These groups collaborated extensively in the framework of the QUANTIM project, and will contribute to the researches on WP1 - High-D temporal entanglement: quantum frequency combs , WP2 - High-D spatio-temporal entanglement: quantum X-waves , and WP4 - High-D temporal entanglement: quantum frequency combs .,
COMO theoretical group:
The group is internationally well known in the communities of Quantum Optics for pioneering contributions to
such fields as, e.g., optical bistability, squeezing and quantum imaging. The group has a well recognized
expertise in studying and modeling the properties of spatial and spatio-temporal fluctuations in quantum
optical systems, in particular in PDC, both in the cavity and travelling-wave configurations.
It is composed by:
COMO experimental group: Led by Paolo Di Trapani, it has developed an expertise in many areas of nonlinear optics, especially nonlinear optical solitons in quadratic and Kerr materials (visit the Virtual Institute for Nonlinear Optics - VINO web pages for more information). They have focused on quantum aspects of light propagation, especially the formation of quantum spatially-correlated images, leading to the first demonstration of quantum correlated image pairs in the high gain regime of parametric down conversion. The team is composed by
The USTRAT team is composed of a theoretical group at University of Strathclyde and an experimental
group at University of Glasgow. The groups have an excellent working
relationship and are formally connected by both being members of the Scotland-wide Scottish Universities
Physics Alliance (SUPA). They have collaborated in a large number of research projects including,
crucially, work on optical angular momentum and entanglement, which form an integral part of the current
USTRAT will contribute to the researches in WP1 - High-D temporal entanglement: quantum frequency combs, WP3 - High-D spatial entanglement (photon-pairs), and WP4 - High-D spatio-temporal entanglement: quantum X-waves.
USTRAT theoretical group: The theoretical Computational Nonlinear and Quantum Optics group at the University of Strathclyde has an undoubted international reputation for its many contributions to our understanding of non-classical light, pattern formation and to the study of optical angular momentum.
University of Glasgow: The experimental Optics Group at the University of Glasgow is internationally recognised for its contributions to the study and applications of optical angular momentum. These include pioneering studies of the mechanical effects of optical angular momentum and, more recently, experimental studies of quantum phenomena associated with optical angular momentum.
The Laboratoire Kastler-Brossel
is a joint research unit jointly run by Centre National de la Recherche
Scientifique, Ecole Normale Supérieure and Université Pierre et Marie Curie (UPMC). It is a large
research unit with 60 permanent scientists, 25 administrative and technical staff, and 40 visiting scientists
and postdocs. The quantum optics group led by Elizabeth Giacobino and Claude Fabre has a recognised
position in the study of quantum effects, such as squeezing and quantum correlations, in optical parametric
oscillators (OPOs) and atomic ensembles. It is running an experiment that detains the world record for twin
beams and EPR beams generation. LKB has performed various ultra-sensitive measurements below the
shot noise limit, using non-classical light. It has studied the quantum effects in semiconductor lasers and
microcavities, atomic ensembles, and single-photon sources using CdSe nanocrystals. Their most recent
studies mainly concerned the generation and use of quantum effects for the improvement of optical
measurements in images (where they were the first to produce quantum multimode light in the c.w. regime)
and to the realisation of quantum memories in atomic ensembles. Many of these researches were conducted
within different European programs (ESPRIT, FET-Open).
UPMC will contribute to the researches in WP1 - High-D temporal entanglement: quantum frequency combs, WP2 - High-D spatial entanglement (continuous variables), and WP5 - High-D entanglement of light and matter: quantum holograms.
Laboratoire de physique des lasers, atomes et molécules is a joint research unit jointly run by Centre National de la Recherche Scientifique and Université Des Sciences et Technologies de Lille (USTL). The theoretical group CNRS at PHLAM has a world-class expertise in theoretical quantum optics and quantum imaging. It will contribute to the researches in WP1 - High-D temporal entanglement: quantum frequency combs , WP2 - High-D spatial entanglement (continuous variables), and WP5 - High-D entanglement of light and matter: quantum holograms.
The UL team at Leiden University, led by Han Woerdman, runs an integrated experimental/theoretical program in quantum optics and quantum information. Topics addressed in the last decade are OAM of classical light, entanglement of fractional OAM degrees of freedom, quantum noise properties of semiconductor lasers, quantum chaos in open resonators, entanglement of surface plasmons, fractal properties of optical modes.

The UKBH partner is the experimental and theoretical quantum optics and quantum information groups
at the Niels Bohr Institute, University of Copenhagen. The groups constitute a major part of the
Danish Quantum Optics Center - QUANTOP.
The experimental activities focus on the realization of light-matter quantum interfaces using both room
temperature atomic vapor stored in glass cells as well as cold and ultracold atoms stored in optical dipole
traps and BEC. Researchers from the group have pioneered this field with research highlights including the
demonstration of entanglement of macroscospic objects and of a single (spatial) mode quantum memory.
On the theory side a new group was established in September 2004, led by associate professor Anders S.
Sørensen. This group is focussing on physical implementation of quantum information and in particular
quantum communication and quantum repeaters.
UKBH will contribute to the researches in WP1 - High-D temporal entanglement: quantum frequency combs, WP2 - High-D spatial entanglement (continuous variables) and WP5 - High-D entanglement of light and matter: quantum holograms .
USP is the theoretical quantum optics group at V.A.Fock Institute of Physics at St.Petersburg State
University. It has recognised results in the spectroscopy of intensity fluctuations in atomic non-linear
optics. An important contribution to the problem of natural fluctuations in lasers was provided by
elaborating the concept and theory of sub-Poissonian laser with regular excitation of working medium,
later realized experimentally by many laboratories. USP has pioneering results in the field of quantum
imaging and in the studies (in collaboration with Como and CNRS) of applications of spatially multimode
non-classical light fields to quantum information . USP has expertise in such modern problems of quantum
optics, as the theory of vertical-cavity surface-emitting semiconductor laser (VCSELs) and others.
USP will contribute to the researches in WP1 - High-D temporal entanglement: quantum frequency combs, WP2 - High-D spatial entanglement (continuous variables) and WP5 - High-D entanglement of light and matter: quantum holograms.
The ARC team already has successful projects in the quantum imaging and atom-light entanglement
fields as part of the Australian Research Council centre of excellence for Quantum-Atom Optics
(ACQAO) located at the Australian National University in Canberra , Australia led by Hans-A.Bachor and
Ping Koy Lam.
This group has excellent expertise in the design and operation of non-classical light sources, especially c.w. below threshold OPOs, in the generation of entangled light and in quantum information and communication, such as teleportation. Together with UPMC it has pioneered the field of spatial squeezing and sub-quantum-noise-limit spatial measurements with the experiments carried out at ARC.
ARC will contribute to the research activities in WP2 - High-D spatial entanglement (continuous variables) and WP5 - High-D entanglement of light and matter: quantum holograms.
