Abstract
The advantages of the photons makes optical quantum system ideally suited for fundamental quantum physics experiments and a variety of applications in quantum information processing. Here I will briefly review privacy-preserving photonic quantum cloud computing, where quantum information is securely communicated and computed. Related to this I will discuss new experimental insights into the verification of quantum computer and quantum simulators. Based on the utilization of integrated waveguides I will also present new results on resource-efficient intermediate quantum computing utilizing the Bosonic nature of photons as well as new quantum computational concepts that superimpose the order of quantum gates.
As outlook I will briefly discuss the current status of bright multi-photon sources, laser-written waveguide structures and efficient superconducting nanowire detectors, together with the newest results of current experiments.
Bio
Philip Walther is a tenured Associate Professor at the Faculty of Physics at the University of Vienna. Since 2013, he has been the Head of the Quantum Optics, -Nanophysics, -Information Group, which includes seven workgroups with more than 100 people, and in 2014 he also became the Vice-Dean of the Faculty of Physics. He was elected to membership of the German Young Academy in 2007, the Global Young Academy in 2012, and the Junge Kurie at the Austrian Academy of Sciences in 2014. At present, Walther serves as an Associate Editor of the journal Quantum Information from the Nature Publishing Group. After Walther earned his M.Sc in Chemistry from the Vienna University of Technology in 2002, he switched to Physics, obtaining his PhD from the University of Vienna in 2005. After working as a postdoctoral research at Harvard University from 2005 to 2008, he started an independent research group at the University of Vienna, where he became an Assistant Professor in 2011, and was promoted to a tenured Associate Professor in 2013.
Philip Walther's research focuses on photonic quantum information experiments, with an emphasis on photonic quantum computing and quantum simulation. He is especially well known for his pioneering work on photonic quantum simulations, secure quantum computing, and resource-efficient intermediate quantum computing using integrated optical networks.
Walther has contributed to five book chapters, and published more than 50 journal articles. His numerous awards include the Loschmidt Prize (2005), the Fresnel Prize (2011), the Austrian START Prize (2011), the Vienna Funding Award in Science (2011), and the Recognition Award for Science by the Lower State of Austria (2014).
