Ever! Chinese scientists have successfully implemented counterfactual quantum communication


Compared with traditional communication methods, quantum communication has become a major direction of future communication development with ultra-high security. Previously, quantum communication, which is often reported, is based on the principle of entanglement. Today, we will introduce a more eccentric form - counterfactual communication: Quantum communication in which no particles are transmitted between two receivers, this effect of transmitting quantum states without sending particles, is also known as the quantum Zeno effect.

According to a recent report by the Physicist Organization network, researchers at the University of Science and Technology of China have successfully realized direct counterfactual quantum communication, transmitting a black and white bitmap from one location to another without sending any physical particles, which is unprecedented in the history of communication. The study, designed and experimented by a collaboration of Chinese scientists at the University of Science and Technology of China in Shanghai and Hefei, and Tsinghua University, successfully implemented counterfactual communication using nested quantum Zeno effects.

The quantum Zeno effect occurs when unstable quantum systems are repeatedly measured. In the quantum world, observing or measuring a system causes the system to change, and in this case, unstable particles will never decay when repeatedly observed. The quantum Zeno effect creates a de facto frozen system with a high probability. The study was published in the Proceedings of the National Academy of Sciences.
