Our scientists succeeded in realizing for the first time in history the counterfactual quantum communication

Compared with the traditional methods of communication, quantum communication with high security as the future direction of communications development, often reported quantum communications are based on the principle of entanglement, today to introduce a more weird form - Anti-Fictitious Communication: There is no quantum communication between two recipients for the quantum communication. The effect of not sending the quantum state of the particle transmission is also called the quantum Zeno effect.

According to a recent report by the Physiologist Network, researchers at the University of Science and Technology of China successfully implemented direct counter-factual quantum communication, transmitting a black-and-white bitmap from one location to another without sending any physical particles, For the first time in history. The research was designed and experimented by the Chinese University of Science and Technology, Shanghai Institute of China University of Science and Technology, and Chinese scientists at Tsinghua University to successfully implement counterfactual communication using the nested quantum Zeno effect.

Anti-factual requires a quantum channel between two locations, which means that it is very unlikely that quantum particles will pass through this channel. If they can pass through, they will discard the system and start a new operating system. Because wave-particle duality makes it work, wave-particle duality is the basis of particle physics: Particles can be described individually by wave functions.

In other words, the quantum Zeno effect occurs when the unstable quantum system is repeatedly measured. In the quantum world, observing or measuring systems can cause changes in the system. In this case, unstable particles will never decay when observed repeatedly. The quantum Zeno effect creates a virtually frozen system with a high probability. The study was published in the Proceedings of the National Academy of Sciences.
