Brillouin light scattering by magnetic quasi-vortices in cavity optomagnonics
A. Osada, A. Gloppe, R. Hisatomi +5
A ferromagnetic sphere can support \textit{optical vortices} in forms of whispering gallery modes and \textit{magnetic quasi-vortices} in forms of magnetostatic modes with non-triv…
Qubit-assisted transduction for a detection of surface acoustic waves near the quantum limit
Atsushi Noguchi, Rekishu Yamazaki, Yutaka Tabuchi +1
We demonstrate ultra-sensitive measurement of fluctuations in a surface-acoustic-wave~(SAW) resonator using a hybrid quantum system consisting of the SAW resonator, a microwave (MW…
Information-to-work conversion by Maxwell's demon in a superconducting circuit-QED system
Y. Masuyama, K. Funo, Y. Murashita +6
The gedanken experiment of Maxwell's demon has led to the studies concerning the foundations of thermodynamics and statistical mechanics. The demon measures fluctuations of a syste…
Electro-mechano-optical detection of nuclear magnetic resonance
Kazuyuki Takeda, Kentaro Nagasaka, Atsushi Noguchi +5
Signal reception of nuclear magnetic resonance (NMR) usually relies on electrical amplification of the electromotive force caused by nuclear induction. Here, we report up-conversio…
Cavity optomechanics with surface acoustic waves
Ayato Okada, Fumikazu Oguro, Atsushi Noguchi +4
We report a development of an electro-optomechanical system based on a surface acoustic wave (SAW), where a piezoelectric material with a large optoelastic susceptibility is used f…
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…
