Few-photon degenerate parametric resonance in a two-tone driven microwave resonator
Orjan Ameye, Jakob Koenig, Clinton Potts +2
Multi-tone external driving offers a route to parametric physics without directly modulating the device. However, the validity of the parametric response in the few-photon regime r…

Collapse and Inversion of the Josephson Potential in a Strongly Driven Superconducting Circuit
Sercan Deve, Marius Villiers, Marijn A. Morssink +2
The authors design a transmon‑resonator system that avoids unwanted transitions under strong microwave driving, allowing them to observe the Josephson potential collapsing to zero…

All-microwave Lamb shift engineering for a fixed frequency multi-level superconducting qubit
Byoung-moo Ann, Gary A. Steele
It is known that the electromagnetic vacuum is responsible for the Lamb shift, which is a crucial phenomenon in quantum electrodynamics (QED). In circuit QED, the readout or bus re…
