Asher Peres (born 1934 and died January 1, 2005) was an Israeli physicist, considered a pioneer in quantum information theory. According to his autobiography, he was born in Beaulieu-sur-Dordogne in France, where his father, a Polish electrical engineer, had found work laying down power lines. Peres was given the name Aristide at birth, since the name his parents wanted to choose, Asher, the name of his maternal grandfather, was not on a list of permissible names. When Peres went to live in Israel, he changed his first name to Asher and his family name from Pressman to Peres. 1934 was a common year starting on Monday (link will take you to calendar). ... January 1 is the first day of the calendar year in both the Julian and Gregorian calendars. ... 2005 is a common year starting on Saturday of the Gregorian calendar and is the current year. ... A physicist is a scientist trained in physics. ... In quantum mechanics, quantum information is physical information that is held in the state of a quantum system. ...

Peres obtained his Ph. D in 1959 at Technion -Israel Institute of Technology under Nathan Rosen. Peres spent most of his academic career at Technion, where in 1988 he was appointed distinguished professor of physics. A doctorate is an academic degree of the highest level. ... 1959 was a common year starting on Thursday of the Gregorian calendar. ... The Technion - Israel Institute of Technology (הטכניון - מכון טכנולוגי לישראל) is a university in Haifa, Israel. ... Nathan Rosen (March 22, 1909 – December 18, 1995) was a physicist. ...

Peres is well-known for his work relating quantum mechanics and information theory, an approach which is extensively used in his textbook referenced below. Among other things, he helped to develop the Peres-Horodecki criterion for entanglement as well as the concept of quantum teleportation. Fig. ... Information theory is the mathematical theory of data communication and storage founded in 1948 by Claude E. Shannon. ... The Peres-Horodecki criterion is a necessary condition, for the joint density matrix of two systems and , to be separable. ... Quantum teleportation is a technique discussed in quantum information science to transfer a quantum state to an arbitrarily distant location using an entangled state and the transmission of some classical information. ...
