Carefully fabricating nanofibers by heating and pulling may make for highly-efficient, optics-based, low-power atom traps WASHINGTON, June 17, 2014 /PRNewswire-USNewswire/ -- Take a fine strand of silica fiber, attach it at each end to a slow-turning motor, gently torture it over an unflickering flame until it just about reaches its melting point and then pull it apart. The middle will thin out like a piece of taffy until it is less than half a micron across -- about 200 times...

Joint Quantum Institute Sending entangled beams through fast-light materials Michael Lewis's bestselling book "Flash Boys" describes how some brokers, engaging in high frequency trading, exploit fast telecommunications to gain fraction-of-a-second advantage in the buying and selling of stocks. But you don't need to have billions of dollars riding on this-second securities transactions to appreciate the importance of fast signal processing. From internet to video streaming, we want...

What's so 'super' about this superfluid Atomtronics is an emerging technology whereby physicists use ensembles of atoms to build analogs to electronic circuit elements. Modern electronics relies on utilizing the charge properties of the electron. Using lasers and magnetic fields, atomic systems can be engineered to have behavior analogous to that of electrons, making them an exciting platform for studying and generating alternatives to charge-based electronics. Using a superfluid...

Global energy inequality lessens, but for how long? The 18th century writer Adam Smith provided a workable metaphor for the way society utilizes resources. In his book "The Wealth of Nations," he argued that even as individuals strive, through personal industry, to maximize their advantage in life, they inadvertently contribute---as if under the influence of a "hidden hand"---to an aggregate disposition of wealth. Well, if Smith were a physicist and alive in the 21st century he might be...

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,...

JQI lab sets a new record for creating heralded photons HERALDING Entanglement, by general consensus of physicists, is the weirdest part of quantum science. To say that two particles, A and B, are entangled means that they are actually two parts of an inseparable quantum thing. An important consequence of this inherent kinship is that measuring a property of A (say, the particle's polarization) is necessarily to know the corresponding property of B, even if you're not there with a...

Rubidium Vapor Stores Visual Images
2013-04-04 19:22:16

Lee Rannals for redOrbit.com — Your Universe Online Scientists have demonstrated how they are able to store visual images within a thin vapor of rubidium atoms. Scientists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland reported in the New Journal of Physics about how they used the cloud of atoms as an optical memory device. The team believes their work could be helpful in creating memory for quantum...

Reading Photons In Quantum Information Enters A New Phase
2013-01-07 07:44:51

redOrbit Staff & Wire Reports - Your Universe Online A new device developed by researchers at the Joint Quantum Institute (JQI) uses an active detection process to establish a new, more accurate standard for reading quantum information. "Decades ago communications theory established a minimal uncertainty for the accurate transmission and detection of information encoded in overlapping states. The hypothetical minimal detection error using conventional schemes is called the standard...

The storage of light-encoded messages on film and compact disks and as holograms is ubiquitous---grocery scanners, Netflix disks, credit-card images are just a few examples. And now light signals can be stored as patterns in a room-temperature vapor of atoms. Scientists at the Joint Quantum Institute have stored not one but two letters of the alphabet in a tiny cell filled with rubidium (Rb) atoms which are tailored to absorb and later re-emit messages on demand. This is the first time two...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
