quantum computing

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.

Quitemad is a consortium of five groups working in different aspects of QIPC in the region of Madrid. This project is a four year coordinated action funded by the regional goverment. Apart from research in technological and theoretical aspects of of quantum information theory, the consortium is strongly devoted to the development of a four year program of activities, such as workshops, conferences, seminars and scientific exchange between local and international groups.

Levitin and Toffoli have published a paper that is best summed up by the final sentence of the abstract: "These results establish the fundamental quantum limit on the rate of operation of any information-processing system". News article here and paper on arXiv here

Quantum cryptography is a promising new way to send encrypted information. This new technology does suffer from some drawbacks. One of the toughest problems is the range that information can be sent is limited to around 50-100 km. Advancements have been underway. The most promising advancement is being working on by a team based out of the Australian National University. They found a way to store and manipulate photons to be used as a memory device.

Post-Doctoral fellowships at the Institute for Quantum Computing

The Institute for Quantum Computing is inviting applications for postdoctoral positions in all aspects of quantum information processing, bridging areas from fundamental theory to physical implementations.
