Description du projet
Photons micro-ondes et corrélations multimodes pour des applications d’informatique quantique
L’optique quantique exploite les états des photons et les propriétés de la lumière quantique impliquant des modes multiples (par exemple, spatial, temporel, fréquence ou polarisation). Elle offre le potentiel d’une informatique quantique à grande échelle dans laquelle chaque mode représente un état quantique individuel ou un degré de liberté. Ce type de système a été mis au point pour des photons dans la gamme de fréquences visibles, mais pas dans la gamme des micro-ondes, qui présente pourtant de nombreux avantages pour l’informatique quantique. Le projet MOSAiC, financé par l’UE, entend combler cette lacune en générant expérimentalement des états quantiques multimodes de photons micro-ondes dans des circuits quantiques supraconducteurs et en contrôlant ensuite les corrélations quantiques.
Objectif
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.
