Quantum Correlated Four-Wave-Mixing- Cluster States and Cavities
Abstract
Four-wave mixing (4WM) in Rb vapor, under certain circumstances, has been shown to generate quantum-correlated (squeezed) light. The large gain of this system has allowed most of the existing experiments to be performed using a single-pass through the gain medium. We propose to continue our studies of 4WM in Rb vapor in such non-cavity situations for the generation of entangled continuous-variable sensor networks and for the construction of entangled cluster-states of the type used for one-way quantum computing. By adding an external cavity to the system one can take advantage of the strong nonlinearity in additional ways. We propose to explore theoretical predictions of the generation of single-mode squeezing of each of the beams in a twin-beam (2-mode squeezing) system. We have recently discovered ways in which phase-conjugate optics based on the same entanglement-producing 4WM process can be incorporated in our optical system, creating intrinsically-stable resonators. We propose to use this as a model system in which to explore the generation of dissipative Kerr solitons in a tunable OPO. This system is highly tunable in dispersion and, while the small bandwidth will limit applications, the relatively slow pulses will allow for soliton studies in the time domain that are impractical in large bandwidth microresonator systems.
