Precise, High-throughput Analysis of Bacterial Growth Masaomi Kurokawa1, Bei-Wen Ying1,2 1Graduate School of Life and Environmental Sciences, University of Tsukuba, 2Institute of Biology and Information Science, East China Normal University Quantitative evaluation of bacterial growth is essential to understanding microbial physiology as a systems-level phenomenon. A protocol for experimental manipulation and an analytical approach are introduced, allowing for precise, high-throughput analysis of bacterial growth, which is a key subject of interest in systems biology.
Quantum State Engineering of Light with Continuous-wave Optical Parametric Oscillators Olivier Morin1, Jianli Liu1, Kun Huang1,2, Felippe Barbosa3, Claude Fabre1, Julien Laurat1 1Laboratoire Kastler Brossel, Université Pierre et Marie Curie, Ecole Normale Supérieure, CNRS, 2State Key Laboratory of Precision Spectroscopy, East China Normal University, 3Instituto de Física, Universidade de São Paulo We describe the reliable generation of non-Gaussian states of traveling optical fields, including single-photon states and coherent state superpositions, using a conditional preparation method operated on the non-classical light emitted by optical parametric oscillators. Type-I and type-II phase-matched oscillators are considered and common procedures, such as the required frequency filtering or the high-efficiency quantum state characterization by homodyning, are detailed.
