Concept

No-communication theorem

The image depicts a network of interconnected spheres, symbolizing the concept of entanglement in quantum information theory, where measurement outcomes on one particle affect another, demonstrating the no-communication theorem.

A formal result in quantum information theory showing that entangled particles cannot be used to transmit information faster than light. Measurement outcomes on one side are statistically independent of what the other party does until classical channels are used to compare notes. The theorem is what allows quantum mechanics and special relativity to coexist without paradox.
