چکیده

We study the problem of converting a product of Greenberger-HorneZeilinger (GHZ) states shared by subsets of several parties in an arbitrary way into GHZ states shared by every party. Our result is that if SLOCC transformations are allowed, then the best asymptotic rate is the minimum of bipartite log-ranks of the initial state. This generalizes a result by Strassen on the asymptotic subrank of the matrix multiplication tensor.

Entanglement classification of relaxed Greenberger-Horne-Zeilinger symmetric states

In this paper we analyze entanglement classification of relaxed Greenberger-HorneZeilinger-symmetric states ρES , which is parametrized by four real parameters x, y1, y2 and y3. The condition for separable states of ρES is analytically derived. The higher classes such as bi-separable, W, and Greenberger-Horne-Zeilinger classes are roughly classified by making use of the class-specific optimal w...

Multiparticle Interference , Greenberger - Horne - Zeilinger Entanglement , and Full Counting Statistics SIM , H . - S . , SUKHORUKOV , Eugene

We investigate the quantum transport in a generalized N-particle Hanbury Brown–Twiss setup enclosing magnetic flux, and demonstrate that the Nth-order cumulant of current cross correlations exhibits Aharonov-Bohm oscillations, while there is no such oscillation in all the lower-order cumulants. The multiparticle interference results from the orbital Greenberger-Horne-Zeilinger entanglement of N...

Necessary and sufficient condition for Greenberger-Horne-Zeilinger diagonal states to be full N-partite entanglement

We show that any N -qubit state which is diagonal in the Greenberger-HorneZeilinger basis is full N -qubit entangled state if and only if no partial transpose of the multiqubit state is positive with respect to any partition.

N-tangle of the Superposition of Greenberger-Horne- Zeilinger States

In the paper, use the n-tangle, as a measure of entanglement to investigate the superposition of Greenberger-Horne-Zeilinger states for even n qubits. The paper show that orthogonal basis with the GHZ state can be divided into two group via SLOCC –invariant. In the same group, an expression for any two superposed state is provided, when the superposition coefficient is real, the n-tangle of sup...
