Abstract

This article focuses on the experimental demonstration of a four-branch continuous variable (CV) quantum teleportation network with a star topology, where a central station mediates communication among multiple nodes using entangled sideband modes derived from a single squeezed light source. The network employs an innovative frequency-comb-type auxiliary control beam generated by waveguide amplitude modulators to manage entangled modes efficiently, enabling deterministic CV quantum teleportation with fidelities above 0.830 at each node, surpassing the no-cloning limit of 2/3. This work highlights the potential scalability of star-topology CV quantum networks and their role in advancing quantum communication protocols by combining multiplexed entanglement distribution with robust control techniques.
