The Physikalisch-Technische Bundesanstalt (PTB) can now close this gap. (2009-11-06) Manipulating light on a chip for quantum technologies A team of physicists and engineers at Bristol University has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards long-sought-after quantum technologies, including super-powerful quantum computers and ultra-precise measurements. (2009-06-09) Memory with a twist: NIST develops a flexible memristor Electronic memory chips may soon gain the ability to bend and twist as a result of work by engineers at the National Institute of Standards and Technology (NIST). (2009-06-03) Sulphur in just one hair could blow a terrorist's alibi A group of researchers from the LGC Chemical Metrology Laboratory in the United Kingdom and the University of Oviedo, Spain, have come up with a method to detect how the proportions of isotopes in a chemical element (atoms with an equal number of protons and electrons but different numbers of neutrons) vary throughout the length of a single hair. (2009-05-28) Caltech physicists detect entanglement of one photon shared among four locations Scientists at the California Institute of Technology (Caltech) have developed an efficient method to detect entanglement shared among multiple parts of an optical system. (2009-05-11) Quantum paradox directly observed -- a milestone in quantum mechanics In quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experimentation and observed some of the 'spooky action of quantum mechanics' directly. (2009-03-04) Radioactivity: Discover the lowest amounts with new methods Detecting ever lower amounts of ionising radiation with ever better methods - sci-entists have had this goal since the start of the nuclear age. (2008-09-17) NIST studies how new helium ion microscope measures up Just as test pilots push planes to explore their limits, researchers at the National Institute of Standards and Technology (NIST) are probing the newest microscope technology to further improve measurement accuracy at the nanoscale. (2008-09-05) '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. (2008-08-29) New 'nano-positioners' may have atomic-scale precision Engineers have created a tiny motorized positioning device that has twice the dexterity of similar devices being developed for applications that include biological sensors and more compact, powerful computer hard drives.
