One-Step Scheme for Realizing N -Qubit Quantum Phase Gates with Hot Trapped Ions
Shi-Biao Zheng, LU Dao-ming · Communications in Theoretical Physics · 2011
A scheme is presented for realizing an N-qubit quantum phase gate with trapped ions. Taking advantage of the virtual excitation of the vibrational mode, the qubit system undergoes a full-cycle of Rabi oscillation in the selective symmetric Dicke subspace. The scheme only involves a single step and the operation is insensitive to thermal motion. Moreover, the scheme does not require individual addressing of the ions.
