Can quantum entanglement be used to transmit information between two distant points?
The short answer is no , you cannot send usable (classical) information simply by measuring one half of an entangled pair—at least not in a way that circumvents normal communication channels. Although entangled particles have correlations in their measurement outcomes, these correlations alone cannot be used to transmit messages faster than light or in the absence of a classical signal. Below is a bit more detail on why: 1. Quantum Entanglement in a Nutshell Entanglement is a quantum-mechanical phenomenon where the quantum states of two (or more) particles become linked. Measuring one entangled particle appears to “instantaneously” affect the state of the other, no matter the distance between them. Despite this “spooky” nature, entanglement by itself does not allow you to send classical information (i.e., readable messages) faster than light. 2. The No-Communication Theorem The no-communication theorem in quantum mechanics states that mea...
Loops of Space
Loops of Space Gravity and subatomic forces may both arise from a fine mesh of space-time loops. By Marcia Bartusiak Apr 1, 1993 8:00 AM Nov 12, 2019 5:55 AM
