In this paper we provide an analytical procedure for explicit calculation of the left and right invariant vector fields and oneforms on SU(N) manifold. The calculations are based on the coset parametrization of SU(N) group. ...

The aim of this paper is to provide a method for explicit computation of the Bures metric over the space of N-level quantum system, based on the coset parametrization of density matrices.

An explicit parametrization for the state space of an n-level density matrix is given.

The parametrization is based on the canonical coset decomposition of unitary matrices.

We also compute, explicitly, the ...

We study the boson–parafermion entanglement of the parasupersymmetric coherent

states of the harmonic oscillator and derive the degree of entanglement in terms of the

concurrence. The conditions for obtaining ...

We will study entangled two-photon states generated from a two-mode supersymmetric

model and quantify degree of entanglement in terms of the entropy of entanglement.

The influences of the nonlinearity on the ...

For a given pure state of amultipartite system, the concurrence vector is defined

by employing the defining representation of generators of the corresponding

rotation groups. The norm of a concurrence vector ...

In this paper, we use the concurrence vector as a measure of entanglement, and investigate lower and upper bounds on the concurrence of a superposition of bipartite states as a function of the concurrence of the superposed ...
