Spontaneous parametric down-conversion pumped by spatiotemporal structured light
Lukas Montenegro, Rafael F. Barros
Here we investigate the all-optical control of spectral correlations in spontaneous parametric down-conversion. We show that when photon pairs are projected onto high-order spatial…

Controlling quantum entanglement with classical non-separable light
R. F. Barros, A. L. S. Santos Junior, A. Z. Khoury +1
Here we investigate the quantum frequency conversion of entangled photons driven by a classically non-separable laser beam. We show that the frequency conversion dynamics is descri…

Quantum-controlled cluster states
R. F. Barros, G. B. Alves, O. Pfister +1
Quantum optical cluster states have been increasingly explored, in the light of their importance for measurement-based quantum computing. Here we set forth a new method for generat…
