Entangling two particles requires them to interact in a specific manner, typically necessitating their proximity for interaction. Common methods include using indistinguishable particles, such as photons entangled through Parametric Down Conversion, or entangled electrons within a helium atom. The discussion also highlights that entanglement can occur between different types of particles, as long as they are in different states, and emphasizes that entanglement is fundamentally a property of the system rather than the individual particles. Conservation laws often play a role in entanglement processes, but they are not strictly necessary for the phenomenon to occur. Overall, the conversation underscores the complexity and variety of approaches to achieving entanglement in quantum systems.
