What kind of multi-node network?
Multi-node quantum network studied by Chinese scholars.
1. Introduction to quantum network:
Quantum network is a type of physical device that follows the laws of quantum mechanics to perform high-speed mathematical and logical operations, store and process quantum information. When a device processes and calculates quantum information and runs quantum algorithms, it is a quantum network. The concept of quantum networks originated from the study of reversible computers. The purpose of studying reversible computers is to solve the energy consumption problem in computers.
2. Principle:
Send the quantum information of one particle to another entangled particle in the distance. After receiving the information, the particle will become a copy of the original particle. One particle can transmit limited information, and hundreds of millions of particles join forces to form a quantum network.
3. Theoretical basis:
Quantum theory researchers have long discovered quantum entanglement, the key to quantum communication - quantum entanglement.
Quantum entanglement describes such a phenomenon: two microscopic particles are located on both sides of the universe. No matter how far apart they are, as long as the two particles are quantum entangled with each other, by changing the quantum state of one particle, It can change the state of another particle that is very far away. The signal transcends the barriers of time and space and is directly sent to the other particle.
This magical phenomenon is very similar to what we call "telepathy" in our lives. Two people who are far apart want to do the same thing at the same time, as if there is an invisible string holding them. personal.
