Multiplying and detecting propagating microwave photons using inelastic Cooper-pair tunneling
Juha Leppäkangas, Michael Marthaler, Dibyendu Hazra +5
The interaction between propagating microwave fields and Cooper-pair tunneling across a DC voltage-biased Josephson junction can be highly nonlinear. We show theoretically that thi…
Estimating the error of an analog quantum simulator by additional measurements
Iris Schwenk, Sebastian Zanker, Jan-Michael Reiner +2
We study an analog quantum simulator coupled to a reservoir with a known spectral density. The reservoir perturbs the quantum simulation by causing decoherence. The simulator is us…
Creating photon-number squeezed strong microwave fields by a Cooper-pair injection laser
Martin Koppenhöfer, Juha Leppäkangas, Michael Marthaler
The use of artificial atoms as an active lasing medium opens a way to construct novel sources of nonclassical radiation. An example is the creation of photon-number squeezed light.…
