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...

Quantum Technology The Next Level Of NSA Snooping
2014-02-01 04:37:32

Enid Burns for redOrbit.com - Your Universe Online Over the past several months, news has continued to leak about the extent that the US National Security Agency (NSA) has gone to spy on the public both abroad and domestic. Much of the news has stemmed from documents revealed by NSA contractor Edward Snowden. While the Obama administration has made statements that the NSA will back off from its surveillance efforts, news has come out that the government agency is developing new tactics to...

Popular television shows such as “Doctor Who” have brought the idea of time travel into the vernacular of popular culture. But problem of time travel is even more complicated than one might think. LSU’s Mark Wilde has shown that it would theoretically be possible for time travelers to copy quantum data from the past. It all started when David Deutsch, a pioneer of quantum computing and a physicist at Oxford, came up with a simplified model of time travel to deal with the paradoxes...

A breakthrough in quantum cryptography demonstrates that information can be encrypted and then decrypted with complete security using the combined power of quantum theory and relativity - allowing the sender to dictate the unveiling of coded information without any possibility of intrusion or manipulation. Scientists sent encrypted data between pairs of sites in Geneva and Singapore, kept "perfectly secure" for fifteen milliseconds - putting into practice what cryptographers call a 'bit...

A quantum computer can solve tasks where a classical computer fails. The question how one can, nevertheless, verify the reliability of a quantum computer was recently answered in an experiment at the University of Vienna. The conclusions are published in the reputed scientific journal Nature Physics. The harnessing of quantum phenomena, such as superposition and entanglement, holds great promise for constructing future supercomputers using quantum technology. One huge advantage of such...

New 'Quantum Key Distribution' System Safeguards Secrets, Works In The Real World
2013-09-04 13:00:43

University of Calgary University of Calgary scientists have overcome an 'Achilles' heel' of quantum-based secure communication systems, using a new approach that works in the real world to safeguard secrets. The team's research – published in the journal Physical Review Letters back-to-back with similar work by a group from Hefei, China – also removes a big obstacle to realizing future applications of quantum communication, including a fully functional quantum network. "I hope...

Quantum Internet Prototype In Use At Los Alamos
2013-05-07 15:49:02

Brett Smith for redOrbit.com - Your Universe Online As concerns over cyber security grow with each newly publicized attack, computer scientists have been pursuing quantum technology as a silver bullet against would-be hackers. According to a groundbreaking announcement, scientists at Los Alamos National Labs in New Mexico have been utilizing a small-scale “quantum internet” for the past two years. Quantum cryptography is possible because of the phenomenon known as quantum...
