Improving Quantum Gate Fidelities by Using a Qubit to Measure Microwave Pulse Distortions

We present a new method for determining pulse imperfections and improving the single-gate fidelity in a superconducting qubit. By applying consecutive positive and negative π pulses, we amplify the qubit evolution due to microwave pulse distortions, which causes the qubit state to rotate around an a...
