Quantum annealing in capacitively coupled Kerr parametric oscillators using frequency-chirped drives
T. Yamaji, S. Masuda, Y. Kano +7
We study parametric oscillations of two capacitively coupled Kerr parametric oscillators (KPOs) with frequency-chirped two- and one-photon drives. The two-KPO system adiabatically…
Theoretical study of reflection spectroscopy for superconducting quantum parametrons
S. Masuda, A. Yamaguchi, T. Yamaji +4
Superconducting parametrons in the single-photon Kerr regime, also called KPOs, have been attracting increasing attention in terms of their applications to quantum annealing and un…
Displacement of propagating squeezed microwave states
Kirill G. Fedorov, L. Zhong, S. Pogorzalek +16
Displacement of propagating quantum states of light is a fundamental operation for quantum communication. It enables fundamental studies on macroscopic quantum coherence and plays…
Correlated emission lasing in harmonic oscillators coupled via a single three-level artificial atom
Z. H. Peng, Yu-xi Liu, J. T. Peltonen +3
A single superconducting artificial atom provides a unique basis for coupling electromagnetic fields and photons hardly achieved with a natural atom. Bringing a pair of harmonic os…
Josephson parametric phase-locked oscillator and its application to dispersive readout of superconducting qubits
Z. R. Lin, K. Inomata, K. Koshino +4
The parametric phase-locked oscillator (PPLO), also known as a parametron, is a resonant circuit in which one of the reactances is periodically modulated. It can detect, amplify, a…
Observation of three-state dressed states in circuit quantum electrodynamics
K. Koshino, H. Terai, K. Inomata +4
We have investigated the microwave response of a transmon qubit coupled directly to a transmission line. In a transmon qubit, owing to its weak anharmonicity, a single driving fiel…
