David Voss at APS Physics writes: ''Nonlocality—the entanglement of one object with another at a distance—is a powerful way to achieve quantum information processing. However, quantum mechanics is tethered by a “no-signaling” principle, that is, these correlations cannot be used to transmit information arbitrarily quickly from one point to another.
The recently founded Center for Optics and Photonics of the Universidad de Concepción, Chile, seeks to expand its theoretical, experimental and applied research activities in the fields of
- Experimental and theoretical Quantum Information Sciences
- Optical Traps (Optical Tweezers)
- Remote Sensing Technologies (DOAS, DIAL, LIDAR, Satellite Remote Sensing, Airborne based optical instrumentation)
We study the noise correlations of one-dimensional binary Bose mixtures, as a probe of their quantum phases. In previous work, we found a rich structure of many-body phases in such mixtures, such as paired and counterflow superfluidity. Here we investigate the signature of these phases in the noise correlations of the atomic cloud after time-of-flight expansion, using both Luttinger liquid theory and the time-evolving block decimation (TEBD) method. We find that paired and counterflow superfluidity exhibit distinctive features in the noise spectra.

US NSF Travel Grant Program for Nordita/Mittag-Leffler
Conference on Quantum Information Theory 4-8 Oct. 2010
This program will provide funds to support travel and lodging for US scientists to participate in the International Conference on Quantum Information Theory to be held in Stockholm Sweden during 4-8 October 2010. Information on the conference is available at http://agenda.albanova.se/conferenceDisplay.py?confId=1440

The school is intended to enable advanced graduate students or early post-docs to target the next step in their career. The idea is to provide a first step into new scientific topics and the associated techniques at the interface of Cold Atoms and Quantum Optics. Each scientific topic will be given at least 4 hours, of which 50% are dedicated to the techniques and real-world challenges. In addition we will offer perspectives in funding and careers beyond science in a set of hour-long lectures.
We offer 12 PhD positions at the Gdańsk University. This PhD project is organized by the Institute of Theoretical Physics and Astrophysics and the Institute of Experimental Physics.
The activities within the project include active participation in one of the research projects:
A number of many-body problems can be formulated using Hamiltonians that are quadratic in the creation and annihilation operators. Here, we show how such quadratic Hamiltonians can be efficiently estimated indirectly, employing very few resources. We find that almost all properties of the Hamiltonian are determined by its surface, and that these properties can be measured even if the system can only be initialised to a mixed state.
