Lin Li hurried to Xiao Ming's office early in the morning and became the company's rotating chairman. Although Lin Li was no longer responsible for collective business matters, he still grasped the major project deployment decisions of Pangu Ecology and Pangu Future.
The matter of quantum communication was approved a few years ago when the quantum chip came out, and Pangu Future Co., Ltd. has been conducting corresponding experiments.
Quangu Communication Pangu Science and Technology Park has been piloted on a small scale.
At the core of quantum communication is the quantum entangled state. The main components include quantum state generators, quantum channels, and quantum measurement devices.
Quantum satellites are also not new. In the early years, Xia Guo launched an excess of subsatellites. However, because the quantum satellites have fewer entangled bits, they can only be used for special experimental communications and cannot be used for general civilian communications.
But Pangu technology is different. With the application of the quantum chip in the Ming Dynasty, it can master multi-quantum and multi-bit entanglement. This entanglement can already satisfy human daily communication.
Here quantum numbers and bits are different concepts.
Quantum quantity is well understood. In the macroscopic quantum concept, an electron and a photon are all quantum. The "one" here is the quantum quantity.
What about bits?
For example, a quantum has characteristics such as path, polarization, angular momentum, and so on. If these three characteristics are related to each other, then 3 times 6 are equal to 18 bits of entanglement between the six photons (quantums). This is the concept of qubits.
The basic principle of quantum communication is that through certain means, communication satellites, base stations, user terminal equipment, etc., are used to allow certain characteristics of quantum to be entangled in a certain way. After superimposition, multi-quantum, Multi-bit entangled states to meet people's needs for the amount of information.
When quantum information is converted into information that people need, certain measures need to be taken. That is, the quantum measurement device of the terminal device. According to the characteristic of quantum entanglement, there are two ways to obtain quantum information. Measuring quantum entangled states produces perfect copies of the original. In this process, the original material is not transmitted, and the replica is only very similar to the original material. One is in the case of a pair of entangled particles, the sender of the information measures other substances with one of the entangled particles, and the terminal receiver performs a special transformation to create the unknown.
In the future, people will use the above two methods to complete communication tasks on a daily basis. The advantages of quantum communication are instant communication, indecipherability, eavesdropping, non-locality, and so on.
As long as your entangled bits can meet the requirements, in theory, the communication speed can reach the speed of light. The speed of light is basically unlimited for people's daily communication.
In Pangu Science and Technology Park, Pangu Future conducted simulation experiments at the end of last year.
A signal transfer station is set up on the high mountain next to the park, which is to simulate the role of a quantum satellite.
In total, there are three small communication base stations in different locations in the park. The local area network of employees of Pangu Technology Futures Co., Ltd. is also currently completed by quantum communication.
During testing, employees have discovered many of the benefits of quantum communication.
For example, in virtual communities with high network quality requirements, employees using Qinghe devices with upgraded quantum communication components can get in and out almost every second without any delay.
For example, in the depths of the laboratory and other places where communication signals were not good in the past, there is no problem with quantum communication now.
The most critical issue is information security. Quantum communication is used. Except for the sender and receiver of the information, the intermediary cannot steal user information by any means. This will give users great security in the network world where privacy is nowhere to be found. .
Xiao Ming put forward: "Why our public opinion abroad is so passive, because the Internet and communications are not in the hands of Xia Guoren. Even if Warwick can take the lead in 5G communications, it still cannot take the initiative."
Xiao Ming asked Lin Li, "We have no shortage of technology. Now we need to rebuild the Internet and communication ecosystem and firmly take the initiative. This is more useful than letting Xiaochu hack Twitter and Facebook."
Lin Li smiled embarrassedly and said, "I talked to me at the beginning of the day, and I talked casually."
Lin Li gave his own plan, "We can use Jiangcheng as a pilot and first let Jiangcheng citizens use quantum communication."
Changing the way citizens communicate is not as simple as changing a communication terminal or a card. From the point where messages are sent to the point where they are received, a complete communication system needs to be built.
This can start with the Pangu science and technology ecological chain.
The hot sales of Qinghe equipment allow Pangu ecology to be integrated into all aspects of people's lives. If Pangu ecology is started, it can slowly guide people from the traditional communication and network era into the quantum era.
Lin Li said: "We are trying to build a super server in Jiangcheng to move the corresponding content of the ecological chain to the server. In addition, quantum satellites can use the transit station we have already built without going to heaven ~ EbookFREE.me ~. In addition, we only need to upgrade the user ’s Qinghe equipment, so that users do not need to change cards for the time being, and try dual communication in parallel. "
According to the principle of quantum communication, there is no distance limitation for communication, so quantum satellites can be in the sky or on the ground.
The satellite is launched in the sky, in order to prevent it from being artificially damaged, not subject to the wind and rain of nature, to have a longer service life and lower maintenance costs.
At present, Pangu Technology has not reached the time when quantum satellites will occur in the sky, after all, it is only a small-scale test.
Lin Li left Xiao Ming's office and Pangu Technology quietly registered Pangu Quantum Communication Co., Ltd. the next day.
The name is very direct and clear.
Some boring netizens observe the new business of Pangu Technology every day in the "enterprise search", and suddenly find that the newly registered Quantum Communication Co., Ltd. is like a new continent.
In the face of some netizens' questions, Pangu Technology only responded in a low-key manner, which is a trademark for cybersquatting in the future.
In the age of the Internet, which is bursting with news every day, this little doubt is quickly covered by other news.
Pangu Technology's team is working in strict accordance with Lin Li's plan.
The Pangu ecological application developed by Pangu Technology, especially the virtual community, was migrated from the Pangu Technology Group server to the newly formed quantum server.
Lin Li will also build quantum servers in cities with concentrated Internet industries such as Shenzhen, Yanjing, Shanghai, and Rongcheng.
In the future, all application layers of the Pangu ecology can be run on the server and seamlessly interface with the quantum communication network.
Pangu Technology is also in contact with major application-layer companies, and welcomes the other party to lease the Pangu Technology quantum server and put related resources on the server to run.
