Ultra-Weak-Pump Microwave-to-Optical Quantum Transduction via a Single Color Center
Kyosuke Goto, Hodaka Kurokawa, Hideo Kosaka +1
Scaling up superconducting quantum processors remains a central challenge for realizing fault-tolerant quantum computation. Although distributed architectures based on optical phot…
High-gain and large-bandwidth Josephson parametric amplifier influenced by Fabry-Pérot interference
Shingo Kono, Jesper Ilves, Arjan F. van Loo +8
Quantum-limited parametric amplifiers are essential components for many quantum technologies operating in the microwave domain. Achieving both high gain and broad bandwidth, howeve…
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…
Galvanically connected tunable coupler between a cavity and a waveguide
Kazuki Koshino
One of the key technologies in recent quantum devices is the tunable coupling among quantum elements such as qubits, cavities, and waveguides. In this work, we propose a cavity-wav…
Labeling eigenstates of qubit-cavity systems based on the continuity of qubit occupancy: Detecting resonances to higher excited qubit states
Shimpei Goto, Kazuki Koshino
We propose a new method for labeling the eigenstates of qubit-cavity systems based on the continuity of the qubit occupancy. The labeled eigenstates give a rough estimate of the ev…
Diamond optomechanical cavity with a color center for microwave-to-optical quantum interfaces
Byunggi Kim, Hodaka Kurokawa, Katsuta Sakai +3
Quantum transduction between microwave and optical photons plays a key role in quantum communication among remote qubits. Although the quantum transduction schemes generating commu…
