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.

Breakthrough in Electron Spin Control Brings Quantum Computers Closer to Reality

Submitted by Shahram13 on Fri, 05/03/2010 - 15:47.

Researchers from two National Science Foundation (NSF)-funded Materials Research Science and Engineering Centers at Princeton University and the University of California, Santa Barbara made a significant breakthrough in the worldwide pursuit of quantum computing. They engineered a method to control the spin of a single electron within a magnetic field without disturbing other nearby electrons.

Second Workshop on Theory and Realisation of Practical Quantum Key Distribution

Dates: 
Sunday, June 13, 2010
Registration deadline: 
Thursday, April 29, 2010

The application for the second workshop on Theory and Realisation of Practical Quantum Key Distribution (TropicalQKD 2010), to be held at the Institute for Quantum Computing, University of Waterloo, Waterloo ON, Canada, is now open.

The workshop is devoted to all aspects of practical QKD, focussing on the latest developments in all its subfields. The workshop will bring together experimentalists and theoreticians who are interested in efficient and practical implementations of QKD.
