Original Abstract Submitted

a computing system including a quantum computing device. the quantum computing device includes a island, a quantum dot (qd), an electrical ground, and a capacitance sensor. the computing system further includes a controller configured to, in each of a plurality of sampling iterations, control the quantum computing device to electrically couple the island to the electrical ground, disconnect the island from the electrical ground, electrically couple the island to the qd, scan over values of a first plunger gate voltage applied to a first plunger gate and a second plunger gate voltage applied to a second plunger gate, and output quantum capacitance measurements. the controller is further configured to receive the quantum capacitance measurements and determine a measured distribution of resonance regions associated with the sampling iterations. the controller is further configured to identify a minimum-energy resonance region and output the minimum-energy resonance region identification.
