British media said that technical experts warned that with the development of computers, the current encryption methods used to protect everything from financial transactions to military secrets may soon fail. According to a report by the British Science News website on February 26, a physicist and a physicist led by Xiaoqin Elaine Lee, a professor of physics at the University of Texas at Austin in the United States on February 26 The team of engineers issued a report saying that they developed a material with luminescent properties that may prevent hacker communications.
The researchers claim that this material contains thousands of identical "single photon emitters." If confirmed, this new light source can be used as part of a new anti-hacking method. Other researchers have developed single-photon emitters, but previous technologies have not been able to produce a batch of thousands of identical emitters.
To ensure communication security, information has to be encrypted before it is sent. The receiver needs a key to decipher the encrypted information. In some forms of cryptography, the sender sends one photon at a time when transmitting the key. Because photons are the smallest energy unit of light, they can no longer be divided. If the hacker intercepts the photon and tries to read the information, the key will change, and then the receiver will easily find out. This is why efficient single photon emitters are useful in quantum communication applications, and are increasingly necessary. Because advances in computing require more sophisticated means to ensure communication security.
