1, quantum satellite
It is used to transmit quantum signals on demand. This is a communication satellite. Because the carrier photon of quantum signal has almost no loss when propagating in outer space, if it can be technically realized that entangled photons can survive and maintain their entangled characteristics after penetrating the whole atmosphere, people can realize global quantum communication with the help of satellites. Simply put, the signal is good.
2. Quantum computer
It is a physical device that follows the laws of quantum mechanics, performs high-speed mathematical and logical operations, and stores and processes quantum information. When a device processes and calculates quantum information and runs quantum algorithms, it is a quantum computer. The concept of quantum computer comes from the research of reversible computer. The purpose of studying reversible computers is to solve the energy consumption problem of computers.
3. Quantum communication
It refers to a new communication method that uses quantum entanglement effect to transmit information. Quantum communication has the characteristics of high efficiency and absolute security, so it has become the research hotspot of quantum physics and information science in the world.
Quantum computer is a computer based on quantum theory. Tracing back to the source, it is the continuous exploration of reversible machines that promotes the development of quantum computers. Quantum computer devices follow the basic theory of quantum computing, process and calculate quantum information, and run quantum algorithms. 198 1 year, Paul Benioff of Aragon national laboratory in the United States first put forward the basic theory of quantum computing.
