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...

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 communication could be an option for the absolutely secure transfer of data. The key component in quantum communication over long distances is the special phenomenon called entanglement between two atomic systems. Entanglement between two atomic systems is very fragile and up until now researchers have only been able to maintain the entanglement for a fraction of a second. But in new experiments at the Niels Bohr Institute researchers have succeeded in setting new records and...

Lasers allow scientists to observe how electrons become entangled A Princeton researcher and his international collaborators have used lasers to peek into the complex relationship between a single electron and its environment, a breakthrough that could aid the development of quantum computers. The technique reveals how an isolated electron and its surroundings develop a relationship known as a Kondo state "“ a state of matter that is of great interest to physicists and engineers. The...

New understanding of entropy From a laptop warming a knee to a supercomputer heating a room, the idea that computers generate heat is familiar to everyone. But theoretical physicists have discovered something astonishing: not only do computational processes sometimes generate no heat, under certain conditions they can even have a cooling effect. Behind this finding are fundamental considerations relating to knowledge and a lack of knowledge. The researchers publish their findings today in the...

By Roland Michel Tremblay (rm@themarginal.com) Interstellar space-travel and near-instant communication; discovering a network of intelligent extraterrestrial signals; harnessing the mysterious instantaneous quantum-entanglement effect. These are all either science fiction or things we will probably never live to see or understand, correct? Not at all. By the end of this article you will see how clarifying a simple but extremely fundamental misunderstanding in our science legacy makes all of...

New switching device could help build a dream: the ultrafast quantum Internet Northwestern University researchers have developed a new switching device that takes quantum communication to a new level. The device is a practical step toward creating a network that takes advantage of the mysterious and powerful world of quantum mechanics. The researchers can route quantum bits, or entangled particles of light, at very high speeds along a shared network of fiber-optic cable without losing the...

Atomic antennae transmit quantum information across a microchip The Austrian research group led by physicist Rainer Blatt suggests a fundamentally novel architecture for quantum computation. They have experimentally demonstrated quantum antennae, which enable the exchange of quantum information between two separate memory cells located on a computer chip. This offers new opportunities to build practical quantum computers. The researchers have published their work in the scientific journal...

Tokyo, Jan 21, 2011 - (JCN Newswire) - Professor Kohei Itoh, who is developing quantum computers based on silicon semiconductors at Keio University's Faculty of Science and Technology, together with Dr. John Morton at Oxford University and others, has successfully generated and detected quantum entanglement between electron spin and nuclear spin in phosphorus impurities added to silicon. This is the world's first successful generation and detection of entanglement, which is essential for...

Scientists have moved a step closer to creating quantum computers by generating 10 billion bits of quantum entanglement in silicon for the first time. According to a team from Britain, Japan, Canada and Germany, whose study was published in the journal Nature on Wednesday, the achievement in silicon has important implications for integration with existing technology. "Creating 10 billion entangled pairs in silicon with high fidelity is an important step forward for us," John Morton of...
