Abstract

We define and calculate the Schmidt polarization fluctuation of a qubit entangled with an arbitrary environment in a bipartite pure state. It is found that this polarization fluctuation preserves majorization and thus can partially order qubits. We propose that this quantity can be used as an experimentally accessible entanglement measure.
