Bro cyber: will you be bugged? Transmitting a confidential document via the internet, and being stolen on the way ... In modern society, information security is increasingly being addressed. Is there an inexplicable form of confidentiality that would make the information transmitted absolutely secure and reliable? In recent years, the rapid development of quantum communication technologies is making dreams a reality. Let's talk about quantum communication。
Quantum communication? What kind of technology is this
Cybershinko: quantum communication is a form of communication using quantum mechanics to manipulate a quantum state. It uses quantum mechanics to manipulate the quantum state, interacts with information between the two locations and fulfils tasks that traditional communications cannot perform. It is worth mentioning that quantum communication is the only means of communication so far that has been strictly and unconditionally secure and that can effectively address information security issues。
I don't understand. Can you be more specific
No problem. Quantum is the smallest unit of physical mass, energy, etc. It's got two amazing skills: a biography and a telekinetic. Don't underestimate these two skills, but they're the key to quantum communication。
Quantums, like sun goku, can be divided and can exist simultaneously in two different spaces. But what's different from sun goku's dosage is that, in a quantum world, quantum dosages are not visible, and once someone looks at it, the alternation disappears randomly, leaving only one. Another great tele-psychiatry called quantum tangle. If there is a “touching” relationship between the two quantums, no matter how far apart, when the state of one quantum changes, the other quantum changes accordingly。
Students: what is the principle that quantum is used to secure communications
Bro nano: for the moment, two direct applications of quantum insulation are classified quantum communications. Researchers use both quantum characteristics to make safe and confidential keys. The quantum key is to co-create between a and b a series of random numbers that are known only to both of them and then encrypt them with this random number. Once the quantum key is intercepted or measured, its own state changes immediately. The person who intercepts the quantum key can only get invalid information, and the legitimate recipient of the information can learn from the change in the quantum state that the quantum key was intercepted。
Students: no wonder quantum communication is safe communication. How are we doing in the area of quantum communication
Bro nobu: in recent years, my country has achieved a number of important results in the area of quantum communication and is among the world's leaders. In august 2016, our country successfully launched the world's first quantum science experiment satellite, the ink, and completed a number of scientific experimental objectives; in november 2016, the quantico secrecy communication backbone, the kyogi main line, was successfully launched; and in june 2017, the china communications standardization association established an ad hoc task force on quantage communication and information technology, which launched national standard research。
Students: there are great prospects for quantum communication. Can we use quantum communication in our daily lives
Cyberbro: available. For example, secure transmission of information, if a quantum network is constructed using quantum communication, secure text, voice, video transmission can be achieved without fear of theft. If financial information is transmitted, each user is equipped with a unique "quant id" that can effectively prevent "code theft and bank card brushing"。
Students: this is a great application, so i'm not worried about the bank card being stolen。
On-line: internet shopping is a security precaution. Quantum communication, while already being used in finance, government systems, etc., will take 10 to 15 years to be used by everyone. This requires the adaptation of network infrastructure and involves standard-setting. By that time, individual online banks, mobile phone payments, credit cards, etc. Would no longer fear theft。
Students: while waiting, i am impressed by the magic of quantum communication and i look forward to its early application in life。
Cyberbro: the world of quantum communication, looking at a lot, let's expect scientists to discover more new results in quantum communication。
