A nonhomogeneous perturbation superposed to an homogeneous stable fixed point can be amplified following the Turing mechanism of instability, solely instigated by the network dynamics. By properl...

Weitz, and Michael P. Brenner The relationship between the microstructure of a porous medium and the observed flow distribution is still a puzzle. We resolve it with an analytical model, where the local correlations between adjacent pores, which determine the distribution of flows propagated from one pore downstream, predict the... [Phys. Rev.

The Holevo quantity, and hence the mutual information, is at most of order$E\mathrm{Δ}t/ℏ$, where$E$is the average energy of the signal, and$\mathrm{Δ}t\$ is the amount of time for which det...

Extracting Entanglement Geometry from Quantum States

2017-10-02T10:00:00+00:00

Author(s): Katharine Hyatt, James R. Garrison, and Bela Bauer

Tensor networks impose a notion of geometry on the entanglement of a quantum system. In some cases, this geometry is found to reproduce key properties of holographic dualities, and subsequently much work has focused on using tensor networks as tractable models for holographic dualities. Conventional...
