Methods and Results for Quantum Optimal Pulse Control on Superconducting
  Qubit Systems
The effective use of current Noisy Intermediate-Scale Quantum (NISQ) devices
is often limited by the noise which is caused by interaction with the
environment and affects the fidelity of quantum gates. In transmon qubit
systems, the quantum gate fidelity can be improved by applying control pulses
that can minimize the effects of the environmental noise. In this work, we
employ physics-guided quantum optimal control strategies to design optimal
pulses driving quantum gates on superconducting qubit systems. We test our
results by conducting experiments on the IBM Q hardware using their OpenPulse
API. We compare the performance of our pulse-optimized quantum gates against
the default quantum gates and show that the optimized pulses improve the
fidelity of the quantum gates, in particular the single-qubit gates. We discuss
the challenges we encountered in our work and point to possible future
improvements.
