Nanoscale Systems for Optical Quantum Technologies  

The Institut de Recherche de Chimie Paris (IRCP) coordinates NanOQTech and is in charge of material development. The Crystal and Quantum State Dynamics group at IRCP has extensive experience in the design, growth, characterization and modeling of rare-earth doped bulk or nanoscale crystals for applications in photonics, including optical information processing. In these materials, the IRCP team focuses on controlling the relaxation dynamics of optical and spin transitions. 

The Institut Néel is in charge of the nano-resonator hybrid systems in NanOQTech. The Institute is a leading laboratory in nanoscience. Within the Institute, the Nano-Optics and Force team specializes in optomechanics, hybrid quantum nanomechanical systems, nano-optics, and proximity forces measurements (Casimir forces, Atomic Force Microscopy and Magnetic Force Microscopy). 

The SYRTE Laboratory (Système de Référence Temps Espace – Space Time Reference System) is in charge of the optical measurements of the hybrid nano-resonators in NanOQTech. The laboratory is devoted to high precision measurement and modeling. It has extensive experience in ultra-high precision spectroscopic measurements, including state-of-the-art narrow-linewidth lasers both continuous waves and femtosecond (optical frequency combs). 

The quantum optics group at KIT is in charge of the spin-atom-photon interfaces using micro-cavities in NanOQTech. The group focuses on exploring applications of optical micro- and nano-cavities in the fields of quantum optics with solid-state systems, optical sensing, microscopy, and spectroscopy. The work builds on a particularly promising cavity design that relies on micro-machined optical fibres for experiments that include cavity-enhanced single photon sources, cavity-enhanced Raman spectroscopy of carbon nanotubes, cavity quantum electrodynamics with monolayer transition metal dichalcogenides, and cavity-enhanced microscopy.

The Quantum Photonics group at ICFO is in charge of the single photon source and will participate in the work on graphene photon-plasmon switch in NanOQTech. The group is active in experimental quantum optics and quantum information science. It has a strong experience in optical quantum memories and optical spectroscopy with rare-earth doped solids. The group also has a thorough expertise in quantum communication and in the creation, manipulation and characterization of quantum states of light and matter. 

The quantum nano-electronics group at ICFO is in charge of the hybrid RE-graphene devices in NanOQTech. The group studies fundamental nano-optoelectric properties of graphene and related 2D materials. The aim is to reveal new physical (quantum) phenomena related to strong interactions between light and matter, and to develop disruptive technologies in fields such as sensing, photodetection, nanoscale light switching, non-linear optics and light harvesting. 

The Quantum Information group at Lund University is in charge of the readout-qubit scheme and quantum gates in NanOQTech . The group has its core activities within the development of hardware for quantum computers and quantum memories based on rare-earth-ion doped inorganic crystals. 

AU is in charge of theoretical developments in NanOQTech. The scientific interests of the Aarhus node are varied, dealing with basic quantum optics and quantum information science in atomic systems and in hybrid atomic, superconducting, and solid-state spin systems. The group develops methods that address the precise quantum back-action effect on probed quantum systems, collective coupling schemes to atoms and spin ensembles, and the utilization of these effects for quantum information science. 

Keysight Technologies Inc. is the world's leading electronic test and measurement company, transforming today's measurement experience through innovation in wireless, modular, and software solutions. The Signadyne group, part of Keysight, will work closely with the scientific partners in NanOQTech to develop a state-of-the-art laser/cavity control system and further improve Keysight hardware execution technology. In addition, Keysight is the Exploitation Coordinator of the project.
