Engineering Large Stark Shifts for Control of Individual Clock State Qubits
Aaron C. Lee, Jacob Smith, Philip Richerme +4
In quantum information science, the external control of qubits must be balanced with the extreme isolation of the qubits from the environment. Atomic qubit systems typically mitiga…
