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 …

Characterizing low-frequency qubit noise

2022 · arXiv (Cornell University)

Fluctuations of the qubit frequencies are one of the major problems to overcome on the way to scalable quantum computers. Of particular importance are fluctuations with the correlation time that exceeds the decoherence time due …
