Recently, prominent European and American technology giants such as Google, Microsoft, Quantinuum, and Intel have significantly increased their investments in research and development, as well as expanding applications in the realm of quantum computing technology. Among these, InQ, a leading global quantum computing company, has achieved notable advancements in performance, mergers and acquisitions, and external collaborations. Consequently, quantum technology has emerged as one of the most promising avenues in the current technology investment landscape.

01. What is Quantum Technology?

Quantum is a mathematical concept employed to describe the energy characteristics of fundamental particles like photons, protons, neutrons, electrons, and mesons. It represents the smallest unit that can exhibit the properties of a particular substance or physical quantity.

Quantum technology encompasses three primary application areas: quantum communication, quantum computing, and quantum precision measurement. In terms of secure information transmission, computational speed enhancement, and measurement accuracy improvement, it surpasses the limitations of traditional technology and is poised to become a major source of technological innovation in the fields of information, energy, materials, and life sciences, offering core strategic support for national security and the high-quality development of the national economy.

Among these, quantum communication is the field witnessing the fastest pace of practical application, with its industrial chain gradually maturing. Quantum communication utilizes qubits as information carriers for information interaction, surpassing classical information technology's limitations in information security. As the first quantum information technology to achieve practicality and industrialization, the upstream and downstream industrial chain of quantum communication has largely been established.

In China, companies specializing in quantum communication business include Guoke Quantum and Wentian Quantum. Additionally, communication and ICT giants such as China Telecom, State Grid, Toshiba of Japan, SKT of South Korea, Huawei, and China Electronics Technology Group have also established relevant quantum communication research and development teams.

Furthermore, quantum computing technology is continuously making breakthroughs, with vast application prospects. Quantum computers utilize qubits for computation and data storage, featuring unique attributes like quantum superposition and quantum entanglement, enabling them to handle large-scale parallel computing tasks in a remarkably short period.

Google's newly released Willow chip demonstrated an unprecedented quantum advantage in the RCS (Random Circuit Sampling) benchmark test, completing a computational task that would take the most advanced supercomputer 10 trillion trillion years in just 5 minutes. This exemplifies the substantial superiority of quantum computers over traditional computers. According to iCVTA&K's forecast, the global quantum computing industry will grow from $4.7 billion in 2023 to $811.7 billion in 2035.

02. Analysis of Quantum Technology Industrial Chain

In recent years, China's quantum technology industry has made substantial progress. From quantum computing prototypes and quantum communication network construction to quantum precision measurement instruments, a series of significant achievements have continuously emerged. The industrial scale has continually expanded, and the industrial chain has become increasingly comprehensive, showcasing robust innovation vitality and development potential.

Quantum communication is currently the field with the swiftest pace of practical application. In China, technology companies specializing in quantum communication business, such as Guoke Quantum and Wentian Quantum, are leading the way. Additionally, communication and ICT giants such as China Telecom, State Grid, Toshiba of Japan, SKT of South Korea, Huawei, and China Electronics Technology Group have also established relevant quantum communication research and development teams. From an industrial chain perspective, the upstream and downstream of quantum communication have largely been established. The upstream primarily comprises chips, light sources, detectors, quantum random number generators, and other material devices; the midstream includes equipment research and development, manufacturing, network construction, network operation, and services; and the downstream focuses on industry applications. The value of the quantum communication and security industry is primarily driven by quantum physical encryption products and technologies (such as QKD), PQC, QRNG, etc.
