One-way gates based on EPR, GHZ and decoherence-free states of W class

The logical gates using quantum measurement as a primitive of quantum computation are considered. It is found that these gates achieved with EPR, GHZ and W entangled states have the same structure, allow encoding the classical information into states of quantum system and can perform any calculation...

Summary:The logical gates using quantum measurement as a primitive of quantum computation are considered. It is found that these gates achieved with EPR, GHZ and W entangled states have the same structure, allow encoding the classical information into states of quantum system and can perform any calculations. A particular case of decoherence-free W states is discussed as in this very case the logical gate is decoherence-free.
