Multipartite Entanglement in a Discrete Magnetic Bands Magnetic Lattice

Using magneto-optical materials, an asymmetric multi-quantum state magnetic lattice is proposed to host an entangled multipartite system formed by using a quantum degenerate gas of ultracold atoms in a Bose Einstein Condensate (BEC). The discrete magnetic bands magnetic lattice is devised to locate a controllable long-range entanglement of a many harmonic oscillator system well separated in space. The confinement of the coupled magnetic quantum well (CMQW) system may significantly improve the condition for the long-range entanglement of the multipartite (multi-qubits) to be used in quantum information processors.
