Optimal superposition enhancement of a mixed state by stochastic diagonal superposition-free operations

The resource theory of superposition is a generalization of coherence theory. A rigorous framework for quantifying superposition of linear independent states has been given by previous studies. In this paper, the optimal superposition enhancement of a mixed state is studied. Based on the l1 measure...
