Future quantum technologies may exploit identical particle entanglement

Usually when physicists perform quantum entanglement between particles--whether it be qubits, atoms, photons, electrons, etc.--the particles are distinguishable in some way. Only recently have physicists demonstrated the feasibility of generating entanglement between particles that are completely identical. Interestingly, this entanglement exists just because of the indistinguishability of the particles, without any interaction between them.
