Topological phases of matter possess intricate correlation patterns typically probed by entanglement entropies or entanglement spectra. In this Letter, we propose an alternative approach to assessing topologically induced edge states in free and interacting fermionic systems. We do so by focussing on the fermionic covariance matrix.

Place: 
Munich, Germany

Dear atom opticians, we would like to announce the 22nd Young Atom Opticians conference (YAO) to be held in Munich - on the Garching research campus - from Sunday, 21st to Friday, 26th of February 2016. The YAO conference is an international meeting aiming at PhD and Master students working in fields related to Quantum Optics and Atomic and Molecular Physics. It gained reputation as an excellent platform for young researchers to present their work and to establish networks among postgraduate researchers in the European atomic physics community.

Sending Quantum Messages Through Space

Summary: 

Fragile photon states useful for quantum communication can be faithfully transmitted and distinguished over a link between an orbiting satellite and a telescope on Earth.

Paolo Villoresi and colleagues at the University of Padova in Italy report [1] that photons—acting as carriers of quantum information—preserve their state, on which such information is encoded, even after having been reflected by satellites located more than a thousand kilometers away from Earth.
