NIST issues call for a new 'hash' algorithm
The National Institute of Standards and Technology (NIST) has opened a competition to develop a new cryptographic "hash" algorithm, a tool that converts a file, message or block of data to a short "fingerprint" for use in digital signatures, message authentication and other computer security applications.   view more (2007-11-09)

First quantum cryptographic data network demonstrated
A joint collaboration between Northwestern University and BBN Technologies of Cambridge, Mass., has led to the first demonstration of a truly quantum cryptographic data network.   view more (2006-08-29)

Using Carbon Nanotubes For Quantum Computing
The computing community for many years has longed to be able to to carry out high speed calculations using a genuine Quantum Computer because it would facilitate the practical factorisation of very large numbers and the searching of unordered lists and databases. The rapid breaking of secure codes based on prime numbers would have a lot of... view more... (2004-07-15)

NIST wants comments on proposed 'hash' competition
The National Institute of Standards and Technology (NIST) is planning a competition to develop one or more cryptographic "hash" algorithms to augment and revise the current Secure Hash Standard (Federal Information Processing Standard 180-2).   view more (2007-02-02)

A hidden twist in the black hole information paradox
Professor Sam Braunstein, of the University of York's Department of Computer Science, and Dr Arun Pati, of the Institute of Physics, Sainik School, Bhubaneswar, India, have established that quantum information cannot be 'hidden' in conventional ways, or in Braunstein's words, "quantum information can run but it can't hide."   view more (2007-02-28)

Researchers unite to distribute quantum keys
Researchers from across Europe have united to build the largest quantum key distribution network ever built.   view more (2009-07-02)

Scientists demonstrate all-fibre quantum logic
A team of physicists and engineers have demonstrated all-fibre quantum logic, where single photons are generated and used to perform the contolled-NOT quantum logic gate in optical fibres with high fidelity.   view more (2009-05-29)

Physicists find way to control individual bits in quantum computers
Physicists at the National Institute of Standards and Technology (NIST) have overcome a hurdle in quantum computer development, having devised* a viable way to manipulate a single "bit" in a quantum processor without disturbing the information stored in its neighbors.   view more (2009-07-08)

Quantum ghosts are helpful
The idea that far distant particles can somehow 'talk' to each other worried Einstein so much that he called it 'spooky action at a distance'.   view more (2009-04-28)

The fight for the best quantum bit (qubit)
Our results give us, for the first time, the possibility to understand the interaction between just two electrons placed next to each other in a carbon nanotube.   view more (2008-06-25)

Magnets in a spin bath
Is quantum mechanics relevant to everyday life? Latest scientific evidence suggests that it is. A paper published in Science based on research from the Paul Scherrer Institute (PSI) in Switzerland and others, reports how quantum computers behave as if they are isolated devices. The extent to which they do this can be regulated by the environment... view more... (2005-04-15)

True randomness upon request
The number of applications requiring random numbers increases continuously. They are used for example in cryptographic applications to guarantee the secrecy of electronic communications, in scientific calculations or in chance games and lotteries. In spite of this, their generation remains a difficult task. The Group of Applied Physics and the... view more... (2004-03-17)

Quantum memory and turbulence in ultra-cold atoms
Scientists at MIT have figured out a key step toward the design of quantum information networks.   view more (2009-07-20)

Experiments at UCSB push quantum mechanics to higher levels
Scientists at UC Santa Barbara have devised a new type of superconducting circuit that behaves quantum mechanically -- but has up to five levels of energy instead of the usual two. The findings are published in the August 7 issue of Science.   view more (2009-08-12)

New Law for Quantum Computers Disclosed
Arun Kumar Pati, who is currently at the University, but who is based at the Bhaba Atomic Research Centre, Mumbai, India, and Samuel L. Braunstein, at the School of Informatics have published a paper in the current issue of the International Journal, Nature [9 March 2000], describing their discovery of a new law, which they call the quantum... view more...

NIST demonstrates better memory with quantum computer bits
Physicists at the National Institute of Standards and Technology (NIST) have used charged atoms (ions) to demonstrate a quantum physics version of computer memory lasting longer than 10 seconds-more than 100,000 times longer than in previous experiments on the same ions.   view more (2005-08-11)

New Journal of Physics Quantum Cryptography Focus Issue
Real advances in quantum cryptography are described today, 12 July 2002, in a special issue of New Journal of Physics, published jointly by the Institute of Physics and the German Physical Society. Electronic transfer of information is vulnerable to attack by "eavesdroppers", hence the use of encryption techniques. Underlying nearly all forms of... view more... (2002-07-10)

Computing breakthrough could elevate security to unprecedented levels
By using pulses of light to dramatically accelerate quantum computers, University of Michigan researchers have made strides in technology that could foil national and personal security threats.   view more (2007-08-17)

Ancient neutrinos could put string theory and quantum loop gravity to the test
Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales.   view more (2005-10-14)

Physicists Entangle Photon and Atom in Atomic Cloud
uantum communication networks show great promise in becoming a highly secure communications system. By carrying information with photons or atoms, which are entangled so that the behavior of one affects the other, the network can easily detect any eavesdropper who tries to tap the system.   view more (2005-07-27)
