Can more than two be entangled?
How do you entangle in the first place?
Yes. Even when initially unentangled, any interaction between two particles will immediately lead to entanglement.rpthomps said:Can all types of particles be entangled?
Yes, that's technically true even in situations where that entanglement consists of nothing more than conservation rules. But is it then fair to say that they were not entangled prior to interaction when the conservation rules still applied? Or how about forward elastic scattering of spinless particles where no particle changes its state? In fact, if they were some long term consequence of some primeval "big bang" (or many worlds history) then were they not already entangled by previous interaction -- however insignificant that entanglement may be for their state prior to interaction?A.

The end of loneliness. How so very zen.StevieTNZ said:From the various Professors of Physics (including Professors of Philosophy, specialising in Philosophy of Physics) I've written to about this, as well as information in different books, they've all stated everything is entangled with everything else.
This is indeed the case, unless you prepare special initial conditions for a few degrees of freedom to which the discussion is restricted, and you ensure that, for some time, these are preserved by the interaction. Thus there is almost no freedom to choose.mikeyork said:1) employ the very general idea that everything is entangled with everything else
Particle entanglement is a phenomenon in quantum mechanics where two or more particles become connected in such a way that the state of one particle is dependent on the state of the other particle, regardless of the distance between them.
Particle entanglement occurs when two or more particles interact or are created in such a way that their quantum states become correlated. This can happen through various methods, such as through collisions or interactions with other particles.
Yes, particle entanglement can occur between any number of particles. However, the more particles that are entangled, the more complex the quantum system becomes.
Particle entanglement is significant because it allows for the transfer of information and properties between particles instantaneously, regardless of the distance between them. This has potential applications in quantum communication and computing.
Yes, particle entanglement has been extensively studied and demonstrated in various experiments. It is a well-established concept in quantum mechanics and has been verified through numerous experiments and observations.
