报告内容
We determine whether a fixed-spectrum unitary orbit contains a universal source, namely, a state that can be deterministically converted by incoherent operations into every state on the orbit. For qubits, every spectrum admits universal sources, which are exactly the states with equal diagonal entries in the incoherent basis. In dimensions d >2, a universal source exists if and only if the sources are the maximally coherent pure states and the maximally mixed state.
