Study Provides Unprecedented Details On Ultrafast Processes In Diamond Nitrogen Vacancy Centers
2013-11-04 16:26:12

Lawrence Berkeley National Laboratory From supersensitive detections of magnetic fields to quantum information processing, the key to a number of highly promising advanced technologies may lie in one of the most common defects in diamonds. Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have taken an important step towards unlocking this key with the first ever detailed look at critical ultrafast processes in these...

A breakthrough in quantum cryptography demonstrates that information can be encrypted and then decrypted with complete security using the combined power of quantum theory and relativity - allowing the sender to dictate the unveiling of coded information without any possibility of intrusion or manipulation. Scientists sent encrypted data between pairs of sites in Geneva and Singapore, kept "perfectly secure" for fifteen milliseconds - putting into practice what cryptographers call a 'bit...

Like any task, there is an easy and a hard way to control atoms and molecules as quantum systems, which are driven by tailored radiation fields. More efficient methods for manipulating quantum systems could help scientists realize the next generation of technology by harnessing atoms and molecules to create small but incredibly powerful devices such as molecular electronics or quantum computers. Of course, controlling quantum systems is as painstaking as it sounds, and requires scientists...

Joint Quantum Institute Topology -- the understanding of how things are connected -- remains abstract, even with the popular example of doughnuts and coffee cups. This concept, esoteric as it appears, is also neat because it is the basis for creating ultrastable quantum "playgrounds."  In topological systems, certain quantum behaviors can be carefully probed and even harnessed for all kinds of practical applications—from metrology to electronics. Topological insulators, for instance,...

Google Uses qCraft To Teach Quantum Physics
2013-10-21 10:47:40

Michael Harper for redOrbit.com - Your Universe Online Google released a new mod for the popular building game Minecraft over the weekend which aims to teach players the most basic aspects of quantum physics. Called “qCraft,” the Google mod (modification) is less of a full-blown quantum physics simulator and more of a introductory course. While exploring in this new area of the video game, players can experiment with concepts like quantum entanglement, superposition and observer...

Nano-size Diamond Can Act As Efficient Optical Switch Controllable With Light
2013-10-15 13:41:01

ICFO-The Institute of Photonic Sciences A recent study led by researchers of the ICFO (Institute of Photonic Sciences) demonstrates that a single nano-diamond can be operated as an ultrafast single-emitter optical switch operating at room temperature. The scientific results of this study have been published in Nature Physics. Electronic transistors have become a key component to modern electronics, drastically improving the speed of information processing of current technologies. An...

A quantum computer can solve tasks where a classical computer fails. The question how one can, nevertheless, verify the reliability of a quantum computer was recently answered in an experiment at the University of Vienna. The conclusions are published in the reputed scientific journal Nature Physics. The harnessing of quantum phenomena, such as superposition and entanglement, holds great promise for constructing future supercomputers using quantum technology. One huge advantage of such...

Quantum Inverted Pendulum
2013-08-28 08:18:43

Georgia Institute of Technology A simple pendulum has two equilibrium points: hanging in the "down" position and perfectly inverted in the "up" position. While the "down" position is a stable equilibrium, the inverted position is definitely not stable. Any infinitesimal deviation from perfectly inverted is enough to cause the pendulum to eventually swing down. It has been known for more than 100 years, though, that an inverted pendulum can be stabilized by vibrating the pivot point....


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
