Entropy fluctuation formulas of fermionic Gaussian states
Youyi Huang, Lu Wei
We study the statistical behaviour of quantum entanglement in bipartite systems over fermionic Gaussian states as measured by von Neumann entropy. The formulas of average von Neuma…

Average capacity of quantum entanglement
Lu Wei
As an alternative to entanglement entropies, the capacity of entanglement becomes a promising candidate to probe and estimate the degree of entanglement of quantum bipartite system…

Antilinear superoperator, quantum geometric invariance, and antilinear symmetry for higher-dimensional quantum systems
Lu Wei, Zhian Jia, Dagomir Kaszlikowski +1
We present a systematic investigation of antilinear superoperators and their applications in studying open quantum systems, particularly focusing on quantum geometric invariance, e…
