Improvement of the deterministic preparation of Dicke states
Keywords:

An improved scheme for the deterministic creation of quantum Dicke states without the use of ancilla qubits is constructed in the paper. A slight weakening of Linear Nearest Neighbor topology made it possible to reduce the number of used gates from O(nk) to O(n) for the Dicke state |Dkn>.
