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)
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)
Quantum dots reviewed — Could these nanoparticles hold the cure to cancer?
The worlds of medical and biological research are abuzz with the promises offered by nanoparticles known as semiconductor quantum dots. These Quantum Dots (QDs) have unique optical and electronic properties that make them suitable for breakthrough treatments such as the detection and destruction of cancer cells. view more (2006-09-15)
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)
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)
The next step in quantum computing
A team of physicists in the United States has made an important step towards making quantum computing a reality. Research into a new type of noiseless quantum information bit, or qubit, is published today in the joint Institute of Physics and German Physical Society journal, New Journal of Physics. view more (2002-02-12)
Imaging quantum entanglement
An international team including scientists from the London Centre for Nanotechnology (LCN) today publishes findings in the journal 'Proceedings of the National Academy of Sciences' (PNAS) demonstrating the dramatic effects of quantum mechanics in a simple magnet. view more (2007-09-24)
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...

Quantum computer solves problem, without running
By combining quantum computation and quantum interrogation, scientists at the University of Illinois at Urbana-Champaign have found an exotic way of determining an answer to an algorithm - without ever running the algorithm. view more (2006-02-23)
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 at UC Santa Barbara make discovery in quantum mechanics
Physicists at UC Santa Barbara have made an important advance in quantum mechanics using a superconducting electrical circuit. The finding is reported in this week's issue of the journal Nature. view more (2009-09-24)
UCSB physicists move 1 step closer to quantum computing
Physicists at UC Santa Barbara have made an important advance in electrically controlling quantum states of electrons, a step that could help in the development of quantum computing. view more (2009-11-20)

Classical Physics falls short
With the aid of so-called quantum dots, PhD student Wilfred van der Wiel has gained new insight into quantum-mechanical processes. "This is one of the paths that could lead to smaller, but also fundamentally different electronics, " says Van der Wiel. He will receive his degree on 28 January for his fundamental research. Parts of his... view more... (2002-01-20)
