Orbital angular momentum from marginals of quadrature distributions
L. L. Sanchez-Soto, A. B. Klimov, P. de la Hoz +4
We set forth a method to analyze the orbital angular momentum of a light field. Instead of using the canonical formalism for the conjugate pair angle-angular momentum, we model thi…
Amplification of realistic cat-like states by homodyne heralding
Amine Laghaout, Jonas S. Neergaard-Nielsen, Ioannes Rigas +3
We present a scheme for the amplification of Schrodinger cats that collapses two smaller states onto their constructive interference via a homodyne projection. We analyze the perfo…
Generation of continuous-variable cluster states of cylindrically polarized modes
I. Rigas, C. Gabriel, S. Berg-Johansen +5
Cluster states are an essential component in one-way quantum computation protocols. We present two schemes to generate addressable continuous-variable cluster states from quadratur…
Orbital angular momentum in phase space
I. Rigas, L. L. Sanchez-Soto, A. B. Klimov +2
A comprehensive theory of the Weyl-Wigner formalism for the canonical pair angle-angular momentum is presented. Special attention is paid to the problems linked to rotational perio…
Nondiffracting beams for vortex tomography
J. Rehacek, Z. Hradil, Z. Bouchal +3
We propose a reconstruction of vortex beams based on the implementation of quadratic transformations in the orbital angular momentum. The information is encoded in a superposition…
A Hybrid Long-Distance Entanglement Distribution Protocol
Jonatan B. Brask, Ioannes Rigas, Eugene S. Polzik +2
We propose a hybrid (continuous-discrete variable) quantum repeater protocol for distribution of entanglement over long distances. Starting from entangled states created by means o…
Full tomography from compatible measurements
J. Rehacek, Z. Hradil, Z. Bouchal +3
We put forward a reconstruction scheme prompted by the relation between a von Neumann measurement and the corresponding informationally complete measurement induced in a relevant r…
Angular performance measure for tighter uncertainty relations
Z. Hradil, J. Rehacek, A. B. Klimov +2
The uncertainty principle places a fundamental limit on the accuracy with which we can measure conjugate physical quantities. However, the fluctuations of these variables can be as…
Non-negative Wigner functions for orbital angular momentum states
I. Rigas, L. L. Sanchez-Soto, A. B. Klimov +2
The Wigner function of a pure continuous-variable quantum state is non-negative if and only if the state is Gaussian. Here we show that for the canonical pair angle and angular mom…
Wigner function for twisted photons
I. Rigas, L. L. Sanchez-Soto, A. B. Klimov +2
A comprehensive theory of the Weyl-Wigner formalism for the canonical pair angle-angular momentum is presented, with special emphasis in the implications of rotational periodicity…
Full quantum reconstruction of vortex states
I. Rigas, L. L. Sanchez-Soto, A. B. Klimov +2
We propose a complete tomographic reconstruction of any vortex state carrying orbital angular momentum. The scheme determines the angular probability distribution of the state at d…
