What is Information? - Part 2a - Introduction to Information Theory: Script: http://crackingthenutshell.com/what-is-information-part-2a-information-theory - Claude Shannon - Bell Labs - Father of Information Theory - A Mathematical Theory of Communication - 1948 - Book, co-written with Warren Weaver - How to transmit information efficiently, reliably & securely through a given channel (e.g. tackling evesdropping) - Applications. Lossless data compression (ZIP files). Lossy data compression (MP3, JPG). Cryptography, thermal physics, quantum computing, neurobiology - Shannon's definition not related to meaningfulness, value or other qualitative properties - theory tackles practical issues - Shannon's information, a purely quantitative measure of communication exchanges - Shannon's Entropy. John von Neumann. Shannon's information, information entropy - avoid confusion with with thermodynamical entropy - Shannon's Entropy formula. H as the negative of a certain sum involving probabilities - Examples: fair coin & two-headed coin - Information gain = uncertainty reduction in the receiver's knowledge - Shannon's entropy as missing information, lack of information - Estimating the entropy per character of the written English language - Constraints such as "I before E except after C" reduce H per symbol - Taking into account redundancy & contextuality - Redundancy, predictability, entropy per character, compressibility - What is data compression? - Extracting redundancy - Source Coding Theorem. Entropy as a lower limit for lossless data compression. - ASCII codes - Example using Huffman code. David Huffman. Variable length coding - Other compression techniques: arithmetic coding - Quality vs Quantity of information - John Tukey's bit vs Shannon's bit - Difference between storage bit & information content. Encoded data vs Shannon's information - Coming in the next video: error correction and detection, Noisy-channel coding theorem, error-correcting codes, Hamming codes, James Gates discovery, the laws of physics, How does Nature store Information, biology, DNA, cosmological & biological evolution

Antonio Acín - Quantum Information Theory Research Group

Duration: 3:15
Updated: 12 Feb 2014

ICREA Prof. at ICFO Antonio Acín leads the Quantum Information Theory research group at ICFO - Institute of Photonic Sciences. Scientists from this research group study how to exploit quantum effects to realize new information tasks without classical analog. From a pure theoretical point of view, they aim at establishing a series of laws governing the inter-conversion of the different information resources appearing in Quantum Information Theory, such as classical and quantum bits, secret bits and, especially, entanglement. They also study how to adapt all these theoretical results to what is feasible in the lab.
