Deleterious effect of photon-phonon coupling on microcavities in their application as quantum sources
Y. Sacha C. L. S., G. C. Rickli, J. Dipold +4
In quantum systems, the contact with the environment is detrimental to the purity of the state, thus limiting the practical use of entangled sources in quantum information applicat…
Continuous variable entanglement in a cold-atoms mirrorless optical parametric oscillator
G. C. Borba, R. S. N. Moreira, L. S. Cruz +3
In this work, we explore both the internal and external atomic degrees of freedom to observe quantum entanglement between the modes produced by a mirrorless optical parametric osci…
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…
Role of seeding in the generation of polarization squeezed light by atomic Kerr medium
Eduardo C. Lima, Breno Marques, Marcelo Martinelli +1
Quantum state production and characterization are fundamental elements for many quantum technological applications. In this work, we studied the generation of polarization quantum…
