论文摘要
通过量子体积测量，我们改善了量子电路在超导量子计算系统上的质量，并结合了动态解耦，编译器优化，较短的两倍Quibent Gates和激发态促进读数的组合。该结果表明，通往较大量子体积系统的途径需要同时提高相干性，控制门的保真度，测量保真度和更智能的软件，这些软件考虑了硬件详细信息，从而证明需要继续为可预见的未来共同设计软件和硬件堆栈。
We improve the quality of quantum circuits on superconducting quantum computing systems, as measured by the quantum volume, with a combination of dynamical decoupling, compiler optimizations, shorter two-qubit gates, and excited state promoted readout. This result shows that the path to larger quantum volume systems requires the simultaneous increase of coherence, control gate fidelities, measurement fidelities, and smarter software which takes into account hardware details, thereby demonstrating the need to continue to co-design the software and hardware stack for the foreseeable future.
