Author Brida, G.; Genovese, M.; Ruo Berchera, I. openurl 
  Title Experimental realization of sub-shot-noise quantum imaging Type Journal Article
  Year 2010 Publication Nature Photonics Abbreviated Journal Nat. Photon.  
  Volume 4 Issue 4 Pages 227-230  
  Keywords (up) fromIPMRAS  
  Abstract The properties of quantum states have led to the development of new technologies, ranging from quantum information to quantum metrology. A recent field of research to emerge is quantum imaging, which aims to overcome the limits of classical imaging by making use of the spatial properties of quantum states of light . In particular, quantum correlations between twin beams represent a fundamental resource for these studies. One of the most interesting proposed schemes takes advantage of the spatial quantum correlations between parametric down-conversion light beams to realize sub-shot-noise imaging of weak absorbing objects, leading ideally to noise-free imaging. Here, we present the first experimental realization of this scheme, showing its potential to achieve a larger signal-to-noise ratio than classical imaging methods. This work represents the starting point for this quantum technology, which we anticipate will have applications when there is a requirement for low-photon-flux illumination (for example for use with biological samples).

Author Kok, Pieter openurl 
  Title Quantum optics: Entangled photons report for duty Type Journal Article
  Year 2010 Publication Nature Photonics Abbreviated Journal Nat. Photon.  
  Volume 4 Issue 8 Pages 504-505  
  Keywords (up) fromIPMRAS  
  Abstract Entangled photons are a key ingredient in optical quantum technologies, but researchers have so far been unable to produce a single pair of entangled photons. Now, two groups from China and Austria independently report just that, with a technique that avoids the need to infer entanglement from detection signatures.

Author Kono, Junichiro openurl 
  Title Coherent terahertz control Type Journal Article
  Year 2011 Publication Nature Photonics Abbreviated Journal Nat. Photon.  
  Volume 5 Issue Pages 5-6  
  Keywords (up) fromIPMRAS  
  Abstract Spin and charge terahertz excitations in solids are promising for implementing future technologies such as spintronics and quantum computation, but coherently controlling them has been a significant challenge. Researchers have now manipulated coherent spin waves in an antiferromagnet using the intense magnetic field of ultrashort terahertz pulses.
