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...

University of Innsbruck Even computers are error-prone. The slightest disturbances may alter saved information and falsify the results of calculations. To overcome these problems, computers use specific routines to continuously detect and correct errors. This also holds true for a future quantum computer, which will require procedures for error correction as well: "Quantum phenomena are extremely fragile and error-prone. Errors can spread rapidly and severely disturb the computer," says...

Alan McStravick for redOrbit.com - Your Universe Online The difficulty in understanding the field of quantum computing just got a little easier, but only slightly. New research from the University of Waterloo's Institute for Quantum Computing has confirmed, at least theoretically, that the concept of contextuality is a necessary resource required for achieving the advantages of quantum computation. Contextuality is regarded as one of the weirder aspects of quantum theory and is a...

Quantum Teleportation Experiments Hailed A Success
2014-06-02 04:50:22

Alan McStravick for redOrbit.com - Your Universe Online The world of Gene Roddenberry has given us so many things that seemed an impossibility when we first saw them on the fantastical science-fiction television show Star Trek. All you need do is visit your local grocery store for the sliding doors triggered by an electronic eye, or reach into your own pocket for a personal communications device. The one thing that seemed too impossible, however, was the transporter, a teleportation...

Superconducting Qubit Array Points The Way To Quantum Computers
2014-04-24 03:15:00

Julie Cohen, UC Santa Barbara A new five-qubit array from UCSB’s Martinis Group is on the threshold of making a quantum computer technologically feasible to build A fully functional quantum computer is one of the holy grails of physics. Unlike conventional computers, the quantum version uses qubits (quantum bits), which make direct use of the multiple states of quantum phenomena. When realized, a quantum computer will be millions of times more powerful at certain computations than...

Quantum Computing Advances At MIT - Trapping Rubidium Atoms In A Lattice Of Light
2014-04-11 04:29:35

redOrbit Staff & Wire Reports - Your Universe Online Scientists at MIT and Harvard University have developed a light lattice that traps atoms, a technique they say could aid in the creation of powerful quantum computing systems. The researchers used a laser to place individual atoms of the metal rubidium near the surface of a lattice of light, allowing them to couple a lone atom with a single photon, or light particle. The system allows both the atom and photon to switch the quantum...

Brake For Spinning Molecules
2014-03-13 15:39:05

Max Planck Institute The precise control of the rotational temperature of molecular ions opens up new possibilities for laboratory-based astrochemistry Chemical reactions taking place in outer space can now be more easily studied on Earth. An international team of researchers from the University of Aarhus in Denmark and the Max Planck Institute for Nuclear Physics in Heidelberg, discovered an efficient and versatile way of braking the rotation of molecular ions. The spinning speed of...

Cryptography Scheme Secured By Quantum Physics
2014-03-12 14:30:34

Centre for Quantum Technologies The way we secure digital transactions could soon change. An international team has demonstrated a form of quantum cryptography that can protect people doing business with others they may not know or trust – a situation encountered often on the internet and in everyday life, for example at a bank's ATM. "Having quantum cryptography to hand is a realistic prospect, I think. I expect that quantum technologies will gradually become integrated with existing...
