Quantum computation: a brief introduction and discussion on recent trends
Wednesday, 9 August 2023, 2:00-3:00 p.m. (Taipei time)
Q&A 3:00-3:30 p.m.
Venue:
Education and Research Building 教學研究大樓 S101 (Gongguan Campus)
Speaker:
Prof. Tzu-Chieh Wei 魏子傑 (C.N. Yang Institute for Theoretical Physics, State University of New York at Stony Brook)
Abstract:
Quantum computation is a novel way of information processing that allows, for certain classes of problems, exponential speedup over classical computation. In addition to the standard circuit picture, various models of quantum computation exist, such as the adiabatic, circuit, and measurement-based models, and they operate very differently and may suit different physical realizations. I will give a pedagogical introduction to quantum computation so as to give some idea why quantum computers seem powerful and yet it is not easy to design quantum algorithms that outperform classical ones. Quantum computers can be used to simulate other quantum systems, and this potentially opens up many potential applications of quantum computers, including quantum many-body problems and quantum chemistry, in addition to other quantum algorithmic pursuits. I will also discuss the opportunities that cloud-based quantum computers offer. This is an exciting era where many quantum information and quantum computing tasks can be at least tested and technological applications may soon arrive.
