Quantum communication method

Abstract

The invention discloses a quantum communication method, belongs to the field of communication and particularly belongs to quantum communication with ultra-wideband, ultra-high speed and no distance limitation. The key points of the technical scheme are as follows: sequencing a plurality of quantum entanglement pairs from a high bit to a low bit by utilizing a binary information coding principle and quantum instantaneous transmission characteristics, storing the quantum entanglement pairs in quantum state source memories of a sending side and a receiving side separately and respectively, and correspondingly marking the quantum entanglement pairs; enabling one quantum with the quantum state as 1 or 0 in each two adjacent, continuous and unrepeated bits from the high bit to the low bit of each quantum state source memory to be respectively in one-to-one correspondence with digital information 1 or 0 from the high bit to the low bit of a number of binary information; operating the quantum state source memory thereof by the sending side to change the quantum state; obtaining an instantly collapsed tangled quantum state and / or quantum state sequence information, extracting binary information therein and storing the binary information by the receiving side; and recovering the quantum states of the sending side and the receiving side into an original maximum entangled state by a quantum state recovering machine. The quantum communication method is mainly used for instantaneous quantum communication.

Description

technical field [0001] The method of the invention belongs to the field of quantum communication, and specifically belongs to a quantum communication method. Background technique [0002] Quantum communication refers to a new type of communication method that uses quantum entanglement effect to transmit information. Quantum communication is a new interdisciplinary subject developed in the past two decades, and a new research field combining quantum theory and information theory. Quantum communication mainly involves: quantum cryptography communication, quantum teleportation and quantum dense coding, etc. Recently, this subject has gradually moved from theory to experiment and to practical development. Efficient and secure information transmission has attracted increasing attention. Based on the basic principles of quantum mechanics, it has become an international research hotspot in quantum physics and information science; [0003] Optical quantum communication is mainly ...

Problems solved by technology

[0006] First, what quantum entanglement determines is only the entanglement relationship between two quanta, but the state of the specific two quanta is not static, as long as one of the particles changes state, the other will change immediately, and this change is instantaneous, As of 2013, the technology cannot detect any signal transmission between the two particles. There is no experiment to prove the connection between them. Some people think it is some kind of mysterious signal, and some people think it is inherent in the universe. However, experiments can prove that if it is some kind of mysterious signal that makes the connection between them, its transmission speed is much faster than the speed of light. Since any energy of this "signal" cannot be detected, this phenomenon and special relativity Whether there is opposition between them cannot be simply concluded;

[0007] Second, as of 2013, quantum communication cannot exceed the speed of light, but this does not mean that the state transmission speed of quantum itself cannot exceed the speed of light. The reason why quantum communication cannot exceed the speed of light is determined by the level of research and understanding. As of 2013 Research shows that quantum state transfer cannot carry any information, that is to say, quantum state transfer cannot be used as a carrier wave in classical communication. This reality makes quantum communication cannot exceed the speed of light. No one can draw conclusions about how it will develop in the future
