Spectral signature of high-order photon processes enhanced by Cooper-pair pairing
W. C. Smith, A. Borgognoni, M. Villiers +7
Inducing interactions between individual photons is key for photonic quantum information and studying many-body photon states. Superconducting circuits are well suited to combine s…

Dynamically enhancing qubit-photon interactions with anti-squeezing
M. Villiers, W. C. Smith, A. Petrescu +7
The interaction strength of an oscillator to a qubit grows with the oscillator's vacuum field fluctuations. The well known degenerate parametric oscillator has revived interest in…
