Sorry to be facetious but even the most mundane antiferromagnet has an entangled ground state; you can't do anything remotely interesting in solid state physics without the fact of entanglement.Has solid state entanglement been demonstrated before?

Regarding solid state QIP, I defer to f95toli's reply.
Solid state quantum entanglement is a phenomenon in which two or more particles become connected in such a way that the state of one particle is dependent on the state of the other, regardless of the distance between them. This means that changes in one particle will affect the other, even if they are separated by great distances.
Solid state quantum entanglement refers specifically to the entanglement of particles in solid state materials, such as crystals or semiconductors. This is different from regular entanglement, which can occur in various systems, including photons and atoms.
Solid state quantum entanglement has potential applications in quantum computing, quantum communication, and quantum sensing. It could also be used to create more secure forms of communication and encryption.
Solid state quantum entanglement can be created through a process called quantum entanglement swapping, in which two initially unentangled particles interact with a third particle that is entangled with another particle. This results in the two original particles becoming entangled with each other.
One of the main challenges in studying solid state quantum entanglement is maintaining the entanglement over a long distance. Another challenge is controlling and manipulating the entangled particles in a solid state material. Additionally, there are technical challenges in measuring and interpreting the entangled states of particles in solid state systems.
