Multimode cOrrelations in microwave photonics with Superconducting quAntum Circuits

Photonic multimode continuous variable (CV) quantum states have been experimentally demonstrated at optical frequencies, but they are still not established in the microwave regime. “Mosaic” addresses this challenge, aiming at demonstrating multimode entangled quantum states with Josephson meta-materials. Quantum states of light consisting of many entangled modes (multimode entangled states) provide a powerful quantum resource and have been recently proposed as a platform for universal quantum computing. The aim of this project is to generate broadband multimode entangled states for the first time in the microwave regime. Superconducting quantum circuits, specifically, Josephson meta-materials, are used to generate and control quantum correlations between different frequency modes in microwave photons. The experimental proof that Josephson-metamaterial can be successfully used as sources of itinerant quantum states of microwave radiation represents a decisive step forward for the exploration of novel microwave photonics experiments for quantum technology applications.

Project objective

Large multimode photonic quantum states are of paramount importance in the race to build a quantum computer and have been recently proposed as platforms for universal quantum computing. This class of quantum states has been experimentally demonstrated at the optical frequencies, but it is still not established in the microwave range, where one can take advantage of much higher non-linear interactions without introducing dissipation or dephasing. The aim of this proposal is to experimentally generate multimode quantum states of microwave photons with superconducting quantum circuits. The project aims at the control and characterization of quantum correlations between different frequency modes in microwave photons interacting with superconducting quantum devices. In order to reach this ambitious goal, non-linear processes in parametric Josephson devices will be explored. In particular, non-linear interactions will be engineered to generate multimode quantum correlations. This research will contribute to generate and manipulate very large multimode quantum states for the first time in the microwave regime. Controlling this kind of quantum states would represent a decisive step forward in the realisation of quantum information processing in the framework of Circuit Quantum Electrodynamics.
