Generalized schmidt decomposition and classification of three-quantum-Bit states
We prove for any pure three-quantum-bit state the existence of local bases which allow one to build a set of five orthogonal product states in terms of which the state can be written in a unique form. This leads to a canonical form which generalizes the two-quantum-bit Schmidt decomposition. It is uniquely characterized by the five entanglement parameters. It leads to a complete classification ...
متن کاملEntanglement of Multipartite Schmidt-correlated States Entanglement of Multipartite Schmidt-correlated States
We generalize the Schmidt-correlated states to multipartite systems. The related equivalence under SLOCC, the separability, entanglement witness, entanglement measures of negativity, concurrence and relative entropy are investigated in detail for the generalized Schmidt-correlated states.
متن کاملQuantum and classical correlations in Bell three and four qubits, related to Hilbert-Schmidt decomposition
The present work studies quantum and classical correlations in 3-qubits and 4-qubits general Bell states, produced by operating with n B Braid operators on the computational basis of states. The analogies between the general 3qubits and 4-qubits Bell states and that of 2-qubits Bell states are discussed. The general Bell states are shown to be maximal entangled, i.e., with quantum correlations ...
متن کاملThe relative entanglement of Schmidt correlated states and distillation
We show that a mixed state ρ = ∑ mn amn|m〉〈n| can be realized by an ensemble of pure states {pk, |φk〉} where |φk〉 = ∑ m √ amme iθ m |m〉. Employing this form, we discuss the relative entanglement of Schmidt correlated states. Also, we calculate the distillable entanglement of a class of mixed states. 03.67.-a,03.65.Bz,03.65.Ud Typeset using REVTEX
متن کاملLocally undetermined states, generalized schmidt decomposition, and application in deistributed comuting
Multipartite quantum states that cannot be uniquely determined by their reduced states of all proper subsets of the parties exhibit some inherit ‘high-order’ correlation. This paper elaborates this issue by giving necessary and sufficient conditions for a pure multipartite state to be locally undetermined, and moreover, characterizing precisely all the pure states sharing the same set of reduce...
