Widely tunable on-chip microwave circulator for superconducting quantum circuits

BJ Chapman, EI Rosenthal, J Kerckhoff, BA Moores… - Physical Review X, 2017 - APS
We report on the design and performance of an on-chip microwave circulator with a widely
(GHz) tunable operation frequency. Nonreciprocity is created with a combination of …

Towards generic adiabatic elimination for bipartite open quantum systems

R Azouit, F Chittaro, A Sarlette… - Quantum Science and …, 2017 - iopscience.iop.org
We consider a composite open quantum system consisting of a fast subsystem coupled to a
slow one. Using the time scale separation, we develop an adiabatic elimination technique to …
