Chon-Fai Kam received his Ph.D. degree in theoretical condensed matter physics from the Chinese University of Hong Kong in 2018. From 2019 to 2021, he was a Postdoc Fellow at the Department of Mathematics of University of Macau. Since 2022, he has been a Postdoc Fellow at the Department of Physics of University at Buffalo. His research interests include squeezed coherent states, multipartite entanglement, quantum information, quantum phase transition, non-Hermitian systems, and non-adiabatic transitions. He developed a nonlinear quantum mechanics approach to interacting quantum systems, a quantum information approach to quantum phase transitions, and the Majorana star representation for general multipartite entangled states. He is now working on enhanced spin qubit readout using optical squeezed states.


Wei-Min Zhang is a Distinguished Professor of the Physics Department at National Cheng Kung University (NCKU) in Taiwan. He received his PhD intheoretical physics from Drexel University, USA, in 1989. He was Post-Doctoral Research Fellows at the University of Washington in Seattle (1990-1991), and at the Ohio-State University (1992-1993). From 1994 to 1998, he was a Visiting Associate Professor at the Institute of Physics of Academic Sinica at Taipei and became a Full Professor in 1999 and, then, a Distinguished Professor in 2004 at NCKU. His research interests cover many different fields in theoretical physics, including quantum information and quantum computing, mesoscopic physics, quantum optics, open quantum systems and quantum decoherence, quantum transport, strongly correlated many-body physics, quantum chromodynamics (QCD), quantum field theory, quantum chaos, nuclear physics, quantum phase transitions and quantum thermodynamics. He developed the transport theory for heavy-ion collisions, the two component theory of light-front QCD, a SU(2)xU(1) gauge theory for high-temperature superconductivity, the fermionic decoherent theory of nanoelectronics,
