We measure atom number statistics after splitting a gas of ultracold 87Rb atoms in a purely magnetic double-well potential created on an atom chip. Well below the critical temperature for Bose-Einstein condensation Tc, we observe reduced fluctuations down to -4.9  dB below the atom shot noise level.

First CHIST-ERA Joint Transnational Call
 

Call deadline: 5th of November 2010, 17:00 GMT

Matter wave interferometry experiments, levitated optomechanics, foundations of quantum physics

Scientists at the Max Planck Institute of Quantum Optics succeed in recording single-atom resolved images of a highly correlated quantum gas.

Physicists in Germany have used fluorescence imaging to identify individual particles in an optical lattice for the first time. The breakthrough could allow researchers to create more advanced simulations of quantum phenomena and it might help in the quest for practical quantum computing.

In the new Commission ICT Work Programme 2011-2012 there is a new call (with deadline December the 2nd 2010) for Coordination and Support Actions designed to identify FET-Flagship Candidate (if you don't know what a FET-Flagship is a good place to start from is here).

The Commission ICT Work-Programme 2011-2012 feature an interesting Objective under FET-Open, namely "Objective ICT-2011.9.4: International cooperation on FET research". This consist in a funding scheme that provides additional funding to existing grant for on-going FET IPs and STREPs ending at least 18 months after the submission date of the proposal (click on the tab below to access the full Objective text as published in the WP).

The new ICT Work Programme 2011-2012 has been published on the CORDIS website (a copy for download is available also here), and QIPC is contemplated again amongst the FET Proactive Initiatives. 

The WP features the objective ICT-2011 9.9 "Quantum ICT including ERA-NET Plus" (click on the tab below to read the full text)

On August 6 HP Labs' researcher Vinay Deolalikar sent the following letter to his fellows researchers in HP Labs:

"Dear Fellow Researchers,
I am pleased to announce a proof that P is not equal to NP, which is attached in 10pt and 12pt fonts

The proof required the piecing together of principles from multiple areas within mathematics. The major effort in constructing this proof was uncovering a chain of conceptual links between various fields and viewing them through a common lens. Second to this were the technical hurdles faced at each stage in the proof.

This work builds upon fundamental contributions many esteemed researchers have made to their fields. In the presentation of this paper, it was my intention to provide the reader with an understanding of the global framework for this proof. Technical and computational details within chapters were minimized as much as possible.
