Modular architectures to deterministically generate graph states

Graph states are a family of stabilizer which can be tailored towards various applications in photonic quantum computing and communication. In this paper, we present modular design based on dot emitters coupled to waveguide optical fiber delay lines deterministically generate N-dimensional cluster other useful graph such as tree repeater states. Unlike previous proposals, our requires no two-qubit gates dots at most one switch, thereby, minimizing challenges usually posed by these requirements. Furthermore, discuss the error model for demonstrate fault-tolerant memory with an threshold 0.53% case 3d state Raussendorf-Harrington-Goyal (RHG) lattice. We also provide fundamental upper bound correctable loss RHG percolation theory, is 1.24 dB or 0.24 depending whether directly generated obtained from simple cubic state, respectively.
