| 1:45pm-2:30pm | Pete Shadbolt, University of Bristol (invited) | Integrated quantum photonics | Abstract. |
| 2:30pm-3:00pm | Michael Raymer, University of Oregon | Quantum Optical Pulse Shaping, Routing, and Frequency Translation by Four-Wave Mixing in Optical Fiber | Abstract. Our collaboration of U Oregon, Bell Labs, and UC San Diego is developing quantum frequency translation (background-free frequency conversion) of quantum states of light by using four-wave mixing in optical fiber. The involvement of two pump pulses at distinct frequencies leads to useful capabilities not present when using single-pump three-wave mixing. It allows pulse reshaping and routing of quantum optical wave packets, including single-photon states. It also allows translating between nearby frequency channels, opening the possibility of quantum-level wavelength-division multiplexing. |
| 3:00pm-3:30pm | Jian Yang, University of Illinois at Urbana-Champaign | Strong Photon-photon Interaction in Cavity-Quantum Dot System | Abstract. The photon plays a critical role in quantum communication and quantum computation. Photon-photon interaction is essential to construct efficient quantum logic gates, but it is typically extremely weak in nonlinear media. Exploiting cavity-quantum dot (C-QD) interactions in the strong coupling regime, we found that photons with ˇ°time-reversedˇ± line-shapes of the C-QD emissions can excite the system with near-unity efficiency. In this way, photons can acquire strong interactions with each other, which may be useful in a variety of quantum information applications, including quantum non-demolition detectors and constructing high-efficiency quantum logic gates. |
