Quantum Cayley networks of the hypercube
Christopher Facer, Jason Twamley, James D. Cresser · Physical Review A · 2008
We develop the work of Christandl et al. [Phys. Rev. A 71, 032312 (2005)], to show how a $d$-hypercube homogenous network can be dressed by additional links to perfectly route quantum information between any given input and output nodes in a duration that is independent of the routing chosen and, surprisingly, the size of the network.
