The ${\ell }_1$-norm in quantum information via the approach of Yang-Baxter Equation

Kai Niu, Kang Xue, Qing Zhao +1

The role of ${\ell }_1$-norm in Quantum Mechanics (QM) has been studied through Wigner's D-functions where ${\ell }_1$-norm means ${\sum }_i\left|C_i\right|$ for $\left|Ψ\right\rang…
