Abstract：
Integrated quantum photonics is an appealing platform for quantum information processing, quantum communication and quantum metrology. In all these applications it is necessary not only to be able to create and detect Fock states of light but also to program the photonic circuits that implements some desired logical operation. I will talk about recent process on our reconfigurable quantum photonics chip project: reconfigurable controlled two-qubit operation on a chip using a multiwaveguide interferometer with a tunable phase shifter. We find excellent agreement between theory and experiment, with a 0.98 ± 0.02 average similarity between measured and ideal operations.
Dr. Hongwei Li简介：
Dr Howgwei Li did his PhD between 1996-2001 on semiconductor material and devices in Institute of Physics, Chinese Academy of Sciences in Beijing. Then he moved to University of Cambridge as post-doctoral research associate to work on nanofabrication in Chemistry Department and Nanoscience Centre. After that he joined Toshiba Research Europe Limited in June 2004, worked as a research scientist in Quantum Communication Group in Cambridge Science Park. From 2008, He started to work with Nokia Research Centre as a Principal Researcher in Quantum Technologies.
