A research team led by University of Toronto Professor Hoi-Kwong Lo has found a new quantum encryption method to foil even the most sophisticated hackers. The discovery is outlined in the latest issue of Physical Review Letters. Quantum cryptography is, in principle, a foolproof way to prevent hacking. It ensures that any attempt by an eavesdropper to read encoded communication data will lead to disturbances that can be detected by the legitimate users. Therefore, quantum cryptography...

Researchers have discovered a new way in which computers based on quantum physics could beat the performance of classical computers. The work, by researchers based in Singapore and the UK, implies that a Matrix-like simulation of reality would require less memory on a quantum computer than on a classical computer. It also hints at a way to investigate whether a deeper theory lies beneath quantum theory. The finding emerges from fundamental consideration of how much information is needed to...

Quantum cryptography is the ultimate secret message service. Now new research, to be presented at the 2012 AAAS Annual Meeting, shows it can counter even the ultimate paranoid scenario: when the equipment or even the operator is in the control of a malicious power. Until now, quantum cryptography protocols have always assumed that an adversary would not have access to information about any choices that are made during the process of encryption. "We are challenging this assumption," says...

A report published this week indicates that a new, secure, high-speed computing technology based on quantum physics is compatible with “cloud computing” and could eventually revolutionize the world of computers as we currently understand it. Blind quantum computing, as it´s being called, exploits uncertainties in quantum physics to carry out ultra-fast computations. And according to an international team of researchers who published their work in this week´s issue of...

Scientists and engineers have proven the worth of quantum cryptography in telecommunication networks by demonstrating its long-term effectiveness in a real-time network. Their international network, created in collaboration with ID Quantique and installed in the Geneva metropolitan area and crossing over to the site of CERN in France, ran for more than one-and-a-half years from the end of March 2009 to the beginning of January 2011. Published today, 2 December, in the Institute of...

Thanks to advances in experimental design, physicists at the National Institute of Standards and Technology (NIST) have achieved a record-low probability of error in quantum information processing with a single quantum bit (qubit)–the first published error rate small enough to meet theoretical requirements for building viable quantum computers. A quantum computer could potentially solve certain problems that are intractable using today's technology, even supercomputers. The NIST...
