Direct detection of down-converted photons spontaneously produced at a single Josephson junction
Dorian Fraudet, Izak Snyman, Denis M. Basko +7
We study spontaneous photon decay into multiple photons triggered by strong non-linearities in a superconducting quantum simulator of the boundary sine-Gordon impurity model. Previ…

Universal control of a bosonic mode via drive-activated native cubic interactions
Axel M. Eriksson, Théo Sépulcre, Mikael Kervinen +9
Linear bosonic modes offer a hardware-efficient alternative for quantum information processing but require access to some nonlinearity for universal control. The lack of nonlineari…

Particle Production in Ultra-Strong Coupling Waveguide QED
Nicolas Gheeraert, Xin H. H. Zhang, Théo Sépulcre +4
Understanding large-scale interacting quantum matter requires dealing with the huge number of quanta that are produced by scattering even a few particles against a complex quantum…
