Quantum entanglement and the CHSH game

Measurement and signaling in the nonlocal world Popular understanding of quantum mechanics usually focuses on three learning objectives: At small scales, particle properties (position, momentum, spin, etc.) are in superposition - they don't have a definite value, but instead are “smeared” across multiple possible values. Measuring a superposed particle property makes it collapse probabilistically to a specific value. We don't simply discover the property's pre-existing value; rather the property is forced to take on a definite value by the act of measurement. [Read More]
