"cold crystalline atomic gas... 2X ability program interactions between atoms... metals, insulators, and superconductors... unitary Fermi gas placed optical cavity interact at long distance, 1st atom emit photon bounces onto mirrors, reabsorbed by 2nd atom... atoms collectively organize density wave pattern... combined atoms colliding directly with each other exchanging photons over long distanc... efficient energy transfer and storage, quantum computers"
