A new kind of CNOT-gate implementation for information processing with trapped ions

  • K. Pahlke

A sequence of laser pulses is presented to implement a new kind of CNOT-gate in an linear arrangement of trapped ions. This type of quantum gate enables the designer of quantum algorithms to “send information into the phonon bus” controlled by the information stored in one of the ions. Some simulation results are given to show the dynamics of the system during the gate implementation. The simulation gives information about the leakage and the gate accuracy.
