Abstract

In this paper we consider feedback control algorithms for the deterministic purification of a bipartite state consisting of two qubits, when the observer has access to only one of the qubits. We show that Hamiltonian feedback control can be used to produce deterministic evolution of the purity of either qubit individually, or both together.
