What is the optimal way to entangle a multi-partite quantum system by exploiting the interaction between various parts? (Given a system, interaction between its parts is also given). A quantum system evolves to generate entanglement provided its parts interact. Questions 1.Given an interaction (Hamiltonian) what is the most efficient way of entangling particles? 2.Can we make the process more efficient by supplementing the action of the Hamiltonian with some local unitary operations? 3.Can we increase the entanglement more efficiently by using ancillas?
Two Qubit Case • The effective interaction Hamiltonian is • Where are the sorted singular values of the matrix.
