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…

Hidden entanglement in twin beams generated through optical parametric amplification in hot alkali atoms
R. L. Rincón Celis, G. Nirala, A. Montaña Guerrero +4
Proper characterization of quantum correlations in a multimode optical state is critical for applications in quantum information science; however, the most common entanglement meas…
