High coherence annealing, Part 1: fast, high-fidelity readout
Abstract
Recently developed capacitively-shunted flux qubits offer a promising path toward building a high-coherence quantum annealer. These qubits take advantage of lower persistent currents to achieve lower noise sensitivity. As such, readout of their state at the end of the anneal operation presents unique challenges. We report experimental results of a persistent current readout scheme that provides fast readout while isolating the qubit from the resonator during the anneal.
