High-Impedance Microwave Resonators with Two-Photon Nonlinear Effects
S. Andersson, H. Havir, A. Ranni +2
In this article, we present an experimental study of a Josephson junction -based high-impedance resonator. By taking the resonator to the limit of consisting effectively only of on…

Continuous microwave photon counting by semiconductor-superconductor hybrids
Subhomoy Haldar, David Barker, Harald Havir +4
The growing interest in quantum information has enabled the manipulation and readout of microwave photon states with high fidelities. The presently available microwave photon count…

Real-time observation of Cooper pair splitting showing strong non-local correlations
Antti Ranni, Fredrik Brange, Elsa T. Mannila +2
Controlled generation and detection of quantum entanglement between spatially separated particles constitute an essential prerequisite both for testing the foundations of quantum m…
