The authors present an optimal cavity design for atom-photon entangling gates based on cavity quantum electrodynamics, considering finite photon-pulse duration. By minimizing both the photon loss probability and the error rate due to temporal mode mismatch, they suggest that a cavity has an optimal length for the atom-photon gate, providing a guideline for implementing quantum information processing.
