ITR: Quantum Entanglement, Information and Computation

这个项目包括对多光子纠缠态及其在量子信息和量子计算中的基础作用的一系列实验和理论研究。目前正在进行的主要工作包括对N光子(N_2纠缠态)以及量子信息和量子计算理论中的“部分纠缠”的实验和理论研究。混合态纠缠的理论表征是这个项目的核心。实验研究主要集中在两个项目上。第一个问题是三光子纠缠态的源的实现。这可能导致实验上产生GHz态。第二个实验项目是在改进Bell态检测实现的基础上进行量子隐形传态。

EIA-0113137Yanhua ShihUniversity of Maryland Baltimore CountyTitle: ITR: Quantum Entanglement, Information and Computation This project consists of a series of experimental and theoretical investigations on multi-photon entangled states and their fundamental role in quantum information and quantum computing. Major efforts underway include experimental and theoretical investigations on N-photon (N2 entangled states) and on "partial entanglement" in quantum information and quantum computation theory. Theoretical characterization of entanglement in mixed states is at the core of this project. The experimental investigations focus on two projects. The first one is the realization of source of three-photon entangled states. These may lead to experimental generation of GHz states. The second experimental project is quantum teleportation based on the improvement on the realization of Bell-state detection.
