Energy Dissipation in Quantum Computers

  title={Energy Dissipation in Quantum Computers},
  author={Alex T. Granik and George Frederick Chapline},
A method is described for calculating the heat generated in a quantum computer due to loss of quantum phase information. Amazingly enough, this heat generation can take place at zero temperature. and may explain why it is impossible to extract energy from vacuum fluctuations. Implications for optical computers and quantum cosmology are also briefly discussed.
