"Optimal Experimental Design for Quantum Circuits: A case study for the mitigation of quasiparticle poisoning"

Presented by Paul Baity, Brookhaven National Laboratory

Superconducting circuits are one of the most widely used systems for quantum computing, and many of the key accomplishments in this field have been performed using superconducting-based quantum processors. The improvement of device performance through the mitigation and control of qubit errors is currently a critical step for the implementation of large-scale quantum computing. However, the experimental routines used to test error mitigation strategies are often pointwise, time-consuming, and costly. Instead of unguided research, Optimal Experimental Design (OED) is a methodological approach used to maximize the information gained from a limited number of iteratively designed experiments. We are developing such a methodology for the design of quantum circuits. To demonstrate the benefits of our OED methodology, we apply it to the problem of quasiparticle poisoning (QP) in superconducting quantum devices, wherein environmental high-energy radiation creates qubit errors. Our OED methodology uses key advances in the computational simulation of QP physics and HPC optimization techniques to design quantum chips that are more resilient against QP-induced errors. Present results and ongoing work will be discussed.
