3-D images, with only one photon per pixel
November 28, 2013New scheme could enable laser rangefinders to infer depth from a hundredth as much light — and to produce images from only one nine-hundredth the light.
Encryption is less secure than we thought
August 13, 2013For 65 years, most information-theoretic analyses of cryptographic systems have made a mathematical assumption that turns out to be wrong.
Beefing up public-key encryption
February 15, 2013MIT researchers show how to secure widely used encryption schemes against attackers who have intercepted examples of successful decryption.
Explaining the origins of word order using information theory
October 9, 2012Researchers believe that information theory — the discipline that gave us digital communication — can explain differences between human languages.
What number is halfway between 1 and 9? Is it 5 — or 3?
October 4, 2012A new information-theoretical model of human sensory perception and memory sheds light on some peculiarities of the nervous system.
The elusive capacity of networks
May 14, 2012Calculating the total capacity of a data network is a notoriously difficult problem, but information theorists are beginning to make some headway.
Perfect communication with imperfect chips
August 3, 2011Error-correcting codes discovered at MIT can still guarantee reliable communication, even in cellphones with failure-prone low-power chips.
How wise are crowds?
November 16, 2010By melding economics and engineering, researchers show that as social networks get larger, they usually get better at sorting fact from fiction.
Can you find me now?
September 8, 2010By demonstrating fundamental limits on their accuracy, MIT researchers show how to improve wireless location-detection systems.
Jack Wozencraft, information theorist at MIT, 1925-2009
January 21, 2010Jack Wozencraft, considered one of the pioneers of coding theory in the nascent field of information theory, died peacefully August 31, 2009.
