Symmetries and model reduction in a transmon qubit
Erwan Roverc'h, Kyrylo Gerashchenko, Alvise Borgognoni +4
Engineered symmetries in superconducting circuits can protect quantum information; much like selection rules in atomic physics, they forbid transitions between the qubit states. Pr…
Experimental realization of a transmon qubit
Erwan Roverc'h, Alvise Borgognoni, Marius Villiers +7
Superconducting circuits with embedded symmetries are good candidates to robustly protect quantum information from dominant error channels. The qubit, consisting of an i…
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…
