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…
Measurement-induced strong Kerr nonlinearity for weak quantum states of light
Luca S. Costanzo, Antonio S. Coelho, Nicola Biagi +3
Strong nonlinearity at the single photon level represents a crucial enabling tool for optical quantum technologies. Here we report on experimental implementation of a strong Kerr n…
