Patent number: 11928554Abstract: While a qubit control system (e.g., a laser system) is in a first configuration, it causes a qubit state (as represented as a point on the surface of a Bloch sphere) of a quantum state carrier (QSC), e.g., an atom, to rotate in a first direction from an initial qubit state to a first configuration qubit state. While the qubit control system is in a second configuration, it causes the QSC state to rotate in a second direction opposite the first direction from the first configuration qubit state to a second configuration qubit state. The second configuration qubit state is read out as a |0 or |1. Repeating these actions results in a distribution of |0s and |1s that can be used to determine which of the two configurations results in higher Rabi frequencies. Iterating the above for other pairs of configurations can identify a configuration that delivers the most power to the QSC and thus yields the highest Rabi frequency.Type: GrantFiled: January 17, 2023Date of Patent: March 12, 2024Assignee: ColdQuanta, Inc.Inventors: Daniel C. Cole, Woo Chang Chung
