A sender can prepare a quantum state for remote receiver using preshared entangled pairs, only the sender's single-qubit measurement, and receiver's simple correction informed by sender. It provides resource-efficient advantages over teleportation information. Here, we propose most efficient approach to detect preparation (RSP) based on benefits powered coherence's static resources of shared pairs dynamic both RSP participants input. requires minimum one additional coherence creation operation verify RSP. Experimentally, implement introduced assessment different photon pair states generated from high-quality polarization Sagnac interferometer, confirming necessary sufficient role played demonstrating verification. Our results provide route efficiently assess in practical scenarios such as information networks.
