Research Summary
Our final goal is the realization of fault-tolerant large-scale universal optical quantum computers with our original deterministic quantum teleportation methodology. The heart of this methodology is cluster states of optical modes, which are special multipartite entangled states and correspond to “quantum look-up tables for quantum computation”. We will pursue the size and precision of the cluster states with our original time-domain multiplexing methodology.
