Quantum technology means the ability to organise and control the components of a functional system governed by the laws of quantum physics. The goal of this project is to train high-level young researchers through the development of innovative techniques to interface light and matter at the quantum level using atoms, nanostructures and photons, with applications in optics and quantum information processing. Well-trained and versatile researchers are needed to satisfy the demands of this rapidly growing field, in which there is also a strong drive and low threshold for industrial involvement. A prerequisite for success is the enhancement of the close connection between experimental, technological and theoretical studies. The proposed network, Light-Matter Interfaces for Quantum Enhanced Technology, LIMQUET, consists of seven academic and three industrial beneficiaries, complemented by one industrial partner. The academic partners are experienced but reasonably young groups with already established collaborations. The industrial partners have experience in developing and manufacturing high-quality components for research and industrial purposes. Within the Network, we anticipate highlights in (i) light-matter interfaces at the quantum level through the realisation of quantum networks using atoms, ions, and photons, (ii) the interfacing of light with light, in particular for light storage, (iii) adapting strategies originally developed in quantum optics to an integration into designed nanostructures, and (iv) the development of robust tools for quantum control and photonics. The training Network will enhance and use the synergy between the partners to produce a high-level doctoral training program in the field of quantum research and technology, including complementary skills and a pertinent impact of outreach activities. In order to enhance their career perspectives, all the ESRs will be jointly supervised and will be hosted on secondment by a company of the project.


The general scientific and technological objectives of LIMQUET are:

  • Develop robust tools for quantum technologies based on CQED, trapped ions and atoms, plasmonics; and transfer them to photonics
  • Interface ions and atoms with single photons using high-finesse optical cavities for quantum photonic network
  • Develop technology for high-fidelity single-photon production, detection and characterization
  • Explore novel schemes to couple light with light, mediated by matter
  • Implement a single photon quantum filter, a basic element required for quantum information processing
  • Achieve a strong single-emitter / photon coupling by surface plasmon polaritons at nanoscale dimensions
  • Implement photonic waveguides strongly coupled to emitters at nanoscale dimensions


The scheme below illustrates the interconnections between the scientific and technological Work Packages (WPs) of the LIMQUET project and features the main scientific outcomes and demonstration devices that will be produced in the course of the project.
