Research status and future of quantum information technology

Abstract

Quantum information technology is an emerging interdisciplinary field of quantum mechanics and information science, whose birth will promote a new era of human intelligence from classical technology to quantum technology. This paper elaborates on the research status and future of the field of quantum information technology. Moreover, this paper shows the vision of quantum technology, i.e., the construction of various types of quantum networks, including quantum cloud computing networks, distributed quantum computing, quantum sensor networks, and quantum key distribution networks. Quantum computers have transformed research from the laboratory to the development of practical devices led by these enterprises. Currently, research and development of quantum computers have shifted to the stage of noisy intermediate-scale quantum computers (NISQ). In the era of quantum technology, there is no absolutely secure secrecy system or omnipotent way of deciphering Information and information security has entered a new stage of “quantum offense and defense.
