For the first time in history! Chinese scientists successfully achieve counterfactual quantum communication

Compared with traditional communication methods, quantum communication has become a major direction for future communication development with ultra-high security. Quantum communication, which was often reported before, is based on the principle of entanglement. Today we are going to introduce a more weird form- Counterfactual communication: There is no quantum transmission of particles between two receivers. This effect of not sending particles to transmit quantum states is also called the quantum Zeno effect.
According to a recent report from the Physicist Organization Network, researchers at the University of Science and Technology of China successfully implemented direct counterfactual quantum communication, transmitting a black and white bitmap from one location to another without sending any physical particles. This is in the history of communication This is the first time. The research was designed and experimented by Chinese scientists at the University of Science and Technology Shanghai and Hefei, and Tsinghua University. The nested quantum Zeno effect was used to successfully achieve counterfactual communication.
The quantum Zeno effect occurs repeatedly in unstable quantum systems. In the quantum world, observing or measuring a system will cause the system to change. In this example, unstable particles will never decay when repeatedly observed. The quantum Zeno effect creates a virtually frozen system with a high probability. The research report was published in the Proceedings of the National Academy of Sciences.
