Quantum optics work wins physics Nobel
STOCKHOLM – Separate but related quantum optics technologies – ions in a harmonic trap and photons in a cavity – that allow the measurement and control of individual quantum systems were recognized by the Royal Swedish Academy of Sciences with the 2012 Nobel Prize in physics. Serge Haroche of the Collège de France and Ecole Normale Supérieure in Paris and David J. Wineland of the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder will...
Quantum Optics Work Wins Physics Nobel
STOCKHOLM, Oct. 9, 2012 — Separate but related quantum optics technologies — ions in a harmonic trap and photons in a cavity — that allow the measurement and control of individual quantum systems were recognized Tuesday by the Royal Swedish Academy of Sciences...
Circuit Sets Record Beating Microscopic Drum
BOULDER, Colo., March 21, 2011 — An electrochemical circuit in which microwaves communicate with a vibrating mechanical component 1000 times more vigorously than has previously been demonstrated could one day control the motion of large objects at the quantum scale. ...
Quantum cloning: Radiometry on a small scale
GENEVA – Measuring the luminous power of light is a basic task in physics laboratories and telecom applications. Until recently, however, measuring light energy in an absolute manner has required the complex equipment and techniques available only in...
Quantum Random Number Generator Service Begins
BERLIN, Dec. 2, 2010 — PicoQuant GmbH and Nano-Optics groups at the Department of Physics of Humboldt University Berlin announced they have started a Quantum Random Number Generator (QRNG) that is based on the quantum randomness of photon arrival times. The...
Atomic Behavior Recorded in Real Time
SAN JOSE, Calif., Sept. 24, 2010 — IBM announced a breakthrough to its 20-year-old scanning tunneling microscope technology on Friday that gives scientists the ability to record, study and visualize the extremely fast spin of electrons inside individual atoms, in real time. Similar...
Electron-Multiplying CCD for Lidar Applications
Aug 1, 2010 — Until recently, only photomultiplier tubes were suitable for low-light imaging. However, this technology and associated poor spatial resolution were not suited to scientific applications. Solid-state devices such as image intensifiers or...
Coherent, SiOnyx Partner to Develop Black Silicon
SANTA CLARA, Calif., May 5, 2010 — Coherent Inc. and SiOnyx Inc. announced they will partner to evaluate and develop SiOnyx's black silicon material for solar applications. Black silicon offers a number of advantages for the solar industry, including reduction of cost, an increase in...
UK, China Fund Spintronics Study
Jul 2, 2009 — A team of researchers from the University of Surrey and two other institutions have been awarded a grant of around £430,000 (about $704,000) to develop prototype ultrasmall-scale silicon structures for "spintronic" semiconductors. Jointly awarded by...
CLEO/IQEC to Feature Strong Market Focus
BALTIMORE, April 22, 2009 – More than 1200 technical presentations, 39 short courses, seven symposia, more than 100 prominent invited speakers, the PhAST Market Focus, a job fair and career workshop and 350 companies exhibiting at PhotonXpo are among the highlights of the...
Quantum communication, without – and with – delay
GAITHERSBURG, Md. – When it comes to computing, some of the lessons we learned in kindergarten really do apply. Algorithms have to take turns. Otherwise, final calculations could be wrong. Such data flow control is done routinely in standard computers. Now the...
Light Drives Nanomachines
NEW HAVEN, Conn., Nov. 26, 2008 -- By combining two emerging fields -- nanophotonics and nanomechanics -- researchers have shown that the force of light can be harnessed to drive machines at the nanoscale. Nanophotonics and nanomechanics make possible the extreme miniaturization...
Quantum Gases Made Visible
MAINZ, Germany, Oct. 22, 2008 – Scientists at the Johannes Gutenberg University Mainz have, for the first time, succeeded in rendering the spatial distribution of individual atoms in a Bose-Einstein condensate visible. Bose-Einstein condensates are small, ultracold gas clouds...
Show Bigger, Even Better
SAN JOSE, Calif., Oct. 22, 2008 -- Four renowned symposia featuring the presentations of 3275 research papers by the brightest minds in the photonics industry, 85 conferences, 75 courses, 1100 exhibitors and a special two-day Career Fair are expected to make SPIE Photonics West 2009...

Sensor Peers into Electrons
CAMBRIDGE, Mass., Oct. 1, 2008 -- Physicists have exploited a special "flaw" in diamond crystals, manipulating them into monitoring magnetic signals from individual electrons and atomic nuclei and allowing scientists to spy on some of the universe's tiniest building blocks. The...
Physicists Get Genius Grants
CHICAGO, Sept. 23, 2008 -- An optical physicist who demonstrated that power can be transmitted wirelessly, a physicist who explores the mysterious behavior of quantum systems, and an astrophysicist working to improve the spatial resolution and precision of instruments used to...
'Squeezed Light' Record Set
HANOVER, Germany, Jan. 29, 2008 -- An extremely high-quality green laser beam has allowed a record number of photons to be placed in a specific order for use in gravitational wave detectors. Ordering the photons reduced fluctuations in the intensity of the light by 90 percent. This...
Radio Waves Cool Cantilever
BOULDER, Colo., Sept. 17, 2007 -- Physicists have used radio waves to dampen the motion of a thin silicon cantilever containing more than a quadrillion atoms, a cooling technique that has the potential to demonstrate quantum behavior in a macroscopic object using smaller and simpler...
New Zealand Invests in Tech
WELLINGTON, New Zealand, July 19, 2007 -- New Zealand is investing NZ$628 million (about $498 million) in new research programs in an effort to position the country at the forefront of nanotechnology development and the production of new supermaterials, a government funding agency announced...
Atomic Spectroscopy Achieved with Optics on a Chip
SANTA CRUZ, Calif., June 1, 2007 -- Atomic spectroscopy has been performed with integrated optics on a chip for the first time by guiding a beam of light through a rubidium vapor cell integrated into a semiconductor chip. Atomic spectroscopy is a widely used technique with diverse...
