operation of next-generation qubits in a radio-pure environment.
