2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/141691We propose a method for generating all symmetric Dicke states, either in the long-lived internal levels of N massive particles or in the polarization degrees of freedom of photonic qubits, using linear optical tools only. By means of a suitable multiphoton detection technique, erasing Welcher-Weg information, our proposed scheme allows the generation and measurement of an important class of entangled multiqubit states.New version, a few modifications and a new figure, accepted in Physical Review LettersQuantum Physicstext
