Nonlocal realism tests and quantum state tomography in Sagnac-based type-II polarization-entanglement SPDC-source

Ali Motazedifard, Seyed Ahmad Madani, J. Jafari Dashkasan +1

We have experimentally created a robust, ultrabright and phase-stable polarization-entangled state close to maximally entangled Bell-state with $\%98$-fidelity using the type-II…
