摘要:

我们研究了一个利用超导芯片上传输线谐振器中的微波光子作为量子比特的量子计算系统。我们表明,量子计算所需的所有控制都可以通过耦合到同一芯片上的约瑟夫森器件来实现,并利用它们固有的强非线性来实现量子比特相互作用。我们分析了门错误率,以证明我们的计划是现实的,即使是有限的退相干时间的约瑟夫森器件。基于现有技术的概念创新解决方案,我们的方案提供了一个集成和可扩展的方法,光子量子位量子计算的下一个关键里程碑。

英文摘要:

We study a quantum computing system using microwave photons in transmission line resonators on a superconducting chip as qubits. We show that all control necessary for quantum computing can be implemented by coupling to Josephson devices on the same chip, and take advantage of their strong inherent nonlinearities to realize qubit interactions. We analyze the gate error rate to demonstrate that our scheme is realistic even for Josephson devices with limited decoherence times. A conceptually innovative solution based on existing technologies, our scheme provides an integrated and scalable approach to the next key milestone for photonic qubit quantum computing.
