Abstract
A computing system including a quantum computing device. The quantum computing device includes Majorana islands, quantum dots, and capacitance sensors. The computing system further includes a controller configured to, for an island-dot system including one or more Majorana islands and one or more quantum dots, control the quantum computing device to perform a joint parity measurement of two or more MZMs. Performing the joint parity measurement includes, at each of a plurality of candidate resonance regions corresponding to values of a change in a fermion number, setting Majorana island gate voltages and quantum dot gate voltages to respective candidate resonance values. The joint parity measurement further includes, at each of the candidate resonance regions, via a capacitance sensor, detecting a microwave response signal measured at the island-dot system. The joint parity measurement further includes outputting a joint parity value based at least in part on the microwave response signal.
