$η$-trigonometric states of four qubits and entanglement measures

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/220964Entanglement of four qubit pure states defined by the $η$-trigonometric functions is studied. We analyze the behavior of two recently proposed symmetric entanglement monotones on the chosen $n=4$ qubit states .7 pages, no figuresQuantum Physics$η$-trigonometric states of four qubits and entanglement measurestext
