Geometric measure of entanglement for pure states and mean value of spin
Andrzej M. Frydryszak, Volodymyr M. Tkachuk
We derive an explicit expression for geometric measure of entanglement for spin and other quantum system. A relation of entanglement in pure state with the mean value of spin is gi…

Qubit, superqubit and squbit
Andrzej M. Frydryszak
We analyze recently proposed formalisms which use nilpotent variables to describe and/or generalize qubits and notion of entanglement. There are two types of them distinguished by…
