Self-calibrating Tomography for Angular Schmidt Modes in Spontaneous Parametric Down-Conversion
Stanislav Straupe, Denis Ivanov, Alexander Kalinkin +3
We report an experimental self-calibrating tomography scheme for entanglement characterization in high-dimensional quantum systems using Schmidt decomposition techniques. The self-…
Non-Markovian effects on non-locality of a qubit-oscillator system
Jie Li, Gerard McKeown, Fernando L. Semiao +1
Non-Markovian evolutions are responsible for a wide variety of physically interesting effects. Here, we study non-locality of the non-classical state of a system consisting of a qu…
Theoretical and experimental aspects of quantum discord and related measures
Lucas C. Céleri, Jonas Maziero, Roberto M. Serra
Correlations are a very important tool in the study of multipartite systems, both for classical and quantum ones. The discussion about the quantum nature of correlations permeates…
Generators of nonclassical states by combination of the linear coupling of boson modes, Kerr nonlinearity and the strong linear losses
V. S. Shchesnovich, D. Mogilevtsev
We show that the generators of quantum states of light can be built by employing the Kerr nonlinearity, a strong linear absorption or losses and the linear coupling of optical mode…
Environment-induced sudden transition in quantum discord dynamics
R. Auccaise, L. C. Celeri, D. O. Soares-Pinto +7
Non-classical correlations play a crucial role in the development of quantum information science. The recent discovery that non-classical correlations can be present even in separa…
Experimentally Witnessing the Quantumness of Correlations
R. Auccaise, J. Maziero, L. C. Celeri +6
The quantification of quantum correlations (other than entanglement) usually entails laboured numerical optimization procedures also demanding quantum state tomographic methods. Th…
