We propose a measurement protocol to generate quantum entanglement between two remote qubits, through joint homodyne detection of their spontaneous emission. The entanglement yield corresponds to our ability to erase the emission source information by using a balanced beam splitter, and choosing a particular phase relationship between the quadratures we monitor at each output. We investigate the diffusive quantum trajectories from this process, and predict that such a scheme can create maximally--entangled states of the two qubits, when the local oscillators are ninety degrees out of phase.
