Gilles Brassard

From Wikipedia, the free encyclopedia

Gilles Brassard was born in Montréal, Canada, in 1955. He received a Masters degree from the Université de Montréal in 1975, and obtained his Ph.D. in Computer Science from Cornell University in 1979, working in the field of cryptography with John Hopcroft as his advisor. He has been a faculty member of the Université de Montréal ever since, where he became Full Professor in 1988.

Brassard is best known for his fundamental work in quantum cryptography, quantum teleportation, quantum entanglement distillation, pseudo-telepathy, and the classical simulation of quantum entanglement. Some of these concepts are still theoretical, but others have been implemented in the laboratory.

In 1984, together with Charles H. Bennett, he invented the BB84 protocol for quantum cryptography. He later extended this work to include the Cascade error correction protocol, which performs efficient detection and correction of noise caused by eavesdropping on quantum cryptographic signals.
