Hi group, Yudong Cao will be visiting our group on Tuesday 26th (next week). He is a postdoc candidate with research interests in Quantum Computing, Quantum Complexity and Machine Learning. There are still a couple of available slots in the morning. If anyone is interested in meeting with Yudong, please let me know. Yudong will be also giving a talk at the group meeting (*Tuesday 26th 3.30pm in the Division Room*). Please find the title and abstract below. Title: Quantum algorithms and quantum complexity for quantum chemistry Abstract: Recent advances in quantum algorithms and quantum complexity theory could bring new possibilities in applications. Of particular interest is the quantum algorithm for solving linear systems of equations proposed by Harrow, Hassidim and Lloyd. I will talk about my past work with theorists and experimentalists on practical issues of realizing the algorithm, as well as some potential applications for quantum chemistry. On the quantum complexity end, my work is inspired by the observation that some of the tools developed by complexity theorists could be significantly improved and applied on practical adiabatic simulation of many-body quantum systems. I will present some results along this line of inquiry and also how it could be useful for quantum chemistry. Best, Borja
