Quantum information consists of three blocks: quantum communication, quantum computing, and quantum precision measurement.
This video is an excerpt from the live broadcast of Professor Yuan Lanfeng on the theme of "Principles and Technologies of Quantum Information" on September 11, 2021
(Why has quantum, which was proposed a hundred years ago, suddenly become a hot topic |? Technology Yuan Ren)

What does specific quantum information include? You can think about it, what does the information technology we usually use include? The most used is the mobile phone, right? Mobile phones are used to communicate, and then there are computers, computers are used to do calculations, and then we usually use things like rulers, thermometers, clocks and watches, in fact, can also be counted as information technology, they are used to make measurements, right?
So correspondingly, quantum information also includes such three blocks, that is, quantum communication, quantum computing and quantum precision measurement.
Then in these three blocks, each of which includes some specific technologies, such as quantum communication including quantum cryptography and quantum teleportation, this quantum teleportation state is what I just said teleportation, quantum computing includes quantum factor decomposition, or quantum search, and then quantum precision measurement, including atomic clocks and quantum radar, etc., and then we will explain these three blocks separately.
Among these three blocks, the easiest to understand is quantum precision measurement, because you don't need to understand its principles, you only need to understand one thing, that is, through this quantum mechanical technology, we can measure certain physical quantities much more accurately than before, you improve the measurement accuracy, of course, you can do a lot of things that you couldn't do before, right? It's obvious, so this thing is the easiest to understand.
