Quantum information, quantum communication and innovation

Leilei Zhang, Jian Kang, Zhonghu He

Against the backdrop of intensified global competition in quantum information, the synergistic effectiveness of quality infrastructure, as a basic system supporting industrial innovation, is directly related to the industrialization process of quantum technology. At present, subdivided industries such as quantum computing, quantum communication, and quantum precision measurement have begun to take shape, and key technologies and core products have entered a critical period of transition from scientific and technological innovation results to industrialization, and the demand for quality infrastructure is becoming increasingly prominent. This study explores the co-evolution mechanism of quality infrastructure driven by industrial innovation and analyzes the coupling effect of quality infrastructure on industrial innovation. Identified targeted issues in the quality infrastructure construction of quantum computing, quantum communication, and quantum precision measurement through the survey. It proposes targeted pathways for the collaborative innovation of quality infrastructure and industry from multiple dimensions, including standard leadership, inspection and certification assurance, metrological support, and collaborative problem-solving models.

The development of technology is progressing towards the merger between digital technologies and physical systems. Furthermore this includes the shift towards quantum information science and the development of quantum technology. Quantum communication and quantum computer are the two main research areas of quantum information science. Here, we focus on the development of quantum encryption over the years and the innovation behind building an automated portable single photon entanglement source for quantum communication.

In this chapter, I will show that information-transmission (IT) can be carried out within a quantum unit, as defined by the Heisenberg Uncertainty Principle, in which this unit can be translated as a quantum limited subspace (QLS). We will show that the size of a QLS is determined by the carrier bandwidth; that is, the narrower the bandwidth, the larger the size of the QLS can be used for complex amplitude communication. By understanding the pros and the cons of IT within the QLS, more innovative communication techniques can be developed and employed in practice, for example, as applied to security IT within the QLS. Imaging using phase conjugation idea will be illustrated. A new era of innovative communication is anticipated to emerge and it will change the way we used to communicate forever!
