Analysis of calibration techniques for single-qubit gates on a superconducting quantum computer — •Kathrin König1, Naoki Kanazawa2, and Shota Nakasuji3 — 1Fraunhofer IAF, Freiburg, Germany — 2IBM Research, Tokyo, Japan — 3University of Tokyo, Tokyo, Japan
Inexact calibrated gates and environmental influences lead to imperfect outcomes of a quantum computation. We investigate two calibration techniques on an IBM quantum computer. The state-of-the art calibration uses an empirical formula to update the optimal control parameter. The compared new technique can directly estimate the parameter at arbitrary precision. We confirmed that the new technique shows higher precision with comparable accuracy.
