Workshop - Quantum coherence and correlations in condensed-matter and cold-atom systems

on 11-10-2014

... The workshop main aim is to generate a lively exchange of ideas between researchers working in the different but evertheless related fields of ultra-cold atoms, quantum information, superconductivity, and spintronics.

Quantum many-body systems show a variety of striking phenomena not observed in ensembles of classical particles. Quantum interference, quantum coherence, quantum entanglement and quantum statistics -
fermionic, bosonic or fractional - often conspire in producing
intricate many-particle states, including macroscopically coherent phases - Bose-Einstein condensation,
uperconductivity, charge- and spin-density waves, to name but a few. The spectacular effects seen in transport experiments, for instance in the Quantum Hall Effect, in
conductance quantization or in the Pauli blockade, also are related to the same quantum conspiracy. The aims of the workshop on "Quantum coherence and correlations in condensed-matter and cold-atom systems" will be both to elucidate the multiple facets of a very active field of research and to bridge the gaps between traditionally eparate topics.

Quantum communication via satellite based systems could enable quantum communications, such as Quantum Key Distribution, over truly global scales. Furthermore, they would allow us to perform quantum science experiments on entangled photons at scales and velocities not possible no the ground, which could be interesting in the quest towards understanding the boundary of quantum mechanics and space time. I will intrude the Canadian mission proposal called QEYSSAt (Quantum Encryption and Science Satellite) is considered as a possible microsatellite system, and will implement a quantum analyzer and detector in space. I will present our progress towards implementing a prototype of the payload, as well as ground based test and analysis of the expected performance for quantum communication between ground and space.
