@article{Chen2014ExperimentalRO, title={Experimental realization of multipartite entanglement of 60 modes of a quantum optical frequency comb.}, author={Moran Chen and Nicolas C. Menicucci and Olivier Pfister}, journal={Physical review letters}, year={2014}, volume={112 12}, pages={ 120505 } }

We report the experimental realization and characterization of one 60-mode copy and of two 30-mode copies of a dual-rail quantum-wire cluster state in the quantum optical frequency comb of a bimodally pumped optical parametric oscillator. This is the largest entangled system ever created whose subsystems are all available simultaneously. The entanglement proceeds from the coherent concatenation of a multitude of Einstein, Podolsky, and Rosen pairs by a single beam splitter, a procedure which is…
