Deformed Fredkin Spin Chain with Extensive Entanglement
Olof Salberger, Takuma Udagawa, Zhao Zhang +3
We introduce a new spin chain which is a deformation of the Fredkin spin chain and has a phase transition between bounded and extensive entanglement entropy scaling. In this chain,…

Fredkin Spin Chain
Olof Salberger, Vladimir Korepin
We introduce a new model of interacting spin 1/2. It describes interaction of three nearest neighbors. The Hamiltonian can be expressed in terms of Fredkin gates. The Fredkin gate…

Violation of Cluster Decomposition and Absence of Light-Cones in Local Integer and Half-Integer Spin Chains
L. Dell'Anna, O. Salberger, L. Barbiero +2
We compute the ground state correlation functions of an exactly solvable chain of integer spins, recently introduced in [R. Movassagh and P. W. Shor, arXiv:1408.1657], whose ground…
