Kuantum hesaplama için bloch vektör formalismi

The Bloch vector formalism provides a useful approach to both fundamental andapplied problems of the finite dimensional, composite quantum systems, andtherefore it is a very important tool for the research on quantum computation andinformation. This thesis deals with the systematic treatment of Bloch vectorformalism for quantum mechanics of one node, two node and three node systems.Each chapter is divided into three sections dealing with state vectors, measurementsand time evolutions. Also, the geometric picture of the space of states will be givenin the section on one node systems. Classically correlated states i.e. separablestates, for two and three node systems will be investigated in the relevant chapters. Iwill also briefly mentioned the well-known EPR paradox, Bell's inequality, Mermin'sproofs on the problems with the elements of reality by using GHZ state and the twodifferent classes of the genuine tripartite entanglement to comprehend the unusualnature of entanglement.Advisor: Prof. Tekin Dereli Date:Director: Prof. Süleyman Özekici Date:
