Physicists in Israel are the first to entangle five photons in a NOON state – the superposition of two extreme quantum states. Unlike previous schemes for creating such states, the researchers claim that their new technique can entangle an arbitrarily large number of photons – so called “high-NOON states”. This could be good news for those developing quantum metrology techniques because high-NOON states could be used to improve the precision of a range of different measurements.

We consider the question of how to distinguish quantum from classical transport through nanostructures. To address this issue we have derived two inequalities for temporal correlations in nonequilibrium transport in nanostructures weakly coupled to leads. The first inequality concerns local charge measurements and is of general validity; the second concerns the current flow through the device and is relevant for double quantum dots.

This event marks the end of the very successful Research Training Network EMALI funded by the EU. In addition to the presentation of results from EMALI work by the group of EMALI-trained fellows, confirmed speakers from outside the network are Jean Dalibard, Jeff Kimble and Andreas Wallraff. Furthermore, the program includes the following speakers, who are members of the network: Ennio Arimondo, Michael Fleischhauer, Atac Imamoglu, Giovanna Morigi, David Petrosyan, Eugene Polzik, Ferdinand Schmidt-Kaler, Nikolay Vitanov, Ian Walmsley, and Anton Zeilinger.

Our first CQD-DTC Summer School will be held in conjuction with the QuAMP Summer School organised by the division of Atomic, Molecular Optical and Plasma Physics of the Institute of Physics. The joint summer school will run from 31 August 2010 to 3 September 2010 (Financial support for the Summer School will be provided by the EPSRC).

This event marks the end of the EU FP6 STREP QICS on Foundational Structures in Quantum Computation and Information. It consists on extended tutorials on the main research strands within QICS, namely:

  • Structures and methods for measurement-based quantum computation
  • Categorical semantics, logics, diagrammatic methods
  • Classical-quantum interaction and information flow
  • Quantum automata, machines, calculi

The unavoidable presence of noise is thought to be one of the major problems to solve in order to pave the way for implementing quantum information technologies in realistic physical platforms. However, here we show a clear example in which noise, in terms of dephasing, may enhance the capability of transmitting not only classical but also quantum information, encoded in quantum systems, through communication networks.
