Quantum-state texture measure and texture transformation
Yufan Lin, Yu Guo, Fei He +1
Quantum-state texture quantifies structural irregularities of a state in a selected basis and has emerged as a valuable resource for gate characterization in universal circuits. Co…
Measure of set imaginarity
Yu Guo, Jiabo Pan, Yuqin Wang +1
Recent studies have shown that Bargmann invariants provide effective detectors of set imaginarity. In this paper, we investigate set imaginarity as a quantum resource in qubit syst…
Conditions for coherence transformations under incoherent operations
Shuanping Du, Zhaofang Bai, Yu Guo
We build the counterpart of the celebrated Nielsen's theorem for coherence manipulation in this paper. This offers an affirmative answer to the open question: whether, given two st…
When quantum channel preserves product states
Yu Guo, Zhaofang Bai, Shuanping Du +1
Product states are always considered as the states that don't contain quantum correlation. We discuss here when a quantum channel sends the product states to themselves. The exact…
The automatic additivity of Lie derivations on von Neumann algebras
Zhaofang Bai, Shuanping Du, Yu Guo
Let be a von Neumann algebra with no central summands of type I. It is shown that every nonlinear Lie derivation () on is an additive d…
Local channels preserving maximal entanglement or Schmidt number
Yu Guo, Zhaofang Bai, Shuanping Du
Maximal entanglement and Schmidt number play an important role in various quantum information tasks. In this paper, it is shown that a local channel preserves maximal entanglement…
