Original proposal for trapped-ion quantum computation. Introduces the Cirac-Zoller gate: a CNOT between two ions mediated by the shared motional mode of the ion chain. Foundation of all trapped-ion quantum computing.

Key Results

  • Two-qubit CNOT via coupling to center-of-mass phonon mode
  • Requires individual addressing of ions with focused laser beams
  • Scalable to N ions in a linear Paul trap
  • First concrete, physically realizable proposal for universal quantum computation
