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…
Dephasing in a crystal-phase defined double quantum dot charge qubit strongly coupled to a high-impedance resonator
Antti Ranni, Subhomoy Haldar, Harald Havir +8
Dephasing of a charge qubit is usually credited to charge noise in the environment. Here we show that charge noise may not be the limiting factor for the qubit coherence. To this e…
High Impedance Josephson Junction Resonators in the Transmission Line Geometry
Antti Ranni, Harald Havir, Subhomoy Haldar +1
In this article we present an experimental study of microwave resonators made out of Josephson junctions. The junctions are embedded in a transmission line geometry so that they in…
Local and non-local two-electron tunneling processes in a Cooper pair splitter
Antti Ranni, Elsa T. Mannila, Axel Eriksson +3
We measure the tunneling rates and coupling coefficients for local Andreev, non-local Andreev and elastic cotunneling processes. The non-local Andreev process, giving rise to Coope…
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…
