Quantum State Tomography in a Third-Order Integrated Optical Parametric Oscillator
Roger Alfredo Kögler, Gabriel Couto Rickli, Renato Ribeiro Domeneguetti +5
We measured the covariance matrix of the fields generated in an integrated third-order optical parametric oscillator operating above threshold. We observed up to dB…
Continuous Variable Entanglement in an Optical Parametric Oscillator Based on a Nondegenerate Four Wave Mixing Process in Hot Alkali Atoms
A. Montaña Guerrero, R. L. Rincón Celis, P. Nussenzveig +3
We present the measurement of entanglement between twin beams generated with a doubly resonant optical parameter oscillator (OPO) based on four-wave mixing in hot Rb vapor a…
Quantum noise correlations of an optical parametric oscillator based on a non-degenerate four wave mixing process in hot alkali atoms
A. Montaña Guerrero, P. Nussenzveig, M. Martinelli +2
We present the first measurement of two-mode squeezing between the twin beams produced by a doubly resonant optical parameter oscillator (OPO) in above threshold operation, based o…
Are all Gaussian states also cluster states? Essential diagnostic tools for continuous-variable one-way quantum computing
Carlos González-Arciniegas, Paulo Nussenzveig, Marcelo Martinelli +1
Continuous-variable (CV) cluster states are a universal quantum computing platform that has experimentally out-scaled qubit platforms by orders of magnitude. Room-temperature imple…
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…
