- Abstract: Rydberg atom arrays offer flexible geometries of strongly-interacting neutral
atoms, which are useful for many quantum applications such as quantum
simulation and quantum computation. Here we consider a gate-based quantum
computing scheme for a Rydberg-atom array. We utilize auxiliary atoms which are
used as a quantum wire to mediate controllable interactions among data-qubit
atoms. We construct universal quantum gates for the data atoms, by using
single-atom addressing operations. Standard one-, two-, and multi-qubit
solutions are explicitly obtained as respective sequences of pulsed operations
acting on individual data and wire atoms. A detailed resource estimate is
provided for an experimental implementation of this scheme in a Rydberg quantum
simulator.
