So if photons are Bosons and can get entangled then can all the other Bosons be entangled too?

Question

So if photons are Bosons and can get entangled then can all the other Bosons be entangled too?

Answer 1

The simple answer is yes, but entanglement is notoriously difficult to preserve.  Once you "look at" or in some way measure part of a system, it's entanglement to the rest of the system is destroyed.  This is why entanglement almost only exists in specially controlled laboratory settings.

Also, it's not necessary to be a boson to be entangled.  Electrons aren't bosons but they can be entangled.  Again, though, it's difficult to create and maintain such a system.
