Query: Entangling quantum gate in trapped ions via Rydberg blockade   We present a theoretical analysis of the implementation of an entangling
quantum gate between two trapped Ca$^+$ ions which is based on the dipolar
interaction among ionic Rydberg states. In trapped ions the Rydberg excitation
dynamics is usually strongly affected by mechanical forces due to the strong
couplings between electronic and vibrational degrees of freedom in
inhomogeneous electric fields. We demonstrate that this harmful effect can be
overcome by using dressed states that emerge from the microwave coupling of
nearby Rydberg states. At the same time these dressed states exhibit long range
dipolar interactions which we use to implement a controlled adiabatic phase
gate. Our study highlights a route towards a trapped ion quantum processor in
which quantum gates are realized independently of the vibrational modes.
