Heat Modulation on Target Thermal Bath via Coherent Auxiliary Bath

open access: yesEntropy, 2021
We study a scheme of thermal management where a three-qubit system assisted with a coherent auxiliary bath (CAB) is employed to implement heat management on a target thermal bath (TTB). We consider the CAB/TTB being ensemble of coherent/thermal two-level

New material platform for superconducting transmon qubits with coherence times exceeding 0.3 milliseconds

open access: yesNature Communications, 2021
Quantum computers based on superconducting transmon qubits are limited by single qubit lifetimes and coherence times, which are orders of magnitude shorter than limits imposed by bulk material properties.
