  • Abstract
    Realisation of controlled-NOT gate (CNOT) operation between two individual ions as a universal two-bit quantum gate based from the proposals of Cirac and Zoller, is presented. Two single 40Ca+ ions are held in a linear Paul trap and are individually addressed with focused laser beams. Superpositions of the S12 /and the D52/ long lived electronic states represent a qubit. A sequence of well suited laser pulses flips the state of the target ion conditional to the state of the control ion.
