Engineered two-photon dissipative confinement of a Kerr-cat qubit using SISIS quantum circuit refrigerator
Shumpei Masuda, Tsuyoshi Yamamoto, Shuji Nakamura +2
Kerr-cat qubits realized in periodically driven superconducting nonlinear resonators are a promising platform for quantum information processing with biased noise. Pure dephasing i…
Heat rectification through a quantum two-level system
Tsuyoshi Yamamoto, Manuel Houzet
We study heat rectification through a quantum two-level system asymmetrically coupled to two thermal baths, as described by the Ohmic spin-boson model. We evaluate the steady-state…
Four-body coupler for superconducting qubits based on Josephson parametric oscillators
Ryoji Miyazaki, Tsuyoshi Yamamoto
We theoretically propose a circuit of the four-body coupler for superconducting qubits based on Josephson parametric oscillators (JPOs). Our coupler for the four-body interaction h…
Stabilization of Kerr-cat qubits with quantum circuit refrigerator
Shumpei Masuda, Shunsuke Kamimura, Tsuyoshi Yamamoto +2
A periodically-driven superconducting nonlinear resonator can implement a Kerr-cat qubit, which provides a promising route to a quantum computer with a long lifetime. However, the…
Thermal transport across a Josephson junction in a dissipative environment
Tsuyoshi Yamamoto, Leonid I. Glazman, Manuel Houzet
At zero temperature, a Josephson junction coupled to an ohmic environment displays a quantum phase transition between superconducting and insulating phases, depending whether the r…
