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 …

Universal Control of an Oscillator with Dispersive Coupling to a Qubit
2015 · arXiv (Cornell University)
We investigate quantum control of an oscillator mode off-resonantly coupled to an ancillary qubit. In the strong dispersive regime, we may drive the qubit conditioned on number states of the oscillator, which together with displacement …

Surpassing millisecond coherence times in on-chip superconducting quantum memories by optimizing materials, processes, and circuit design
2023 · arXiv (Cornell University)
The performance of superconducting quantum circuits for quantum computing has advanced tremendously in recent decades; however, a comprehensive understanding of relaxation mechanisms does not yet exist. In this work, we utilize a multimode approach to …
