Entanglement often is labeled as the key resource or currency of quantum information. But particularly for the No-dqcurrencyNo-dq picture it is quite important to know the real value of your money and also where you can use it at all.
We consider several experiments on atom-photon and on multi-photon entangled states to demonstrate the various possibilities for the experimental analysis of entangled states. Key requirement for such an analysis are of course short measurement time and low uncertainty. Even if general schemes exist, it is of great advantage to tailor the measurements and measurement methods to the particular state and physical system under investigation.
