Abstract
Quantum computing is promising to provide computation advantage over classical
computation in some aspects. It is essential to characterize the system to utilize the
full power of quantum computers since we cannot see the quantum state directly and
it can be fragile to noise. Depending on the performed measurement, we can
reconstruct the state through quantum state tomography or classical shadow
tomography. This can not only characterize the state but can also do error mitigation
through appropriate post-processing in certain circumstances. In this talk, I will discuss
tomography and classical shadow tomography in more detail regarding these aspects.
 
Biography
Ming-Chien Hsu got his Ph.D. degree from Physics Department of National Taiwan
University. After that he moved to National University of Singapore and National Sun
Sat-Yen University with research focusing on condensed matter theory and topological
materials. In 2020 he joined Hon-Hai Research Institute, where he developed research
interests including quantum information, quantum tomography, state learning and
applications of quantum computation in simulating condensed matter systems.
