What number is halfway between 1 and 9? Is it 5—or 3?
A new information-theoretical model of human sensory perception and memory sheds light on some peculiarities of the nervous system.
Physicists experimentally demonstrate one-way quantum steering
Information theory helps unravel DNA's genetic code
'Superinformation,' or the randomness of randomness, can be used to predict the coding and noncoding regions of DNA.
A roll of the dice: Quantum mechanics researchers show that nature is unpredictable
Many of the predictions we make in everyday life are vague, and we often get them wrong because we have incomplete information, such as when we predict the weather.
Game of go: A complex network
Could computers ever beat the best go players? Although unthinkable at this stage, this could soon become possible, thanks to CNRS theorists. For the first time, two scientists from the Theoretical Physics ...
How quantum physics could make 'The Matrix' more efficient
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 ...
Quantum copies do new tricks
One of the strange features of quantum information is that, unlike almost every other type of information, it cannot be perfectly copied. For example, it is impossible to take a single photon and make a number of photons ...
New error-correcting codes guarantee the fastest possible rate of data transmission
Error-correcting codes are one of the triumphs of the digital age. Theyre a way of encoding information so that it can be transmitted across a communication channel such as an optical fiber o ...
U of Toronto experiment named top breakthrough of 2011 by Physics World
Aephraim Steinberg and colleagues at the Centre for Quantum Information and Quantum Control at the University of Toronto had the top physics breakthrough of the year according to Physics World magazine.
Prediction or cause? Information theory may hold the key
Quantum teleportation analysed by mathematical separation tool
Scientists from the University of Vienna's Faculty of Physics in Austria recently gave a theoretical description of teleportation phenomena in sub-atomic scale physical systems, in a publication in the European Physical Jo ...
The economics of database searching
(PhysOrg.com) -- Searching the internet might seem simple, but applying a little bit of economic theory to information retrieval can shed some light on the best search strategies to adopt, according to researchers.
Escaping gravity's clutches: The black hole breakout
New research by scientists at the University of York gives a fresh perspective on the physics of black holes.
Quantum knowledge cools computers: New understanding of entropy
From a laptop warming a knee to a supercomputer heating a room, the idea that computers generate heat is familiar to everyone. But theoretical physicists have discovered something astonishing: not only do computational processes ...
