Asher Peres (January 30, 1934January 1, 2005) was an Israeli physicist, considered a pioneer in quantum information theory.

In 2003 Asher Peres proposed one answer to Einsteins-Podolsky-Rosen puzzle of quantum entanglement otherwise deemed "Spooky action at a distance" (Glick 365). Asher Peres thought that information is physical and Einsteins puzzle came too early. He thought that Claude E. Shannon's information theory could answer the problem (Glick 366). He stated "Information is not just an abstract notion. It requires a physical carrier, and the latter is (approximately) localized. After all, it was the business of the Bell Telephone Company to transport information from one telephone to another telephone, in a different location...When Alice measures her spin, the information she gets is localized at her position, and will remain so until she decides to broadcast it. Absolutely nothing happens at Bob's location...It is only when Alice informs Bob of the result she got (by mail, telephone, radio, or by means other than material carrier, which is naturally restricted to the speed of light) that Bob realizes that his particle has definite pure state (Glick 367). This attempted to embody the transactions made from quantum entanglement. Peres thought that much of the quantum theory was too abstract and distanced itself from

  • Some authors state that the last stage in this chain of measurements involves "consciousness," or the "intellectual inner life" of the observer, by virtue of the "principle of psycho-physical parallelism." Other authors introduce a wave function for the entire universe. In this book, I shall refrain from using concepts that I do not understand.
