Observation and investigation of narrow optical transitions of 167Er3+ ions in femtosecond laser printed waveguides in 7LiYF4 crystal
M. M. Minnegaliev, I. V. Dyakonov, K. I. Gerasimov +5
We produced optical waveguides in the 167Er3+ :7LiYF4 crystal with diameters ranging from 30 to 100 mkm by using the depressed-cladding approach with femtosecond laser. These waveg…
Multi-photon subtracted thermal states: description, preparation and reconstruction
Yu. I. Bogdanov, K. G. Katamadze, G. V. Avosopyants +4
We present a study of optical quantum states generated by subtraction of photons from the thermal state. Some aspects of their photon number and quadrature distributions are discus…
Quantum polarization transformations in anisotropic dispersive medium
Yu. I. Bogdanov, A. A. Kalinkin, S. P. Kulik +2
Based on the concept of chi-matrix and Choi-Jamiolkowski states we develop the approach of quantum process reconstruction. Special attention is paid to the adequacy of applied reco…
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-…
Angular Schmidt Modes in Spontaneous Parametric Down-Conversion
S. S. Straupe, D. P. Ivanov, A. A. Kalinkin +2
We report a proof-of-principle experiment demonstrating that appropriately chosen set of Hermite-Gaussian modes constitutes a Schmidt decomposition for transverse momentum states o…
