Experimental Adaptive Quantum Tomography of Two-Qubit States
Gleb Struchalin, Ivan Pogorelov, Stanislav Straupe +3
We report an experimental realization of adaptive Bayesian quantum state tomography for two-qubit states. Our implementation is based on the adaptive experimental design strategy p…
Quantum Correlations and Superluminal Interaction
Alexander V. Belinsky, Michael H. Shulman
The paper attempts to solve the well known conflict between Relativity and Quantum Mechanics. Accordingly to our concept the instant correlations between the EPR-partners can be ex…
Experimental Demonstration of Negative-Valued Polarization Quasi-Probability Distribution
K. Yu. Spasibko, M. V. Chekhova, F. Ya. Khalili
Polarization quasiprobability distribution defined in the Stokes space shares many important properties with the Wigner function for the position and momentum. Most notably, they b…
Three-photon generation by means of third-order spontaneous parametric down-conversion in bulk crystals
N. A. Borshchevskaya, K. G. Katamadze, S. P. Kulik +1
We investigate the third order spontaneous parametric down-conversion process in a nonlinear media with inversion centers. Specifically, we analyze in details the three-photon diff…
Minimalist design of a robust real-time quantum random number generator
K. S. Kravtsov, I. V. Radchenko, S. P. Kulik +1
We present a simple and robust construction of a real-time quantum random number generator (QRNG). Our minimalist approach ensures stable operation of the device as well as its sim…
Quantum system with a shock wave
Evgeny Perepelkin, Boris Sadovnikov, Natalia Inozemtseva
The experimental shock wave, discovery in quantum systems is the important one through last years. This effect has several phenomenological explanations. It seems to us there is in…
