Europe’s QMiCS and its Work in Quantum Microwaves for Communication & Sensing

(AzoNano) Frank Deppe, Junior Group Leader for Superconducting Quantum Circuits at the Walther-Meißner-Institut, explains QMiCS and the work that it does in this interview with AZoNano.
“Quantum Microwaves for Communication and Sensing” (QMiCS) is one out of 20 projects which got funded in the highly competitive first call of the European Quantum Technology Flagship Program. Within this program, QMiCS is still a basic science project, where academic research groups collaborate with selected commercial companies. The main task of QMiCS is to explore the potential of non-classical propagating microwaves, whose behavior is controlled by the laws of quantum mechanics, for future applications and commercial exploitation.
Superconducting circuits themselves cover the whole spectrum of quantum technology: quantum computing, quantum simulation, quantum communication, and quantum sensing & metrology. The propagating continuous-variable quantum microwaves investigated within QMiCS are most promising for quantum communication and quantum sensing. In quantum microwave communication, a quantum local area network would allow for intrinsically secure communication and for distributed computing between multiple quantum processors. With respect to sensing, the most compelling application of quantum microwaves is quantum radar,
