Abstract
We present an entanglement verification method for systems with underlying qubit-mode structure, which does not require full knowledge of the bi-partite density matrix. It is applied to a quantum key distribution experiment with coherent signal states and one of two different detection schemes: For heterodyne detection, it is possible to detect entanglement even in the presence of loss and noise whereas for Stokes operator measurements, entanglement verification fails.
