Using Photons to Manage Data
October 27, 2011 — Managing light to carry computer data, such as text, audio and video, is possible today with laser light beams that are guided along a fiber-optic cable. These waves consist of countless billions of ... > full story -
Quantum Computer Components 'Coalesce' to 'Converse'
October 26, 2011 — A team of physicists has shown for the first time how very different types of photons can be made to share "quantum state" information. Such unlike photon links are likely to be an important feature ... > full story -
Quantum Dots Cast Light on Biomedical Processes
October 26, 2011 — The light emitted by quantum dots is both more intense and longer lasting than that produced by the fluorescent markers commonly used in medical and biological applications. Yet these nano-scale ... > full story -
New Generation of Superlattice Cameras Add More 'Color' to Night Vision
October 20, 2011 — Recent breakthroughs have enabled scientists to build cameras that can see more than one optical waveband or "color" in the ... > full story -
One Clock With Two Times: When Quantum Mechanics Meets General Relativity
October 20, 2011 — General relativity, the joint theory of gravity, space and time gives predictions that become clearly evident on a cosmic scale of stars and galaxies. Quantum effects are fragile and observed on ... > full story -

Step Toward Quantum Computers: Using Commercial Photonic Components
October 18, 2011 — Researchers in Spain have developed a model that provides the basis for the application of commercial photonic components to the field of quantum computers and quantum ... > full story -
Impurity Atoms Introduce Waves of Disorder in Exotic Electronic Material
October 17, 2011 — Scientists reveal how substituting just a few atoms can cause widespread disruption of the delicate electron interactions that give a particular "heavy fermion" material its unique properties, ... > full story -
Nano Funnel Used to Generate Extreme Ultraviolet Light Pulses
October 17, 2011 — Scientists have successfully concentrated the energy of infrared laser pulses using a nano funnel enabling them to generate extreme ultraviolet light pulses, which repeated 75 million times per ... > full story -
A Hidden Order Unraveled: Microscopic Views on Quantum Fluctuations
October 14, 2011 — Fluctuations are fundamental to many physical phenomena in our everyday lives. Using a high resolution microscope, scientists have now been able to image quantum-correlated particle-hole pairs in a ... > full story -
Mobile Electrons Multiplied in Quantum Dot Films
October 14, 2011 — Researchers have demonstrated that several mobile electrons can be produced by the absorption of a single light particle in films of coupled quantum dots. These multiple electrons can be harvested in ... > full story
