When two particles are entangled, their quantum states become correlated, regardless of the distance between them. This means that measuring the state of one particle can instantaneously affect the state of its entangled partner, even if they are separated by vast distances. This phenomenon is known as quantum entanglement.
If one of the entangled particles is destroyed or its state is altered, it does not immediately affect the other entangled particle. However, the entanglement between the particles is disrupted or broken. As a result, any correlations or dependencies that existed between their states are lost. The remaining particle will no longer exhibit any entanglement with the destroyed or altered particle.
It's important to note that the exact consequences of destroying or altering an entangled particle depend on the specific experimental setup and the nature of the particles involved. In general, the destruction of one entangled particle does not directly cause any instantaneous change in the other entangled particle, but it does break the entanglement between them.
