Preparing topological PEPS on a quantum computer
Martin Schwarz, Toby S. Cubitt, Kristan Temme +2
Simulating of exotic phases of matter that are not amenable to classical techniques is one of the most important potential applications of quantum information processing. We presen…
Entanglement, fractional magnetization and long-range interactions
Andrea Cadarso, Mikel Sanz, Michael M. Wolf +2
Based on the theory of Matrix Product States, we give precise statements and complete analytical proofs of the following claim: a large fractionalization in the magnetization or th…
Existence of an information unit as a postulate of quantum theory
Lluis Masanes, Markus P. Mueller, Remigiusz Augusiak +1
Does information play a significant role in the foundations of physics? Information is the abstraction that allows us to refer to the states of systems when we choose to ignore the…
Matrix Product States with long-range Localizable Entanglement
Thorsten B. Wahl, David Perez-Garcia, J. Ignacio Cirac
We derive a criterion to determine when a translationally invariant matrix product state (MPS) has long-range localizable entanglement, where that quantity remains finite in the th…
Joint system quantum descriptions arising from local quantumness
Tom Cooney, Marius Junge, Miguel Navascues +2
Bipartite correlations generated by non-signalling physical systems that admit a finite-dimensional local quantum description cannot exceed the quantum limits, i.e., they can alway…
Quantum Steering and Space-Like Separation
Miguel Navascues, David Perez-Garcia
In non-relativistic quantum mechanics, measurements performed by separate observers are modeled via tensor products. In Algebraic Quantum Field Theory, though, local observables co…
Matrix Product States, Random Matrix Theory and the Principle of Maximum Entropy
Benoit Collins, Carlos E. Gonzalez-Guillen, David Perez-Garcia
Using random matrix techniques and the theory of Matrix Product States we show that reduced density matrices of quantum spin chains have generically maximum entropy.
