Project description
Research leverages photon interactions for quantum simulations
Quantum simulators enable scientists to gain further insight into physical problems by emulating effects that are too difficult for classical computers to simulate. Experiments involving ultracold atoms and trapped ions are typical examples of quantum simulator applications. The EU-funded PhoQuS project plans to develop a new platform for quantum simulations based on photonic quantum fluids. By merging theoretical and experimental techniques of controlled manipulation of quantum systems (photons) with many-body and quantum field physics, the project aims to enhance understanding of the superfluid and turbulent nature of light waves. Project results will have implications for fundamental science – from condensed matter physics and quantum optics to astrophysics.
Objective
Quantum simulation is an emerging and exciting field for which several systems, such as ultracold-atoms, trapped ions or superconducting circuits are being actively investigated. In this project we aim to develop a novel platform for quantum simulation, based on photonic quantum fluids. Quantum fluids of light can be realised in different photonic systems with suitable nonlinearities, allowing to engineer an effective photon-photon interaction. The photon-photon interaction necessary to form a superfluid is provided by the optical nonlinearity of the medium. We will first fully characterize the superfluid and quantum turbulent regimes for quantum fluids of light, investigating the propagation in optically controlled landscapes with the demonstration of important milestones such as many-body localization and the superfluid to Mott–insulator transition. Based on these achievements and on the unprecedented flexibility offered by the all- optical control in quantum fluids of light, we will implement quantum simulations and simulate systems of very different nature, ranging from astrophysics to condensed matter. Fundamental open questions such as superconductivity, black hole physics, and quantum gravity will be addressed within the photon fluid platform.
