METHOD OF OPERATING A SEMICONDUCTOR SPIN QUBIT QUANTUM COMPUTER
Abstract
A method of operating a quantum processor (10) comprising a plurality of gate electrodes arranged on a semiconductor heterostructure, wherein the plurality of gate electrodes comprises conveyor gate electrodes configured to be supplied with at least one voltage V to move at least one qubit, arranged in the semiconductor heterostructure, along the at least one path to a manipulation zone for manipulating the at least one qubit is disclosed. The method comprises the steps of calibrating the at least one voltage V supplied to the gate electrodes; determining at least one fidelity FM or an error syndrome S, relating to manipulating the at least one qubit at the manipulation zone; and adjusting the at least one voltage V.
