Gapless Hamiltonians for the toric code using the PEPS formalism
Carlos Fernández-González, Norbert Schuch, Michael M. Wolf +2
We study Hamiltonians which have Kitaev's toric code as a ground state, and show how to construct a Hamiltonian which shares the ground space of the toric code, but which has gaple…
Are problems in Quantum Information Theory (un)decidable?
Michael M. Wolf, Toby S. Cubitt, David Perez-Garcia
This note is intended to foster a discussion about the extent to which typical problems arising in quantum information theory are algorithmically decidable (in principle rather tha…
A Cutoff Phenomenon for Quantum Markov Chains
Michael J. Kastoryano, David Reeb, Michael M. Wolf
We derive upper and lower bounds on the convergence behavior of certain classes of one-parameter quantum dynamical semigroups. The classes we consider consist of tensor product cha…
Quantum Tomography under Prior Information
Teiko Heinosaari, Luca Mazzarella, Michael M. Wolf
We provide a detailed analysis of the question: how many measurement settings or outcomes are needed in order to identify a quantum system which is constrained by prior information…
