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…
