David DiVincenzo

from Wikipedia, the free encyclopedia

David P. DiVincenzo (* 1959 in Philadelphia ) is an American physicist who studies quantum computers and is one of the pioneers in this field.

Live and act

DiVincenzo received his PhD in electrical engineering from the University of Pennsylvania in 1983 . He was a post-graduate student at Cornell University . From 1985 he was at the Thomas J. Watson Research Center at IBM , where he became research manager. In 2010 he received an Alexander von Humboldt Professorship and in 2011 became Professor at the Institute for Theoretical Quantum Information at RWTH Aachen University and Director of the Peter Grünberg Institute for Theoretical Nanoelectronics at Forschungszentrum Jülich .

In 1997 DiVincenzo and Daniel Loss ( Basel ) proposed a quantum computer with the spin of electrons in quantum dots as qubits ( Loss-DiVincenzo quantum computer ). Work on its experimental realization comes from, among others, Leo Kouwenhoven .

In 1996 he published five criteria for a quantum computer:

  • A scalable physical system with well-defined qubits
  • The possibility of initializing the qubits to a given state
  • A universal set of quantum gates
  • long relevant decoherence times, much longer than the operating time of the gates
  • A device specific to the qubits to measure their condition

He also stated two additional criteria for quantum communication:

  • The possibility of converting stationary qubits and qubits in the communication channel into one another
  • The ability to transmit qubits over long distances via a communication channel

DiVincenzo is a Fellow of the American Physical Society and Associate Editor of the Reviews of Modern Physics and editor of The virtual journal of quantum computation .
