Deterministic generation of arbitrary symmetric states and entanglement classes
L. Lamata, C. E. Lopez, B. P. Lanyon +3
We propose a method to generate arbitrary symmetric states of N qubits, which can be easily associated with their entanglement classes. It is particularly suited to quantum optics…
Quantum tomography in position and momentum space
J. Casanova, C. E. Lopez, J. J. Garcia-Ripoll +2
We introduce a method of quantum tomography for a continuous variable system in position and momentum space. We consider a single two-level probe interacting with a quantum harmoni…
Sudden Birth Versus Sudden Death of Entanglement in Multipartite Systems
C. E. Lopez, G. Romero, F. Lastra +2
We study the entanglement dynamics of two cavities interacting with independent reservoirs. Expectedly, we observe that, as the cavity entanglement is depleted, it is transferred t…
Entangled coherent states under dissipation
F. Lastra, G. Romero, C. E. Lopez +2
We study the evolution of entangled coherent states of the two quantized electromagnetic fields under dissipation. Characteristic time scales for the decay of the negativity are fo…
Selective Control of the Symmetric Dicke Subspace in Trapped Ions
C. E. Lopez, J. C. Retamal, E. Solano
We propose a method of manipulating selectively the symmetric Dicke subspace in the internal degrees of freedom of N trapped ions. We show that the direct access to ionic-motional…
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…
