How does quantum entanglement enable faster-than-light communication?

Asked on Dec 07, 2025

Answer

Quantum entanglement does not enable faster-than-light communication, as it does not transmit information in a way that violates the principles of relativity. Instead, entanglement is a quantum phenomenon where two or more particles become correlated in such a way that the state of one particle instantly influences the state of the other, regardless of the distance between them.

Example Concept: Quantum entanglement involves creating a pair of particles in a joint quantum state such that the measurement of one particle's state immediately determines the state of the other. However, this correlation does not allow for communication of information faster than light because the outcome of measurements is inherently random, and classical information is required to compare results and verify entanglement.

Additional Comment:

Entanglement is used in quantum key distribution (QKD) to ensure secure communication, not faster-than-light transmission.
Bell's theorem and experiments confirm entanglement's non-local properties but uphold the no-signaling principle.
Quantum teleportation, which uses entanglement, requires classical communication to complete the process.
