In this contribution we will give a brief overview on the methods used to overcome decoherence in quantum communication protocols. We give an introduction to quantum error correction, entanglement purification and quantum cryptography. It is shown that entanglement purification can be used to create ``private entanglement'', which makes it a useful tool for cryptographic protocols.

We discuss the recent developments in exploiting Quantum Optical Correlations in order to overcome the classical limits on measurement. After a general introduction to the argument, we will consider in detail some specific and emblematic protocols, and focus in particular on applications to the holometer.
