Carbon-based quantum dots could mean 'greener' safer technology in medicine and biology
Chemists at Clemson University say they have developed a new type of quantum dot that is the first to be made from carbon.   view more (2006-05-24)

NIST photon detectors have record efficiency
Sensors that detect and count single photons, the smallest quantities of light, with 88 percent efficiency have been demonstrated by physicists at the National Institute of Standard and Technology (NIST).   view more (2005-06-02)

Tossing a coin in the microcosm
When you toss a coin, you either get heads or tails. By contrast, things are not so definite at the microcosmic level. An atomic 'coin' can display a superposition of heads and tails when it has been thrown.   view more (2009-07-10)

Small nanoparticles bring big improvement to medical imaging
If you're watching the complex processes in a living cell, it is easy to miss something important-especially if you are watching changes that take a long time to unfold and require high-spatial-resolution imaging.   view more (2009-11-18)

Physicists team up to learn how quantum mechanical states break down
Researchers at the US Department of Energy's Ames Laboratory, the University of California, Santa Barbara, and Microsoft Station Q have made significant advancements in understanding a fundamental problem of quantum mechanics -- one that is blocking efforts to develop practical quantum computers with processing speeds far superior to conventional... view more...

First tunable, 'noiseless' amplifier may boost quantum computing, communications
Researchers at the National Institute of Standards and Technology (NIST) and JILA, a joint institute of NIST and the University of Colorado (CU) at Boulder, have made the first tunable "noiseless" amplifier.   view more (2008-10-16)

Atom 'noise' may help design quantum computers
As if building a computer out of rubidium atoms and laser beams weren't difficult enough, scientists sometimes have to work as if blindfolded: The quirks of quantum physics can cause correlations between the atoms to fade from view at crucial times.   view more (2007-03-05)

New imaging technique reveals the atomic structure of nanocrystals
A new imaging technique developed by researchers at the University of Illinois overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom (less than one hundred-millionth of a centimeter).   view more (2009-02-19)

University of Cincinnati researchers create all-electric spintronics
A multidisciplinary team of UC researchers is the first to find an innovative and novel way to control an electron's spin orientation using purely electrical means.   view more (2009-10-28)

University of Oklahoma Researchers Discover Giant Rydberg Atom Molecules
A group of University of Oklahoma researchers led by Dr. James P. Shaffer, Homer L. Dodge Department of Physics and Astronomy, have discovered giant Rydberg molecules with a bond as large as a red blood cell.   view more (2009-06-25)

Tiny avalanche photodiodes target bioterrorism agents
After the anthrax attacks in the United States in 2001 the threat of a larger and more deadly bioterrorism attack - perhaps from smallpox, plague or tularemia - became very real. But the ability to detect such biological agents and rapidly contain an attack is still being developed.   view more (2005-09-14)

'Racetrack' for fast electrons in semiconductor structures
In order to realize the electrical units of voltage, resistance and current with highest accuracy quantum effects in nano-circuits are nowadays used. Important prerequisites are extremely pure semiconductor layers where high-mobile electrons move through the crystal without collision with residual impurities.   view more (2008-08-29)

Atoms don't dance the 'bose nova'
Hanns-Christoph Naegerl's research group has investigated how ultracold quantum gases behave in lower spatial dimensions. They successfully realized an exotic state, where, due to the laws of quantum mechanics, atoms align along a one-dimensional structure.   view more (2009-09-04)

Code for unbreakable quantum encryption generated at record speed over fiber
Raw code for 'unbreakable' encryption, based on the principles of quantum physics, has been generated at record speed over optical fiber at the Commerce Department's National Institute of Standards and Technology (NIST).   view more (2006-04-19)

The Max-Planck Research Prize 2003 rewards an INTAS grantee
INTAS is pleased to congratulate Prof. Klaas Bergmann who, on 26 November 2003, as well as 11 other scientists from Germany, United States, Israel and Canada, won a Max-Planck Research Prize 2003 (Max Planck Forschungspreis fuer Internationale Kooperation 2003). This prize rewards a scientist who carried out, with his co-workers at the University... view more... (2003-12-16)

A Single-Photon Server with Just One Atom
Every time you switch on a light bulb, 10 to the power of 15 (a million times a billion) visible photons, the elementary particles of light, are illuminating the room in every second. If that is too many for you, light a candle.   view more (2007-03-13)

New quantum state: two electrons trapped in an excited atom
Researchers from Universitat Autònoma de Barcelona and the University of Salamanca have discovered a method to generate a new quantum phenomenon which had never been explored until now: simultaneous trapping of two particules between two excited energy states. The research, reported in Physical Review Letters may have important applications... view more... (2002-01-23)

NIST physicists demonstrate quantum entanglement in mechanical system
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated entanglement-a phenomenon peculiar to the atomic-scale quantum world-in a mechanical system similar to those in the macroscopic everyday world.   view more (2009-06-04)

NIST develops novel ion trap for sensing force and light
Miniature devices for trapping ions (electrically charged atoms) are common components in atomic clocks and quantum computing research. Now, a novel ion trap geometry demonstrated at the National Institute of Standards and Technology (NIST) could usher in a new generation of applications because the device holds promise as a stylus for sensing... view more...
