Transfer Of Flying Quantum Bits At The Touch Of A Button
2013-08-15 10:40:22

Johannes Gutenberg Universitaet Mainz Hybrid technology makes possible highly reliable transmission of photonic qubits By means of the quantum-mechanical entanglement of spatially separated light fields, researchers in Tokyo and Mainz have managed to teleport photonic qubits with extreme reliability. This means that a decisive breakthrough has been achieved some 15 years after the first experiments in the field of optical teleportation. The success of the experiment conducted in Tokyo...

Beam Me Up Scotty: Physicists Calculate Energy Needed For Teleportation
2013-07-30 13:53:26

Lee Rannals for redOrbit.com - Your Universe Online Physics students have determined what energy it would take in order for the fictional Star Trek character Scotty to beam up Captain Kirk. Four University of Leicester physics students published a paper in the School's Journal of Physics Special Topics explaining that the energy required to teleport one person is shown to be dependent on bandwidth, meaning a decrease in time creates an increase in power consumption. In order for a...

Researchers Develop Quantum Teleportation Between Gas Atoms
2013-06-06 15:31:14

Brett Smith for redOrbit.com - Your Universe Online Researchers from the Niels Bohr Institute have announced the capacity to consistently teleport information between two clouds of gas atoms, according to a report in the journal Nature Physics. "It is a very important step for quantum information research to have achieved such stable results that every attempt will succeed," said co-author Eugene Polzik, professor at the Niels Bohr Institute at the University of Copenhagen. In their...

BURNABY, British Columbia and PALO ALTO, Calif., May 22, 2013 /PRNewswire/ -- D-Wave Systems Inc., the world's first commercial quantum computing company, today announced the publication of a peer-reviewed paper entitled "Thermally assisted quantum annealing of a 16-qubit problem" in the journal Nature Communications. The paper presents the results of the first experimental exploration of the effect of thermal noise on quantum annealing. Quantum annealing is the process by which qubits, the...

Researchers Believe Quantum Satellites Will Be The Next Space Race
2013-03-01 20:16:16

Lee Rannals for redOrbit.com — Your Universe Online Two researchers from the University of Waterloo, Canada say the next big space race is building the first global quantum-communication satellite network. Up until now, the furthest quantum-communication signals have traveled is just a few hundred miles. However, this technology is up-and-coming, and is what Thomas Jennewein and Brendon Higgins believe will be driving the next space race. Quantum communication is the science...

Recycling In The Quantum World Could Lead To Better Teleportation

Alan McStravick for redOrbit.com - Your Universe Online What Einstein once referred to as “spooky action at a distance” could be our way into a 'Star Trek' future Watching the original 'Star Trek' series as a child, the most enthralling part of any episode was the moment they dissolved during teleportation on their way down to an alien planet. The science behind that at-one-time fiction shows it is now en route to becoming fact. The possibility of teleportation was first...

Quantum Teleportation Team Breaks The Distance Record
2012-09-06 11:12:39

April Flowers for redOrbit.com - Your Universe Online An international team of researchers, including physicists from the University of Vienna and the Austrian Academy of Sciences, has achieved quantum teleportation over a record distance of 143 kilometers. The experiment marks a major step towards satellite-based quantum communication. The team transmitted quantum states between the two Canary Islands of La Palma and Tenerife over a distance of 143 kilometers, beating the previous...

Photons Teleported 60 Miles By Chinese Researchers
2012-05-13 04:46:18

A team of Chinese physicists have shattered the record for quantum teleportation, teleporting photons approximately six times further than the previous best, according to various news reports published Friday. A team of physicists hailing from the University of Science and Technology of China in Shanghai were able to teleport particles more than 97 kilometers, or over 60 miles, said Popular Science's Dan Nosowitz. That smashes the prior standard of more than 10 miles (16-plus...

Scientists from the University of Vienna's Faculty of Physics in Austria recently gave a theoretical description of teleportation phenomena in sub-atomic scale physical systems, in a publication in the European Physical Journal D. For the first time, the Austrian team proved that mathematical tools give us the freedom to choose how to separate out the constituting matter of a complex physical system by selectively analyzing its so-called quantum state. That is the state in which the system...

Quantum computers may be much easier to build than previously thought, suggests a new study in Physical Review Letters Quantum computers should be much easier to build than previously thought, because they can still work with a large number of faulty or even missing components, according to a study published today in Physical Review Letters. This surprising discovery brings scientists one step closer to designing and building real-life quantum computing systems "“ devices that could...
