Simple source for large linear cluster photonic states

Written by admin Published in

In this project we present and analyze a resource efficient scheme for the construction of photonic linear cluster states. The scheme utilizes only one single-photon source, and the cluster states are constructed by entangling two photons at a time using only one polarizing beam splitter. We analyze the performance of the scheme for different single-photon sources and under several major imperfections, such as polarization errors, imperfect indistinguishability, beam splitters imperfections, and single-photon source imperfections, which results in the probabilistic emission of more than one photon.
This work is done in collaboration with Prof. Hagai Eisenberg.
