Creation of a polarization W state using optical fibre multiports
Bao‐Sen Shi, Akihisa Tomita · Journal of Modern Optics · 2005
A scheme for experimental creation of a polarization W state is reported in this paper. This scheme is based on a common commercial multiport fibre coupler and single photon source and it is feasible using current technology. This scheme has a higher efficiency and can be easily extended to generate a multiphoton W state with a photon number larger than 4.
