Multimode physics of the unimon circuit
Sasu Tuohino, Vasilii Vadimov, Wallace S. Teixeira +3
We consider a superconducting half-wavelength resonator that is grounded at its both ends and contains a single Josephson junction. Previously this circuit was considered as a unim…

Quantum-circuit refrigeration of a superconducting microwave resonator well below a single quantum
Arto Viitanen, Timm Mörstedt, Wallace S. Teixeira +4
We experimentally demonstrate a recently proposed single-junction quantum-circuit refrigerator (QCR) as an in-situ-tunable low-temperature environment for a superconducting 4.7-GHz…

Inducing nontrivial qubit coherence through a controlled dispersive environment
W. S. Teixeira, F. Nicacio, F. L. Semião
We show how the dispersive regime of the Jaynes-Cummings model may serve as a valuable tool to the study of open quantum systems. We employ it in a bottom-up approach to build an e…
