Violation of Bell inequality with unentangled photons
Violation of the Bell inequality can be achieved with quantum indistinguishability via path identity, instead of entanglement.

Finding decoherence-free subspaces in Markovian quantum systems is computationally intractable, even for quantum computers. New QMA-hardness results suggest fundamental limits to verifying quantum error correction structures.
