Efficient fusion of photonic W-states with nonunitary partial-swap gates
We introduce a nonunitary partial-swap gate for fusing arbitrary small-sized photonic W -states into a large-scale entangled network of W -state efficiently without ancillary photons. A partial-swap gate is designed in an optical architecture based on linear optics elements. By introducing auxiliary...
