Definition and the state-of-art applications of quantum state

Abstract

Quantum mechanics is an important part of modern physics. It is a subject which aims at studying the motion law of microscopic particles. This represents the entry of human physics into the world of the micro. It also marks a fundamentally correct and revolutionary understanding of particle motion at the microscopic level. The study of quantum states is the definition of quantum systems. Quantum states and further processing are important blocks of quantum mechanics. This paper will focus on the definition of different quantum states and the application of quantum state operation will be introduced. To evaluate the application of quantum states from the advantages and limitations in order to achieve a comprehensive and objective display of the full picture of quantum states. This paper describes the specific classification of pure state and mixed state of quantum states, and explains their application and frontier applications as well as their current limitations and shortcomings from the perspective of different quantum states. Overall, these results shed light on guiding further exploration of applications for quantum techniques.
