Quantum coherence possible in incommensurate electronic systems
Researchers at the University of Illinois at Urbana-Champaign have demonstrated that quantum coherence is possible in electronic systems that are incommensurate, thereby removing one obstacle in the development of quantum devices. view more (2006-11-03)
Q is for quantum and 'Q-life'
As the world celebrates Charles Darwin, who was born 200 years ago, physicists can be forgiven a certain jealousy at the spotlight being placed on his profound legacy. view more (2009-07-08)
Carbon nanotubes outperform copper nanowires as interconnects
Researchers at Rensselaer Polytechnic Institute have created a road map that brings academia and the semiconductor industry one step closer to realizing carbon nanotube interconnects, and alleviating the current bottleneck of information flow that is limiting the potential of computer chips in everything from personal computers to portable music... view more...

Quantum dot lasers — 1 dot makes all the difference
Physicists at the National Institute of Standards and Technology (NIST) and Stanford and Northwestern Universities have built micrometer-sized solid-state lasers in which a single quantum dot can play a dominant role in the device's performance. view more (2007-04-13)
NIST demonstrates 'universal' programmable quantum processor
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated the first "universal" programmable quantum information processor able to run any program allowed by quantum mechanics-the rules governing the submicroscopic world-using two quantum bits (qubits) of information. view more (2009-11-16)
JQI researchers create entangled photons from quantum dots
To exploit the quantum world to the fullest, a key commodity is entanglement-the spooky, distance-defying link that can form between objects such as atoms even when they are completely shielded from one another. view more (2009-11-18)
Media Invitation: A chance to speak to those involved in the latest research in communications, photonics, electronics, software and networks.
Who is carrying out work to put humans into computers? Who is behind work to put computers into humans? How much faster will our computers be in the future? What is photomedicine? These are just some of the questions that will be answered at PREP 2002. This event is a showcase for the high quality work being carried out in UK universities in... view more... (2002-04-10)
The future of computing -- carbon nanotubes and superconductors to replace the silicon chip
The future of computing is under the spotlight at the Institute of Physics' Condensed Matter and Materials Physics conference at the Royal Holloway College of the University of London on 26-28 March. view more (2008-03-28)
Making strides in quantum dot infrared photodetectors
Researchers at Northwestern University have made significant strides in the development of quantum dot infrared photodetectors -- technology that may provide new imaging techniques with applications in medical and biological imaging, environmental and chemical monitoring, night vision and infrared imaging from space. view more (2007-05-18)
Nanoparticles + light = dead tumor cells
Medical physicists at the University of Virginia have created a novel way to kill tumor cells using nanoparticles and light. view more (2008-07-30)
Penn State Researchers Look Beyond the Birth of the Universe
According to Einstein's general theory of relativity, the Big Bang represents The Beginning, the grand event at which not only matter but space-time itself was born. view more (2006-05-15)
Engineering researchers: Supercomputer fastest of its type in world
A supercomputer named Novo-G described by its lead designer as likely the most powerful computer of its kind in the world became operational this week at the University of Florida. view more (2009-07-24)
EUROCORES conference gives cold quantum matter a European twist
Quantum matter has long fascinated the science community as many completely new physical phenomena have emerged from this field. Cold quantum matter can be used for applications such as high-precision clocks, which may run only one second behind per three million years! view more (2008-05-06)
Artificial atoms make microwave photons countable
Using artificial atoms on a chip, Yale physicists have taken the next step toward quantum computing by demonstrating that the particle nature of microwave photons can now be detected, according to a report spotlighted in the February 1 issue of the journal Nature. view more (2007-02-02)
'Strained' quantum dots show new optical properties
Quantum dots, tiny luminescent particles made of semiconductors, hold promise for detecting and treating cancer earlier. However, if doctors were to use them in humans, quantum dots could have limitations related to their size and possible toxicity. view more (2008-12-08)
New quantum dot transistor counts individual photons
A transistor containing quantum dots that can count individual photons (the smallest particles of light) has been designed and demonstrated at the National Institute of Standards and Technology (NIST). view more (2007-10-12)
Loopy photons clarify 'spookiness' of quantum physics
Researchers at the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (NIST/University of Maryland) have developed a new method for creating pairs of entangled photons, particles of light whose properties are interlinked in a very unusual way dictated by the rules of quantum physics. view more (2008-03-19)
Quantum Information Processing - Deciding the direction of research
Future developments in quantum information processing will radically change the way we store and process information. Its basic aim is to understand how the fundamental laws of quantum physics can be harnessed for the manipulation, storage and communication of information, opening up new possibilities in information processing. Research and... view more... (2002-08-16)
Laser tweezers sort atoms
Physicists of the University of Bonn have taken one more important hurdle on the path to what is known as a quantum computer: by using 'laser tweezers' they have succeeded in sorting up to seven atoms and lining them up. view more (2006-07-13)
Quantum decoys foil code-breaking attempts
Computer code-makers may soon get the upper hand on code-breakers thanks to a new quantum cryptography method designed at the University of Toronto. Quantum cryptography uses particles of light to share secret encryption keys relayed through fibre-optic communications. view more (2005-07-19)
