All questions answered by Prof. Alberto Bramati from Sorbonne Université, France.
What do you want to achieve in this project?
The aim of the PhoQuS project is to develop a novel platform for quantum simulation, based on photonic quantum fluids, realised in different photonic systems with suitable non-linearities, allowing to engineer an effective photon-photon interaction. The main objectives of this project are to fully understand the superfluid and quantum turbulent regimes for quantum fluids of light and to achieve simulations of systems of very different nature, ranging from condensed matter to astrophysics.
How will European citizens benefit from this project, both from the technology developments it accomplishes as well as the basic science breakthroughs it may achieve?
The PhoQuS approach merges the theoretical and experimental techniques of controlled manipulation of quantum systems (photons) with many-body and quantum field physics. The project is based on fundamental physics and will have an impact on fundamental science (quantum optics, solid state physics, cosmology, quantum gravity) and quantum technologies (quantum simulations).
The expected impact will be the enhancement of cross-disciplinary studies involving optics, general relativity, quantum field theory and solid state physics. This will lead to a deeper understanding of quantum field theories and to the development of novel concepts for the control of quantum states to be harnessed in future quantum architectures.
Why is the Quantum Flagship important and why did you choose to become part of it?
The Quantum Flagship is an unprecedented opportunity for the researchers working on quantum physics and related fields to fuel collaborative work between high-risk visionary research and technology. The economical effort deployed by the European Commission is one of the most significant of the last years for these topics and it should allow establishing the basis of the “quantum revolution” with strong potential impact on the daily life. To be part of this adventure is of course extremely exciting and motivating.
How do you see the advancement of quantum technologies in the near future and what would be your ultimate dream in the long run?
A number of “quantum demonstrators” and prototypes should be developed in the next years, boosted by the Quantum Flagship initiative. In the long run, hopefully, fully quantum devices for computing, simulation, metrology and sensing will be realised.
