Topological Quantum Computing - Quantum Optics Group at ETH
... Calculating the time evolution of an interacting quantum many-body system is an NP-hard problem (Kitaev et al., 2002). Turning this around, one could say: this physical system efficiently solves an NP-hard problem — its own evolution. If we could encode other problems onto such a quantum system, we ...
