Cohering power of quantum operations
Kaifeng Bu, Asutosh Kumar, Lin Zhang +1
Quantum coherence is a basic feature of quantum physics. Combined with tensor product structure of state space, it gives rise to the novel concepts such as entanglement and quantum…

Fidelity between a bipartite state and another one undergoing local unitary dynamics
Lin Zhang, Lin Chen, Kaifeng Bu
The fidelity and local unitary transformation are two widely useful notions in quantum physics. We study two constrained optimization problems in terms of the maximal and minimal f…
