Visualization of all two-qubit states via partial-transpose-moments
Lin Zhang, Yi Shen, Hua Xiang +2
Efficiently detecting entanglement based on measurable quantities is a basic problem for quantum information processing. Recently, the measurable quantities called partial-transpos…
Randomized Iterative Methods with Alternating Projections
Hua Xiang, Lin Zhang
We use a unified framework to summarize sixteen randomized iterative methods including Kaczmarz method, coordinate descent method, etc. Some new iterative schemes are given as well…
A variant of Horn's problem and derivative principle
Lin Zhang, Hua Xiang
Identifying the spectrum of the sum of two given Hermitian matrices with fixed eigenvalues is the famous Horn's problem.In this note, we investigate a variant of Horn's problem, i.…
Average entropy of a subsystem over a global unitary orbit of a mixed bipartite state
Lin Zhang, Hua Xiang
We investigate the average entropy of a subsystem within a global unitary orbit of a given mixed bipartite state in the finite-dimensional space. Without working out the closed-for…
