Ultra-wide-band and ultra-high-speed distance limit-free quantum communication method

Abstract

The invention discloses an ultra-wide-band and ultra-high-speed distance limit-free quantum communication method and belongs to the field of quantum communication. The key point of the technical scheme is that through utilization of a binary information coding principle and a quantum instantaneous transmission characteristic, a plurality of quantum entanglement pairs are sorted from high orders to low orders; quanta are separately stored in quantum state source memories of a sender and a receiver; corresponding marking is carried out; starting from the first high orders of the quantum state source memories to the low orders, one quantum with a quantum state 1 or 0 in every two adjacent, continuous and non-repeated orders is in one to one correspondence with the digital information 1 or 0 of a plurality of pieces of binary information from the high orders to the low orders; the sender operates the quantum state source memory to cause the states of the quanta to be changed; and the receiver obtains instantly collapsed entangled quantum state and / or quantum state sequence information and extracts and stores the binary information therefrom. The method is mainly applied to ultra-wide-band and ultra-high-speed distance limit-free quantum communication.

Description

technical field [0001] An ultra-wideband, ultra-high-speed, and unlimited-distance quantum communication method belongs to the field of quantum communication, and specifically belongs to an ultra-wide-band, ultra-high-speed, and non-distance-limited 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 int...

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
