Quantum tomography of a bright phase-stable polarization- entangled single-mode-fiber two-photon source
Jingyun Fan, Matthew D. Eisaman, Alan L. Migdall · 2007
We have demonstrated a bright single-mode-fiber source of polarization-entangled photon pairs with visibility > 97% and fidelity > 95% at a detected coincidence rate of 7 kHz/nm over a 3 dB, 10THz bandwidth.
