What is quantum technology?

Let's take a look at what "quantum" is. Quantum is actually "the smallest unit of discrete change". What is discrete change? This is a mathematical concept. For example, if we want to count an animal, we can have one cat, two cats and three cats, but you can't have half a cat. Another example is counting the number of people in the mall. One person, two people and three people. There can't be half a person, one third of the people and so on. If something can only change discretely, we say it is "quantized".

In fact, quantum technology is also a variety of development technologies of quantum information.

At present, quantum technology mainly has four application fields: quantum communication, quantum calculation, quantum simulation, quantum sensing and measurement. At present, China's quantum communication technology research and development and industrial innovation achievements are in the forefront of the world and belong to the first echelon in the world. Quantum communication is a communication technology that uses quantum states as information carriers to exchange information. In principle, it ensures that unauthorized parties cannot copy and steal the information transmitted in the quantum channel. In the long run, industrial application scenarios are very extensive, including network information security, quantum communication trunk lines, quantum metropolitan area networks, finance, national defense and so on.
