Phys. Rev. Lett. 104, 100502 (2010) [4 pages]Experimental Demonstration of Photonic Entanglement Collapse and RevivalReceived 3 September 2009; revised 13 February 2010; published 9 March 2010 We demonstrate the collapse and revival features of the entanglement dynamics of different polarization-entangled photon states in a non-Markovian environment. Using an all-optical experimental setup, we show that entanglement can be revived even after it suffers from sudden death. A maximally revived state is shown to violate a Bell’s inequality with 4.1 standard deviations which verifies its quantum nature. The revival phenomenon observed in this experiment provides an intriguing perspective on entanglement dynamics. © 2010 The American Physical Society URL:
