Microwave Squeezing with Superconducting (meta)materials

The MiSS project targets transformative progress in the emerging field of distributed quantum sensing exploiting multi-mode microwave squeezing. The final goal is to realise a robust and scalable technology for microwave squeezing and generation of non-classical microwave radiation based on superconducting (meta)materials. The three specific objectives of the MiSS project are: 1) Technological innovation, investigating new material and scalable microfabrication approaches to optimise the building blocks to produce Travelling Wave Parametric Amplifiers-based squeezers; 2) Metrology protocols, developing dedicated cryogenic measurement protocols to accurately evaluate the radiation quantumness, opening the way to standardisation; 3) Realisation of a prototype for real world applications, developing a system with scalability potential for distributed quantum sensing in the microwave regime. A use-case dedicated to multi-parameter sensing for material characterisation will be targeted. The outcomes of this project will pave the way towards real exploitation of quantum-enhanced sensing techniques in the microwave regime. The MiSS consortium brings together a unique set of expertise in design, materials, metrology, fabrication, cryogenic characterisation and commercialisation to be able to deliver on this ambitious goal.
