Phys. Rev. A 70, 012305 (2004) [8 pages]Multiqubit controlled unitary gate by adiabatic passage with an optical cavityReceived 31 October 2003; revised 3 February 2004; published 9 July 2004 A new implementation of quantum gates by adiabatic passage with an optical cavity is proposed. This implementation allows one to perform not only elementary gates, such as one-qubit gates and a controlled-NOT gate, but also multiqubit controlled unitary gates. Some quantum gates are numerically simulated. From the simulation results, it is concluded that this implementation of the three-qubit controlled gates is more efficient than decomposing into the elementary gates. © 2004 The American Physical Society URL:
