Physicists experimentally demonstrate one-way quantum steering
Prediction or cause? Information theory may hold the key
Quantum guessing game reveals insight into stronger-than-quantum correlations
Physicists Solve Difficult Classical Problem with One Quantum Bit
Proposed Spacetime Structure Could Provide Hints for Quantum Gravity Theory
Stronger benchmarks needed to fully quantify quantum speedup, physicist says
(Phys.org) —Texas A&M University physicist Helmut G. Katzgraber's research takes him to the crossroads of physics, computer science, quantum information theory and statistical mechanics. For more than a ...
Encryption is less secure than we thought
Information theory—the discipline that gave us digital communication and data compression—also put cryptography on a secure mathematical foundation. Since 1948, when the paper that created information theory first appear ...
Curtains down for the black hole firewall paradox: Making gravity safe for Einstein again
Research by scientists at the University of York has revealed new insights into the life and death of black holes.
Getting around the 'uncertainty principle': Physicists make first direct measurements of polarization states of light
Researchers at the University of Rochester and the University of Ottawa have applied a recently developed technique to directly measure for the first time the polarization states of light. Their work both ...
Never mind the noise: Quantum entanglement allows channel information rate to exceed Shannon zero-error capacity
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 ...
Quantum measurements: Common sense is not enough
(PhysOrg.com) -- In comparison to classical physics, quantum physics predicts that the properties of a quantum mechanical system depend on the measurement context, i.e. whether or not other system measurements ...
Researcher identifies just 8 patterns as the cause of all humor
Evolutionary theorist Alastair Clarke has today published details of eight patterns he claims to be the basis of all the humour that has ever been imagined or expressed, regardless of civilization, culture or personal taste.
New theory could yield more-reliable communication protocols
Communication protocols for digital devices are very efficient but also very brittle: They require information to be specified in a precise order with a precise number of bits. If sender and receiver—say, ...
