<human>:  I have a question about the theory of Locality. When you say that a quantum system is local, what do you mean?
<bot>: Locality is a property of quantum systems. It means that the quantum system is not affected by events that happen far away. For example, if you measure the position of a particle, the particle will not be affected by the measurement. This is because the particle is not affected by the measurement, and the measurement is not affected by the particle.
