A loophole-free violation of Bell inequalities is of fundamental importance for demonstrating quantumnonlocality and long-distance device-independent secure communication. However, transmission lossesrepresent a fundamental limitation for photonic loophole-free Bell tests. A local precertification of thepresence of the photons immediately before the local measurements may solve this problem. We show thatlocal precertification is feasible by integrating three current technologies: (i) enhanced single-photondown-conversion to locally create a flag photon, (ii) nanowire-based superconducting single-photondetectors for a fast flag detection, and (iii) superconducting transition-edge sensors to close the detectionloophole. We carry out a precise space-time analysis of the proposed scheme, showing its viability andfeasibility. |
