| الوصف: | Photon-mediated quantum networks generally consist of quantum channels, repeaters, and end nodes. Remote state preparation (RSP) enables one of the end nodes to prepare the states of the other end nodes remotely. RSP also serves as a deterministic single-photon source for networking communications. Herein, we theoretically and experimentally investigate how networking RSP surpasses any classical emulation without entanglement and qubit unitaries. We introduce a new type of quantum resource, which we refer to as RSP capability, to validate all the static and dynamic elements required for nonclassical state preparation and transmission, such as quantum channels and repeaters. This goes beyond the static resources of quantum correlations. We experimentally demonstrate the RSP capability measurement of the photon pairs created by a polarization Sagnac interferometer, including the transition between classical and nonclassical RSP depending on the photon-pair qualities. Our results help reveal the quantum advantages arising when networking RSP plays a role. Comment: arXiv admin note: substantial text overlap with arXiv:2008.06238 |
