Welcome to the Argonne National Laboratory symposium: Quantum Computing: Beginnings to Current Frontiers, which will bring together leading experts to discuss recent advances at the frontiers of quantum information and quantum computation. The past few decades have seen tremendous progress in this area, from its beginnings in the early 1980s to its present status as one of the most promising fields in science. The symposium will reflect on this progress, review contemporary successes and highlight the advances needed to make quantum computing a reality. Topics that may be discussed include:

  • Quantum algorithms
  • Quantum networks
  • Quantum simulation of physical systems
  • Quantum control and measurement
  • Quantum hardware advances


The theoretical foundation for quantum computing owes much to fundamental work by Paul Benioff in the early 1980s, which was published in three seminal papers:

[1] Paul Benioff, "The computer as a physical system: A microscopic quantum mechanical Hamiltonian model of computers as represented by Turing machines", Journal of Statistical Physics 22 (5), 563–591 (1980);

[2] Paul Benioff, "Quantum mechanical Hamiltonian models of discrete processes that erase their own histories: application to Turing machines", International Journal of Theoretical Physics 21 (3/4), 177–201 (1982);

[3] Paul Benioff, "Quantum mechanical Hamiltonian models of Turing machines", Journal of Statistical Physics 29 (3), 515–546 (1982).

In [1] Paul developed the first quantum mechanical (Hamiltonian) model for a Turing machine, and therefore of computers and the computation process. The subsequent two papers extended this framework, establishing that quantum Turing machines can be used to simulate classical computers. These three papers are regarded as the first recognizable theoretical framework for a quantum computer.

In recognition of this work Paul (together with Christopher Monroe and David Wineland) received the Quantum Communication Award in the year 2000 from the International Organization for Quantum Communication, Computing and Measurement, for "fundamental contributions to quantum computing, especially seminal work that first established quantum computation as a theoretical possibility". This symposium honors Paul's contribution to quantum computing.
