Constant rotation of two-qubit equally entangled pure states by local quantum operations
Samir Kunkri, Swarup Poria, Preeti Parashar +1
We look for local unitary operators which would rotate all equally entangled two-qubit pure states by the same but arbitrary amount. It is shown that all two-qubi…

N-Qubit W States are Determined by their Bipartite Marginals
Preeti Parashar, Swapan Rana
We prove that the most general W class of N-qubit states are uniquely determined among arbitrary states (pure or mixed) by just their bipartite reduced density matrices. Moreover,…
