Fast Unconditional Reset and Leakage Reduction of a Tunable
Superconducting Qubit via an Engineered Dissipative Bath
Rapid and accurate initialization of qubits, reset, is a crucial building block for various tasks in quantum information processing, such as quantum error-correction and estimation of statistics of noisy quantum devices with many qubits. We demonstrate unconditional reset of a frequency-tunable transmon qubit that simultaneously resets multiple excited states by …
