Kirill Viktorovich Petrovnin, Jiaming Wang, Gheorghe Sorin Paraoanu · Communications Physics · 2025
The ability to detect microwave signals at the level of single quanta is essential for applications in low-temperature quantum technologies. Here the authors provide a model for critical parametric sensing with a superconducting circuit and obtain the relevant analytical and numerical results.
