Ground State Entanglement in One Dimensional Translationally Invariant Quantum Systems
We examine whether it is possible for one-dimensional translationally-invariant Hamiltonians to have ground states with a high degree of entanglement. We present a family of translationally invariant Hamiltonians {Hn} for the infinite chain. The spectral gap of Hn is Ω(1/poly(n)). Moreover, for any state in the ground space of Hn and anym, there are regions of sizem with entanglement entropy Ω(...
متن کاملSimulating Quantum Computation by Contracting Tensor Networks
The treewidth of a graph is a useful combinatorial measure of how close the graph is to a tree. We prove that a quantum circuit with T gates whose underlying graph has treewidth d can be simulated deterministically in T O(1) exp[O(d)] time, which, in particular, is polynomial in T if d = O(logT ). Among many implications, we show efficient simulations and for log-depth circuits whose gates appl...
متن کاملEntanglement and criticality in translationally invariant harmonic lattice systems with finite-range interactions.
We discuss the relation between entanglement and criticality in translationally invariant harmonic lattice systems with nonrandom, finite-range interactions. We show that the criticality of the system as well as validity or breakdown of the entanglement area law are solely determined by the analytic properties of the spectral function of the oscillator system, which can easily be computed. In p...
متن کاملFermionic systems with charge correlations on the Bethe lattice
A fermionic model, built up of q species of localized Fermi particles, interacting by charge correlations, is isomorphic to a spinq 2 Ising model. However, the equivalence is only formal and the two systems exhibit a different physical behavior. By considering a Bethe lattice with q = 1, we have exactly solved the models. There exists a critical temperature below which there is a spontaneous br...
متن کاملLocal Hamiltonians in Quantum Computation
In this thesis, I investigate aspects of local Hamiltonians in quantum computing. First, I focus on the Adiabatic Quantum Computing model, based on evolution with a timedependent Hamiltonian. I show that to succeed using AQC, the Hamiltonian involved must have local structure, which leads to a result about eigenvalue gaps from information theory. I also improve results about simulating quantum ...
