Quantum Accelerator: Memory-enhanced quantum sensing for GPS-denied Navigation

Abstract

Quantum logic gates between electron and nuclear spin qubits with high fidelity are required for the estimation algorithms. We experimentally investigated a new approach using dynamically corrected geometric quantum logic gates that promises to yield high fidelity even in the presence of dephasing. We developed a custom hardware and software solution to carry out the dynamically corrected quantum logic gates, and implemented them in our system. We implemented and troubleshot randomized benchmarking protocols to characterize the fidelity of the gates, which involved understanding sources of systematic noise and other error sources in our system.
