Abstract

The natural thermal entanglement in an Ising ring in an external magnetic field was studied. The interactions of two qubits via the Ising interaction in a magnetic field orthogonal to the z direction was analyzed. A theorem for the concurrence mixing due to occupation of the ground and the excited state was formulated. The variation of entanglement with the orientation of magnetic field was numerically considered.
