Entanglement of Inhomogeneous Free Bosons and Orthogonal Polynomials
Pierre-Antoine Bernard, Rafael I. Nepomechie, Gilles Parez +3
In this paper, we investigate the ground-state entanglement entropy in inhomogeneous free-boson models in one spatial dimension. We develop a powerful method to extract the leading…

Dicke states as matrix product states
David Raveh, Rafael I. Nepomechie
We derive an exact canonical matrix product state (MPS) representation for Dicke states with minimal bond dimension , for general values of and , for…

Deterministic Bethe state preparation
David Raveh, Rafael I. Nepomechie
We present an explicit quantum circuit that prepares an arbitrary -eigenstate on a quantum computer, including the exact eigenstates of the spin-1/2 XXZ quantum spin chain wi…
