Scope of HOTPI-2013:

Physical informatics is the field where the laws of physics are utilized to make new schemes for logic, computing, and communication systems or to analyze the fundamental limits of their performance. In-spite of years of development (and much hype in the media), there remains a great deal of controversy surrounding many of the developments, and this has clouded the interpretation of the relevant physics in numerous discussions.

During the regular sessions invited and regular speakers will present their papers. Out of these sessions, several debate sessions will also be arranged, see below. At these discussions, a "Pro" and a "Con" team will present their points
and then publicly debate the other panel's arguments with the active participation of a Moderator and that of the Audience, while these sessions will be recorded and published.

The following public discussions are planned:

i) Debate session about the security of quantum key distribution.

  Questions to be debated:

  Moderator: Giacomo Mauro D'Ariano (Univ. Pavia)

  Pro Team: Eleni Diamanti (CNRS - TÚlÚcom ParisTech) and Renato Renner (ETH)

  Con Team:
Vadim Makarov (Univ. Waterloo) and Horace Yuen (Northwestern Univ.)                   

ii) Debate session about the possibility of reversible computing and the validity of Landauer's principle (including Maxwell demons and Szilard engines).

  Questions to be debated:

  Moderator: Dave Ferry/Alexander Kirk (ASU)

  Pro Team: Neal Anderson (Univ. Massach. Amherst), Renato Renner (ETH)

  Pro-only-irreversible-but-dissipative-Brownian computers: Ferdinand Peper  (NICT, Kobe); Rest: Con

  Con Team:
Robert Alicki, Laszlo B. Kish (TAMU), Wolfgang Porod (Univ. Notre Dame)

iii) Debate session about the future of quantum computing.

  Questions to be debated:

  Moderator: Wolfgang Porod (Univ. Notre Dame)

  Pro Team: Derek Abbott  (Univ. Adelaide),  Phil Hemmer (TAMU), Dave Ferry/Alexander Kirk (ASU) - partial-Pro

  Con Team
FTM 2012 article updated Michel Dyakonov (Univ. Montpellier), Laszlo Kish (TAMU)


Papers will be published as open-access publications in  International Journal of Modern Physics: Conference Series  after the meeting. Note change of deadline at the bottom of this page. (Also note other change: due to participants' requests, no pre-conference virtual proceedings will be published.)
