Area laws and tensor networks for maximally mixed ground states
Itai Arad, Raz Firanko, Rahul Jain
We show an area law in the mutual information for the maximally-mixed state in the ground space of general Hamiltonians, which is independent of the underlying ground space deg…
Learning a quantum channel from its steady-state
Yigal Ilin, Itai Arad
We present a scalable method for learning local quantum channels using local expectation values measured on a single state -- their steady state. Our method is inspired by the algo…
Area law for steady states of detailed-balance local Lindbladians
Raz Firanko, Moshe Goldstein, Itai Arad
We study steady-states of quantum Markovian processes whose evolution is described by local Lindbladians. We assume that the Lindbladian is gapped and satisfies quantum detailed ba…
Block belief propagation algorithm for two-dimensional tensor networks
Chu Guo, Dario Poletti, Itai Arad
Belief propagation is a well-studied algorithm for approximating local marginals of multivariate probability distribution over complex networks, while tensor network states are pow…
