Scientists demonstrate laser with controlled polarization
Applied scientists at the Harvard School of Engineering and Applied Sciences (SEAS) in collaboration with researchers from Hamamatsu Photonics in Hamamatsu City, Japan, have demonstrated, for the first time, lasers in which the direction of oscillation of the emitted radiation, known as polarization, can be designed and controlled at will. view more (2009-04-13)
Optoelectronics Research Centre director awarded CBE
Professor David Payne, Director of the University of Southampton's Optoelectronics Research Centre (ORC), has been appointed a Commander of the Order of the British Empire (CBE) in the Queen's Birthday Honours announced on Saturday (12 June). Professor Payne has been recognised for his services to photonics. Professor Payne is an internationally... view more... (2004-06-14)
Helia Wraps-up Optical Coatings
A new Scottish multi-million pound photonics company is geared up for the future of telecommunications after securing a seven figure private investment deal. The investment has allowed Helia Photonics Ltd, a Heriot-Watt University spin-out to purchase the coatings division of Terahertz Photonics in a technology transfer deal, and say they are... view more...

Scientists demonstrate all-fibre quantum logic
A team of physicists and engineers have demonstrated all-fibre quantum logic, where single photons are generated and used to perform the contolled-NOT quantum logic gate in optical fibres with high fidelity. view more (2009-05-29)
Silicon chips for optical quantum technologies
A team of physicists and engineers has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards the long sought after goal of a super-powerful quantum computer. view more (2008-03-28)
Hackers beware! New technique uses photons, physics to foil codebreakers
For governments and corporations in the business of transmitting sensitive data such as banking records or personal information over fibre optic cables, a new system demonstrated by University of Toronto researchers offers the protective equivalent of a fire-breathing dragon. view more (2006-02-23)
Quantum ghosts are helpful
The idea that far distant particles can somehow 'talk' to each other worried Einstein so much that he called it 'spooky action at a distance'. view more (2009-04-28)
The fight for the best quantum bit (qubit)
Our results give us, for the first time, the possibility to understand the interaction between just two electrons placed next to each other in a carbon nanotube. view more (2008-06-25)
Magnets in a spin bath
Is quantum mechanics relevant to everyday life? Latest scientific evidence suggests that it is. A paper published in Science based on research from the Paul Scherrer Institute (PSI) in Switzerland and others, reports how quantum computers behave as if they are isolated devices. The extent to which they do this can be regulated by the environment... view more... (2005-04-15)
Quantum memory and turbulence in ultra-cold atoms
Scientists at MIT have figured out a key step toward the design of quantum information networks. view more (2009-07-20)
Experiments at UCSB push quantum mechanics to higher levels
Scientists at UC Santa Barbara have devised a new type of superconducting circuit that behaves quantum mechanically -- but has up to five levels of energy instead of the usual two. The findings are published in the August 7 issue of Science. view more (2009-08-12)
Scientists demonstrate highly directional semiconductor lasers
Applied scientists at Harvard University in collaboration with researchers from Hamamatsu Photonics in Hamamatsu City, Japan, have demonstrated, for the first time, highly directional semiconductor lasers with a much smaller beam divergence than conventional ones. The innovation opens the door to a wide range of applications in photonics and... view more... (2008-07-28)
New Law for Quantum Computers Disclosed
Arun Kumar Pati, who is currently at the University, but who is based at the Bhaba Atomic Research Centre, Mumbai, India, and Samuel L. Braunstein, at the School of Informatics have published a paper in the current issue of the International Journal, Nature [9 March 2000], describing their discovery of a new law, which they call the quantum... view more...

A tiny, tunable well of light, and a string theorist's toolbox
Photonics, the science of using photons to carry information, promises to continue improving a wide variety of technologies, from computing to high-speed communication. view more (2009-09-21)
NIST demonstrates better memory with quantum computer bits
Physicists at the National Institute of Standards and Technology (NIST) have used charged atoms (ions) to demonstrate a quantum physics version of computer memory lasting longer than 10 seconds-more than 100,000 times longer than in previous experiments on the same ions. view more (2005-08-11)
New Journal of Physics Quantum Cryptography Focus Issue
Real advances in quantum cryptography are described today, 12 July 2002, in a special issue of New Journal of Physics, published jointly by the Institute of Physics and the German Physical Society. Electronic transfer of information is vulnerable to attack by "eavesdroppers", hence the use of encryption techniques. Underlying nearly all forms of... view more... (2002-07-10)
Computing breakthrough could elevate security to unprecedented levels
By using pulses of light to dramatically accelerate quantum computers, University of Michigan researchers have made strides in technology that could foil national and personal security threats. view more (2007-08-17)
Ancient neutrinos could put string theory and quantum loop gravity to the test
Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales. view more (2005-10-14)
