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…
Demi-linear Analysis II -- Demi-distributions
Ronglu Li, Shuhui Zhong, Dohan Kim +1
In this paper, we establish a demi-distributions theory which develops the usual distribution theory, in particular, we show that many conclusions as differentiations, Fourier tran…
Demi-linear Analysis III -- Demi-distributions with Compact Support
Ronglu Li, Shuhui Zhong, Dohan Kim +1
A series of detailed quantitative results is established for the family of demi-distributions which is a large extension of the family of usual distributions.
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…
