Robust readout of bosonic qubits in the dispersive coupling regime

2018 · Physical Review A

High-fidelity qubit measurements play a crucial role in quantum computation, communication, and metrology. In recent experiments, it has been shown that readout fidelity can be improved by performing repeated quantum nondemolition (QND) readouts of a …

Hardware-Efficient Quantum Random Access Memory with Hybrid Quantum Acoustic Systems

2019 · Physical Review Letters

Hybrid quantum systems in which acoustic resonators couple to superconducting qubits are promising quantum information platforms. High quality factors and small mode volumes make acoustic modes ideal quantum memories, while the qubit-phonon coupling enables the …
