Quantum Optics for Quantum Information

This research is led by Prof. Antonio Zelaquett Khoury and Prof. Kaled Dechoum.

Quantum and classical correlations in optical parametric amplifiers (OPO's)

  • Study of bipartite, tripartite and multimode correlations among transverse modes.


Recent papers:

Semiclassical Wigner distribution for a two-mode entangled state generated by an OPO. Dechoum, Hahn, Vallejos, Khoury; PRA 81, 043834 (2010)
Entanglement criteria and classical correlations in parametric amplifiers. da Silva, Khoury, Dechoum; PRA 78, 025803 (2008).

Manipulating different degrees of freedom for quantum information

  • Entanglement between polarization and orbital angular momentum
  • Hyperentanglement between these degrees of freedom in the OPO

Recent papers:

A Michelson controlled-not gate with a single-lens astigmatic mode converter. Souza, Khoury, Optics Express18, 9207 (2010).
Continuous-Variable Hyperentanglement in a Parametric Oscillator with Orbital Angular Momentum. dos Santos, Dechoum, Khoury; Phys. Rev. Lett. 103, 230503 (2009).   

Geometrical phases in quantum systems

  • Dynamics of OPO spatial modes with injection of angular momentum.
  • Topological phases.
