NanOQTech is a European Union Horizon 2020 project funded through the FET Open programme. Our goal is to build nanoscale hybrid quantum devices that strongly couple to light. To achieve that, we want to create solid-state nanostructures that exploit the uniquely narrow optical transitions of rare earth ions. Within the project, we expect these devices to lead to major advances in quantum communication, quantum sensing and quantum opto-electronics.

NanOQTech objectives are:

  • to develop rare earth nanostructures with long optical and spin coherences

  • to couple these structures to optical micro-cavities to demonstrate single-ion optical quantum memories, two-qubit gates and deterministic narrowband single photon sources at 1.5 µm 

  • to build hybrid RE-graphene devices to achieve plasmon mediated ion-ion interactions

  • to fabricate hybrid RE nano-resonators to reach the strong coupling regime

  • to guide the experimental effort and prepare further advances by developing comprehensive theoretical tools.

The project gathers 9 leading experimental and theoretical European teams. The expertise of the consortium includes inorganic chemistry, solid-state and atomic physics, quantum optics and information processing, nano-electronics and photonics and nano-mechanics. An industrial partner specialized in real-time signal processing and control also strengthens the consortium. The project's objectives are pursued in the following work packages (WP):

  • WP1: Nano-materials, optical micro-cavities and control systems

  • WP2: Spin-atom-photon interfaces

  • WP3: Opto-electrical and opto-mechanical hybrid systems

  • WP4: Management, dissemination and exploitation

NanOQTech started on October 1st, 2016 and will last for 3 years with a budget of 3.38 M€.
