Uncertainty and Complementarity Relations in Weak Measurement
Arun Kumar Pati, Junde Wu
We prove uncertainty relations that quantitatively express the impossibility of jointly sharp preparation of pre- and post-selected quantum states for measuring incompatible observ…
The Local Orthogonality between Quantum States and Entanglement Decomposition
Sunho Kim, Junde Wu, Lin Zhang +1
In the paper, we show that when a quantum state can be decomposed as a convex combination of locally orthogonal mixed states, its entanglement can be decomposed into the entangleme…
Conditions for Anomalous Weak Value
Arun Kumar Pati, Junde Wu
We show that the weak value of any observable in pre- and post-selected states can be expressed as the sum of the average of the observable in the pre-selected state and an anomalo…
A lower bound on the fidelity between two states in terms of their trace-distance and max-relative entropy
Lin Zhang, Kaifeng Bu, Junde Wu
Fidelity is a fundamental and ubiquitous concept in quantum information theory. Fuchs-van de Graaf's inequalities deal with bounding fidelity from above and below. In this paper, w…
Interference Visibility as a Witness of Entanglement and Quantum Correlation
Lin Zhang, Arun Kumar Pati, Junde Wu
In quantum information and communication one looks for the non-classical features like interference and quantum correlations to harness the true power of composite systems. We show…
A lower bound of quantum conditional mutual information
Lin Zhang, Junde Wu
In this paper, a lower bound of quantum conditional mutual information is obtained by employing the Peierls-Bogoliubov inequality and Golden Thompson inequality. Comparison with th…
