In tiny supercooled clouds, physicists exchange light and matter
Physicists have for the first time stopped and extinguished a light pulse in one part of space and then revived it in a completely separate location. view more (2007-02-08)
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)
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)
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)
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)
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)
Photon-transistors for the supercomputers of the future
Scientist from the Niels Bohr Institute at University of Copenhagen and from Harvard University have worked out a new theory which describe how the necessary transistors for the quantum computers of the future may be created. The research has just been published in the scientific journal Nature Physics. view more (2007-08-27)
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)
Up-scale: Frequency converter enables ultra-high sensitivity infrared spectrometry
In what may prove to be a major development for scientists in fields ranging from forensics to quantum communications, researchers at the National Institute of Standards and Technology (NIST) have developed a new, highly sensitive, low-cost technique for measuring light in the near-infrared range. view more (2009-08-27)
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)
New ion trap may lead to large quantum computers
Physicists at the National Institute of Standards and Technology (NIST) have designed and built a novel electromagnetic trap for ions that could be easily mass produced to potentially make quantum computers large enough for practical use. view more (2006-07-07)
Quantum computing spins closer
The promise of quantum computing is that it will dramatically outshine traditional computers in tackling certain key problems: searching large databases, factoring large numbers, creating uncrackable codes and simulating the atomic structure of materials. view more (2008-11-24)
'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)
Discovery of 'hidden' quantum order improves prospects for quantum super computers
An international team of scientists, including several at The Johns Hopkins University, has detected a hidden magnetic "quantum order" that extends over chains of nearly 100 atoms in a material that is otherwise magnetically disordered. view more (2007-07-27)
Physics breakthrough much ado about 'nothing'
How do scientists store nothing? It may sound like the beginning of a bad joke, but the answer is causing a stir in the realm of quantum physics after two research teams, including one from the University of Calgary, have independently proven it's possible to store a special kind of vacuum in a puff of gas and then retrieve it a split second later. view more (2008-03-06)
