Direct measurement of concurrence for atomic two-qubit pure states
G. Romero, C. E. Lopez, F. Lastra +2
We propose a general scheme to measure the concurrence of an arbitrary two-qubit pure state in atomic systems. The protocol is based on one- and two-qubit operations acting on two…

Effective Quantum Dynamics of Interacting Systems with Inhomogeneous Coupling
C. E. Lopez, H. Christ, J. C. Retamal +1
We study the quantum dynamics of a single mode/particle interacting inhomogeneously with a large number of particles and introduce an effective approach to find the accessible Hilb…
