Cluster-state preparation and multipartite entanglement analyzer with fermions
Xinglai Zhang, Mang Feng, K. Gao · Physical Review A · 2006
Quantum cluster states and entangled-state analyzers are essential to measurement-based quantum computing. We propose to generate a quantum cluster state and to make a multipartite entanglement analyzer by using noninteracting free electrons or conduction electrons in quantum dots, based on polarizing beam splitters, charge detectors, and single-spin rotations. Our schemes are deterministic without the need of qubit-qubit interaction.
