Abstract
We propose a method to measure the entanglement of nearby spins by means of multiphoton correlation interference patterns generated by the scattering of two perpendicular pulsed laser beams with opposite circular polarization. As this method is based on optical read-out only, it provides the possibility to monitor with minimal intrusion the evolution and the decoherence of many-spin entanglement. This method is capable of retrieving all the amplitudes of a general many-spin state of arbitrary dimension. Explicit calculations are presented for a quantum dot spin system.
