The best approximation of a given qubit state with the limited pure-state set
Li-qiang Zhang, Deng-hui Yu, Chang-shui Yu
The preparation of quantum states lies at the foundation in the quantum information processing. The convex mixing of some existing quantum states is one of the effective candidate.…
The optimal approximation of qubit states with limited quantum states
Li-qiang Zhang, Deng-hui Yu, Chang-shui Yu
Measuring the closest distance between two states is an alternative and significant approach in the resource quantification, which is the core task in the resource theory. Quite li…
Quantifying coherence in terms of the pure-state coherence
Deng-hui Yu, Li-qiang Zhang, Chang-shui Yu
Quantifying quantum coherence is a key task in the resource theory of coherence. Here we establish a good coherence monotone in terms of a state conversion process, which automatic…
