Entangling many photons that never co-existed

The demonstration of multi-particle entangled states, where entanglement is generated between more than two particles, is crucial for the advancement of quantum information science. I will present our approach in which we generate multi-photon entangled states using only one source of entangled pairs. Even though all the photons do not coexist at any moment in time, we still observe quantum characteristics of multi-photon entanglement i.e., one detected photon exhibits quantum correlations with another photon that will be created only at a later time. Consequently, entangled photon states of larger numbers than before are practically realizable.
