Entanglement percolation in quantum networks
Abstract:- Reliable information transmission between two sites of a network
naturally leads to a percolation problem. When the information to be
transmitted is quantum an exciting possibility arises: transform the
network performing well chosen measurements to enhance the transmission
probability. This idea, introduced recently by Acin, Cirac and
Lewenstein is now systematically and successfully applied to a variety
of two-dimensional networks, but open questions show that a complete
theory is missing. The talk will involve some quanta, some network
geometry, some percolation and, hopefully, some fun. No knowledge of
quantum theory or percolation theory is assumed. Graduate students are
encouraged to attend. [video]
