Fock-state superradiance in a cold atomic ensemble
D. F. Barros, L. F. Muñoz-Martínez, L. Ortiz-Gutiérrez +7
A simplified theory for the wavepackets of the photons emitted during the read process of a quantum memory formed by cold atoms is provided. We arrive at analytical expressions for…
Hexapartite entanglement in an above-threshold Optical Parametric Oscillator
F. A. S. Barbosa, A. S. Coelho, L. F. Muñoz Martínez +4
We demonstrate, theoretically and experimentally, the generation of hexapartite modal entanglement by the optical parametric oscillator (OPO) operating above the oscillation thresh…
Exploring six modes of an optical parametric oscillator
Luis F. Muñoz-Martínez, Felippe Alexandre Silva Barbosa, Antônio Sales Coelho +4
We measure the complete quantum state for six modes of the electromagnetic field produced by an optical parametric oscillator. The investigation involves the sideband of the intens…
