 "Prospects for Quantum Computation" 
  
 David DiVincenzo 
 IBM Research 
  
 Abstract: 
 A "standard model" for the physical implementation of a quantum 
 computer was laid out some years ago.  It indicated a set of 
 capabilities that had to be achieved to make quantum processing 
 possible: 1) systems with well-characterized qubits must be 
 constructed. 2) These qubits should be initializable to the "0" state. 
 3) It must be possible to control the one- and two-qubit Hamiltonian of 
 the system, so that unitary quantum logic gates are enacted. 4) 
 Decoherence and imprecision of gate operations must be kept very low. 
 5) Reliable measurements of the quantum state of individual qubits must 
 be possible.  In this talk I will indicate current progress towards 
 these goals. 
  
  
 Bio: 
  
 Dr. David P. DiVincenzo received his Ph.D. (1983), M.S.E. (1980) and 
 B.S.E. (1979) from the University of Pennsylvania. Since 1985, he has 
 been a Research Staff Member in the Physical Sciences Department at the 
 IBM T. J. Watson Research Center in Yorktown Heights, NY. He has worked 
 throughout his career in various problems in condensed matter physics. 
 Since 1993, one of his main interests has been quantum computing; he 
 has important results in quantum information theory, and in the 
 physical realizations of quantum computers. In particular, he is well 
 known for proposing a set of five criteria (commonly called 
 DiVincenzo's checklist) for the physical implementation of quantum 
 computers. He is a Fellow of the American Physical Society and the 
 Editor-in-Chief of the Virtual Journal of Quantum Information.
