Abstract: | We propose a scheme for implementing two-qubit geometric phase gate via the
adiabatic evolution for trapped ions in thermal motion, leveraging on the
stimulated Raman adiabatic passage with the geometric phase mechanism.
Evolution along a dark state makes our scheme not only immune from decoherence
due to spontaneous emission from excited states, but also rid off the
dynamical phase. Furthermore, due to the opposite detuning of the driving
lasers, the vibrational states of the trapped ions are only virtually excited
during the operations, so our scheme is also insensitive to the occupation
number of the vibrational mode. |
