Abstract

The present invention relates a system for preparation and unitary transformation of quantum states. This system performs transformations quickly in time by regular polarisation transformers. Another advantage of the system of the present invention is able to control all polarisation states, which are necessary to implement the protocol and can be realised by regular polarisation elements.
