Is It Possible to Manipulate Quantum Entanglement for Communication?

Quantum entanglement is a phenomenon where two or more particles become linked in such a way that the state of one particle can instantaneously affect the state of another, no matter the distance between them. To grasp this concept, students should first familiarize themselves with quantum mechanics basics and how particles such as photons or electrons can exhibit entangled states.

Explore how quantum communication is based on the principles of quantum mechanics, particularly focusing on entanglement, superposition, and measurement. By using entangled particles, it's theorized that information can be sent securely, as any attempt to intercept the communication alters the state of the entangled particles, thus revealing the presence of eavesdroppers.
