Description
One of the challenges of scaling up quantum processors is the optimization of the quantum gates, as each gate may require different control parameters. We developed and tested a fast protocol to automatically calibrate the entangling 2-qubit Mølmer Sørensen gate using Bayesian parameter estimation. Such a protocol promises to increase experimental uptime by decreasing the time needed for calibration, as well as allowing automated operation. Our protocol achieves a median infidelity of 0.13(1)% caused by miscalibration in $1200+/-500$ experimental shots. This paves the way to decouple quantum circuits from their implementation on ion trap hardware, allowing operation by an end user without detailed knowledge of the physical realization.
