Looking Beyond Space And Time To Cope With Quantum Theory
2012-10-29 09:30:54

Centre for Quantum Technologies at the National University of Singapore Physicists have proposed an experiment that could force us to make a choice between extremes to describe the behavior of the Universe. The proposal comes from an international team of researchers from Switzerland, Belgium, Spain and Singapore, and is published today in Nature Physics. It is based on what the researchers call a 'hidden influence inequality'. This exposes how quantum predictions challenge our best...

New Perception Of The Remote Control Of Quantum Systems
2012-08-06 09:50:41

A fundamental characteristic of quantum physics is the fact that two or more particles can exhibit correlations stronger than classically allowed. This unique characteristic applies particularly to quantum entanglement: as soon as the quantum state of a particle is measured the state of its entangled partner changes accordingly, regardless of how far apart the two entangled particles might be. This feature allows for the remote quantum state preparation, which is an essential ingredient for...

Study describes greater chances of accessing more reliable information on applications in quantum computing and cryptography Theoretical physicist Filippo Miatto and colleagues from the University of Strathclyde, Glasgow, UK, have found a new method of reliably assessing the information contained in photon pairs used for applications in cryptography and quantum computing. The findings, published in EPJ D´, are so robust that they enable access to the information even when the...

Efficient, Tunable Interface For Quantum Networks
2012-05-23 12:59:16

Quantum technologies promise to redefine the landscape of information processing and communication. We already live in an information age, in which vast amounts of data are sent around the world over optical fibers, but future quantum networks may be many times more powerful. These networks will require interfaces that can transfer information from quantum processors onto light particles (photons). Such interfaces will allow optical fibers to transmit information-bearing photons between...

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...

New device, developed by team of engineers led by Professor Amr Helmy (ECE), could bring quantum computing to your home or office In the age of high-speed computing, the photon is king. However, producing the finely tuned particles of light is a complex and time-consuming process, until now. Thanks to the work by a team of engineers led by Professor Amr Helmy of The Edward S. Rogers Sr. Department of Electrical & Computer Engineering, a novel solution has been identified that will...

Quantum Physics Mimics Spooky Action Into The Past
2012-04-23 09:37:30

Physicists of the group of Prof. Anton Zeilinger at the Institute for Quantum Optics and Quantum Information (IQOQI), the University of Vienna, and the Vienna Center for Quantum Science and Technology (VCQ) have, for the first time, demonstrated in an experiment that the decision whether two particles were in an entangled or in a separable quantum state can be made even after these particles have been measured and may no longer exist. Their results will be published this week in the journal...

Researchers at the UNIGE have succeeded in entangling 2 macroscopic crystals, a step towards the development of quantum memory For almost fifteen years Professor Nicolas Gisin and his physicist col- laborators have been entangling photons. If this exercise seems to them perhaps henceforth trivial, it continues to elude us ordinary humans. The laws that govern the quantum world are so strange that they completely escape us human beings confronted with the laws of the macroscopic world. This...

Physicists have developed the first conclusive test to better understand high-energy particles correlations. Researchers have devised a proposal for the first conclusive experimental test of a phenomenon known as ℠Bell´s nonlocality.´ This test is designed to reveal correlations that are stronger than any classical correlations, and do so between high-energy particles that do not consist of ordinary matter and light. These results are relevant to the so-called ℠CP...

The fundamental resource that drives a quantum computer is entanglement–the connection between two distant particles which Einstein famously called 'spooky action at a distance'. The Bristol researchers have, for the first time, shown that this remarkable phenomenon can be generated, manipulated and measured entirely on a tiny silica chip. They have also used the same chip to measure mixture–an often unwanted effect from the environment, but a phenomenon which can now be...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
