Limits on the storage of quantum information in a volume of space
Steven T. Flammia, Jeongwan Haah, Michael J. Kastoryano +1
We study the fundamental limits on the reliable storage of quantum information in lattices of qubits by deriving tradeoff bounds for approximate quantum error correcting codes. We…
Finite correlation length implies efficient preparation of quantum thermal states
Fernando G. S. L. Brandao, Michael J. Kastoryano
Preparing quantum thermal states on a quantum computer is in general a difficult task. We provide a procedure to prepare a thermal state on a quantum computer with a logarithmic de…
Emergence of spontaneous symmetry breaking in dissipative lattice systems
H. Wilming, M. J. Kastoryano, A. H. Werner +1
A cornerstone of the theory of phase transitions is the observation that many-body systems exhibiting a spontaneous symmetry breaking in the thermodynamic limit generally show exte…
