| Abstract: |
We derive that sufficient and necessary conditions for existence of a quantum channel ϕ and a generalized unitary operation ɛ sending A to B (1 ⩾ i ⩾ k) for two given families { A}, { B} of matrices, respectively. As an application, a sufficient and necessary condition for existence of a unitary duality quantum computer with given input-output states is obtained. [ABSTRACT FROM AUTHOR] |
