Benchmarking Quantum Correlations in Scalable Photonic Systems
Jan Sperling, Johannes Tiedau, Melanie Engelkemeier, Benjamin Brecht, Christine Silberhorn · Conference on Lasers and Electro-Optics · 2021
A benchmark protocol is established to certify quantum correlations, demanding an exponential increase of resources. We handle this scaling and show nonclassicality of up to ten photons distributed over more than sixty modes.
