Quantum-optical spin glass
Rubidium atoms wired together by photons realize spin glasses and quantum neural networks.
What is a quantum neural network and how might it exhibit computational advantage? Can we create a spin glass made of atomic spins and photons and use it to resolve longstanding mysteries surrounding spin-glass order? We are tackling these fundamental and technologically relevant questions using our novel multimode cavity QED-BEC apparatus. The system provides strong, photon-mediated interactions among atoms trapped within the cavity resonator. Photons virtually scattered among the atoms cause the system to superradiate and self-organize into various exotic forms of quantum matter such as quantum spin glasses---which can be used as quantum neural networks and associative memories. We recently created a supersolid that vibrates by forming an optical lattice with sound.
