Amplified and tunable transverse and longitudinal spin-photon coupling in hybrid circuit-QED
Neill Lambert, Mauro Cirio, Matthieu Delbecq +4
We describe a method to tune, in-situ, between transverse and longitudinal light-matter coupling in a hybrid circuit-QED device composed of an electron spin degree of freedom coupl…
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…
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…
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…
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…
