Man Hong Yung, in 2002 and 2004, he received a bachelor’s degree of Physics and a master ‘s degree of Physics from the Chinese University of Hong Kong. In the summer of 2003, he went to Caltech to study the basics of quantum information theory. In 2004, he was invited to the Department of Materials of Oxford University in the UK to participate in the research project of quantum information. Afterwards, he went to UIUC for further study in physics, his advisor was Prof. Anthony Leggett who won the Nobel prize, and conducting interdisciplinary research involving physics and information science. After graduated, he was conducting Postdoctoral research on quantum information and physical chemistry for three years in Harvard University. In September 2013, he returned to China, and he became an assistant professor at the Institute of Interdisciplinary Information at Tsinghua University. In January 2016, he worked as an Associate Professor of Physics at SUSTech. Yung ’s academic work mainly focused on the design of quantum algorithms and

Time-optimal Control of independent Spin-1/2 Systems under Simultaneous Control

Abstract: Show Abstract

We derive the explicit solution of the problem of time-optimal control (TOC) by a common magnetic fields for two independent spin-1/2 particles. Our approach is based on the Pontryagin Maximum Princple (PMP) and a novel symmetry reduction technique. We experimentally implement the optimal control via a home-built zero and ultralow filed NMR spectrometer. This is the first analytical solution and experimental demonstration of time-optimal control in such a system and it provides a route to achieve time optimal control in more general quantum systems.
Narrow-band source of polarization-entangled photons with counterpropagating domain engineering

Abstract: Show Abstract
|, , ,
Photonic entanglement is central resource to quantum information sciences, such as quantum communication and quantum computation. The entangled photons generated in conventional spontaneous parametric down-conversion usually yield THz bandwidth which becomes very dim in many applications call for narrow-band entanglement sources. Here we demonstrate the polarization-entanglement photon source with counterpropagating phase matching, which results in an inherent bandwidth of 7.1 GHz at telecom wavelength. The entanglement is measured to violate the Bell inequality by up to 18.5 standard deviations, with Clauser–Horne–Shimony–Holt S-parameter of 2.720±0.039. The quantum state tomography further characterizes the entanglement, with fidelity F=(95.71±0.61)%.
A. Quantum Computation and Quantum Simulation
This is the first conference focusing on Quantum Engineering in Singapore. The conference generically covers three broad areas of quantum cryptography, quantum computation and quantum metrology and sensing.
