Project description
Microwave photons and multimode correlations for quantum computing applications
Quantum optics harnesses the states of photons and the properties of quantum light involving multiple modes (e.g. spatial, temporal, frequency or polarisation). It offers the potential for large-scale quantum computing in which each mode represents an individual quantum state or degree of freedom. This type of system has been realised for photons in the visible frequency range but not in the microwave range which has numerous advantages for quantum computing. The EU-funded MOSAiC project is out to fill this gap with experimental generation of multimode quantum states of microwave photons in superconducting quantum circuits and subsequent control over quantum correlations.
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.
