Abstract

A polarisationentangled fourphoton state can be generated directly by a second order parametric downconversion process We use this emission to characterise the properties of a fourqubit state and to analyse its entanglement based on the violation of a fourparticle Bell inequality The observed high count rates and the fidelity of the polarisation correlations are the basis for the realisation of several new multiparty quantum communications schemes such as secure multiparty key distribution and quantum telecloning
