Optically Switched Phonon Superradiance of Surface Acoustic Wave in Diamond
Zhiwei Chen, Changyong Lei, Jie Ren
Surface acoustic wave (SAW) phonon coupling with nitrogen-vacancy (NV) center spins in diamond offers a promising platform for on-chip quantum phononic manipulations. Although an e…
Superconducting Quantum Memory with a Suspended Coaxial Resonator
Lev Krayzman, Chan U Lei, Suhas Ganjam +3
A promising way to store quantum information is by encoding it in the bosonic excitations of microwave resonators. This provides for long coherence times, low dephasing rates, as w…
Surpassing millisecond coherence times in on-chip superconducting quantum memories by optimizing materials, processes, and circuit design
Suhas Ganjam, Yanhao Wang, Yao Lu +10
The performance of superconducting quantum circuits for quantum computing has advanced tremendously in recent decades; however, a comprehensive understanding of relaxation mechanis…
Demonstrating a superconducting dual-rail cavity qubit with erasure-detected logical measurements
Kevin S. Chou, Tali Shemma, Heather McCarrick +31
A critical challenge in developing scalable error-corrected quantum systems is the accumulation of errors while performing operations and measurements. One promising approach is to…
Microwave loss characterization using multi-mode superconducting resonators
Chan U Lei, Suhas Ganjam, Lev Krayzman +5
Measuring the losses arising from different materials and interfaces is crucial to improving the coherence of superconducting quantum circuits. Although this has been of interest f…
Acoustic radiation from a superconducting qubit: From spontaneous emission to Rabi oscillations
Vijay Jain, Vladislav D. Kurilovich, Yanni D. Dahmani +6
Acoustic spontaneous emission into bulk dielectrics can be a strong source of decoherence in quantum devices, especially when a qubit is in the presence of piezoelectric materials.…
