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…
Magnon polaritons in a van der Waals ferromagnet coupled to a superconducting resonator
Alvaro Bermejillo-Seco, Luuk J. van der Goot, Matteo Arfini +3
Achieving magnon-photon hybridization in the microwave regime is essential for integrating magnetic excitations with superconducting circuits. While this has been extensively demon…
Magnon-magnon interaction induced by nonlinear spin wave dynamics
Matteo Arfini, Alvaro Bermejillo-Seco, Artem Bondarenko +4
We experimentally and theoretically demonstrate that nonlinear spin-wave dynamics can induce an effective resonant interaction between non-resonant magnon modes in a yttrium iron g…
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…
