Non-Orthogonality Measure for a Collection of Pure Quantum States
Entropy, 2022 Modern optical communication technology can realize a large-scale multilevel (or M-ary) optical signal. Investigating the quantum mechanical nature of such a large-scale M-ary optical signal is essential for a unified understanding of quantum information
