Introduction

Quantum mechanics is a fundamental branch of physics which generalizes classical mechanics to provide accurate descriptions for many previously unexplained phenomena such as black body radiation, photoelectric eﬀect and Compton eﬀect. The term quantum mechanics was ﬁrst coined by Max Born in 1924. Within the ﬁeld of engineering, quantum...
