Quantum-capacity bounds in spin-network communication channels
Stefano Chessa, Marco Fanizza, Vittorio Giovannetti
Using the Lieb-Robinson inequality and the continuity property of the quantum capacities in terms of the diamond norm, we derive an upper bound on the values that these capacities…

Time-Polynomial Lieb-Robinson bounds for finite-range spin-network models
Stefano Chessa, Vittorio Giovannetti
The Lieb-Robinson bound sets a theoretical upper limit on the speed at which information can propagate in non-relativistic quantum spin networks. In its original version, it result…
