1. A method for calibrating quantum gates in a quantum computing system, the method comprising:
determining an amount of entanglement θ of at least a pair of quantum gates in the quantum computing system;
comparing the determined amount of entanglement θ to a target entanglement value based on a parity signal obtained from a calibration circuit of the quantum computing system; and
when the determined amount of entanglement θ is not the target entanglement value, adjusting at least one of an optical and a radio frequency (RF) power applied to the pair of quantum gates until the parity signal corresponds to the target entanglement value.
