An entangled pair refers to two particles that are connected in such a way that their properties are dependent on each other, even when separated by large distances. This phenomenon is a key aspect of quantum mechanics and has been experimentally proven.
The particles in an entangled pair are connected through a quantum state known as superposition. This means that the particles exist in all possible states simultaneously until they are observed or measured, at which point they collapse into a single state.
The concept of entangled pairs is closely tied to the speed of light because the particles in an entangled pair can influence each other instantaneously, regardless of the distance between them. This goes against the limitations of the speed of light as the maximum speed at which information can travel.
No, entangled pairs cannot be used to communicate faster than the speed of light. Although the particles in an entangled pair can influence each other instantly, this does not violate the principles of relativity or allow for faster-than-light communication.
Entangled pairs have potential applications in quantum computing, cryptography, and teleportation. They could also potentially lead to new technologies for secure communication and information processing.
