Quantum computation algorithm for many-body studies
E. Ovrum, M. Hjorth-Jensen
We show in detail how the Jordan-Wigner transformation can be used to simulate any fermionic many-body Hamiltonian on a quantum computer. We develop an algorithm based on appropria…

Extreme points of the set of density matrices with positive partial transpose
Jon Magne Leinaas, Jan Myrheim, Eirik Ovrum
We present a necessary and sufficient condition for a finite dimensional density matrix to be an extreme point of the convex set of density matrices with positive partial transpose…

Geometrical aspects of entanglement
Jon Magne Leinaas, Jan Myrheim, Eirik Ovrum
We study geometrical aspects of entanglement, with the Hilbert--Schmidt norm defining the metric on the set of density matrices. We focus first on the simplest case of two two-leve…
