Level attraction and idler resonance in a strongly driven Josephson cavity
F. Fani Sani, I. C. Rodrigues, D. Bothner +1
Nonlinear Josephson circuits play a crucial role in the growing landscape of quantum information and technologies. The typical circuits studied in this field consist of qubits, who…
Cooling photon-pressure circuits into the quantum regime
I. C. Rodrigues, D. Bothner, G. A. Steele
Quantum control of electromagnetic fields was initially established in the optical domain and has been advanced to lower frequencies in the gigahertz range during the past decades…
Current detection using a Josephson parametric upconverter
Felix E. Schmidt, Daniel Bothner, Ines C. Rodrigues +3
We present the design, measurement and analysis of a current sensor based on a process of Josephson parametric upconversion in a superconducting microwave cavity. Terminating a cop…
Coupling microwave photons to a mechanical resonator using quantum interference
I. C. Rodrigues, D. Bothner, G. A. Steele
In recent years, the field of microwave optomechanics has emerged as leading platform for achieving quantum control of macroscopic mechanical objects. Implementations of microwave…
