Entanglement, mixedness, and spin-flip symmetry in multiple-qubit systems
نویسندگان
چکیده
A relationship between a recently introduced multipartite entanglement measure, state mixedness, and spinflip symmetry is established for any finite number of qubits. It is also shown that, for those classes of states invariant under the spin-flip transformation, there is a complementarity relation between multipartite entanglement and mixedness. A number of example classes of multiple-qubit systems are studied in light of this relationship.

Thermal effect and role of entanglement and coherence on excitation transfer in a spin chain
We analyze the role of bath temperature, coherence and entanglement on excitation transfer in a spin chain induced by the environment. In Markovian regime, we show that coherence and entanglement are very sensitive to bath temperature and vanish in time in contrary to the case of having zero-temperature bath. That is while, finding the last qubit of the chain in excited state increases by incre...

متن کاملAnalytical results for entanglement in the five-qubit anisotropic Heisenberg model
We solve the eigenvalue problem of the five-qubit anisotropic Heisenberg model, without use of Bethe’s ansatz, and give analytical results for entanglement and mixedness of two nearest-neighbor qubits. The entanglement takes its maximum at ∆= 1 (∆> 1) for the case of zero (finite) temperature with ∆ being the anisotropic parameter. In contrast, the mixedness takes its minimum at ∆= 1 (∆> 1) for...
متن کاملEntanglement in the XZ spin chain model in the external magnetic field
The entanglement at zero-temperature is studied in a two-qubit XZ spin-1/2 chain model in anexternal magnetic field which is applied in the z direction. We have obtained an analytical relation forthe effect of the external magnetic field on the concurrence. It is shown that the ground state of thesystem depends on the strength of exchange coupling. We have shown that the analytical relation oft...
متن کاملTime reversal and n-qubit canonical decompositions
On pure states of n quantum bits, the concurrence entanglement monotone returns the norm of the inner product of a pure state with its spin-flip. The monotone vanishes for n odd, but for n even there is an explicit formula for its value on mixed states, i.e., a closed-form expression computes the minimum over all ensemble decompositions of a given density. For n even a matrix decomposition n=k1...
