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)

Tiny avalanche photodiodes target bioterrorism agents
After the anthrax attacks in the United States in 2001 the threat of a larger and more deadly bioterrorism attack - perhaps from smallpox, plague or tularemia - became very real. But the ability to detect such biological agents and rapidly contain an attack is still being developed. view more (2005-09-14)

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)
Scientists discover new method of observing interactions in nanoscale systems
Scientists have used new optical technologies to observe interactions in nanoscale systems that Heisenberg's uncertainty principle usually would prohibit, according to a study published Jan. 17 in the journal Nature. view more (2008-01-17)
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)
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)
Hebrew University Scientist One Of Four Profiled In Nature In Connection With Einstein Centenary
Dr. Dorit Aharonov, of the Benin School of Engineering and Computer Science at the Hebrew University of Jerusalem, has been chosen by the science journal Nature as one of four young theorists being profiled in the current issue of the magazine to mark the 100th anniversary of Albert Einstein's publication of three of his landmark theories in 1905,... view more...
