Scaling Quadripartite Entanglement in the Optical Frequency Comb - Matthew Pysher

Scalability and coherence are two essential requirements for the experimental implementation of quantum information and quantum computing. In this talk, I will address the former and report the simultaneous generation of 15 quadripartite continuous-variable cluster states over 60 cavity modes in the optical frequency comb of a single optical parametric oscillator. This result paves the way for the realization of large-scale entangled states for quantum computing, as a slightly more sophisticated version of this experimental method has theoretically shown the ability to produce arbitrarily large square-grid cluster states suitable for universal one-way quantum computing.
