Focusing Surface-Acoustic-Wave Resonators on Thin-Film Lithium Niobate with Transverse-Mode Suppression
Ryo Sasaki, Ryusuke Hisatomi, Rekishu Yamazaki +3
Surface-acoustic-wave (SAW) resonators are a promising platform for constructing hybrid quantum systems, where confined acoustic waves enable strong interaction with various physic…
Resonance fluorescence spectra of a driven Kerr nonlinear resonator
Aree Taguchi, Katsuta Sakai, Aiko Yamaguchi +11
Resonance fluorescence spectra of a driven Kerr nonlinear resonator is investigated both theoretically and experimentally. When the Kerr nonlinear resonator is driven strongly such…
Photon-noise-tolerant dispersive readout of a superconducting qubit using a nonlinear Purcell filter
Yoshiki Sunada, Kenshi Yuki, Zhiling Wang +7
Residual noise photons in a readout resonator become a major source of dephasing for a superconducting qubit when the resonator is optimized for a fast, high-fidelity dispersive re…
On orbital angular momentum conservation in Brillouin light scattering within a ferromagnetic sphere
A. Osada, A. Gloppe, Y. Nakamura +1
Magnetostatic modes supported by a ferromagnetic sphere have been known as the Walker modes, each of which possesses an orbital angular momentum as well as a spin angular momentum…
Quantum non-demolition detection of an itinerant microwave photon
S. Kono, K. Koshino, Y. Tabuchi +2
Photon detectors are an elementary tool to measure electromagnetic waves at the quantum limit and are heavily demanded in the emerging quantum technologies such as communication, s…
Nonclassical photon number distribution in a superconducting cavity under a squeezed drive
S. Kono, Y. Masuyama, T. Ishikawa +5
A superconducting qubit in the strong dispersive regime of a circuit quantum electrodynamics system is a powerful probe for microwave photons in a cavity mode. In this regime, a qu…
Single-shot readout of a superconducting flux qubit with a flux-driven Josephson parametric amplifier
Z. R. Lin, K. Inomata, W. D. Oliver +4
We report single-shot readout of a superconducting flux qubit by using a flux-driven Josephson parametric amplifier (JPA). After optimizing the readout power, gain of the JPA and t…
