Wire GEM detector
B. M. Ovchinnikov, V. I. Razin, A. I. Reshetin +1
A wire GEM (WGEM) detector with a gas gap between meshes was constructed. The detector provides the amplification 5x10E5 for the gas mixture of Ar +20% CO2 at atmospheric pressure.…
RETGEM with polyvinylchloride (PVC) electrodes
V. I. Razin, B. M. Ovchinnikov, A. I. Reshetin +1
This paper presents a new design of the RETGEM (Resistive Electrode Thick GEM) based on electrodes made of a polyvinylchloride material (PVC). Our device can operate with gains of…
Distances between quantum states in the tomographic-probability representation
S. N. Filippov, V. I. Man'ko
Distances between quantum states are reviewed within the framework of the tomographic-probability representation. Tomographic approach is based on observed probabilities and is str…
Probability representation and quantumness tests for qudits and two-mode light states
S. N. Filippov, V. I. Man'ko
Using tomographic-probability representation of spin states, quantum behavior of qudits is examined. For a general j-qudit state we propose an explicit formula of quantumness witne…
Chebyshev polynomials and Fourier transform of SU(2) irreducible representation character as spin-tomographic star-product kernel
S. N. Filippov, V. I. Man'ko
Spin-tomographic symbols of qudit states and spin observables are studied. Spin observables are associated with the functions on a manifold whose points are labelled by spin projec…
Spin tomography and star-product kernel for qubits and qutrits
S. N. Filippov, V. I. Man'ko
Using the irreducible tensor-operator technique, we establish the relation between different forms of spin tomograms. Quantizer and dequantizer operators are presented in simple ex…
Quantumness tests and witnesses in the tomographic-probability representation
S. N. Filippov, V. I. Man'ko
In view of the tomographic-probability representation of quantum states, we reconsider the approach to quantumness tests of a single system developed in [Alicki and Van Ryn 2008 J.…
Qubit portrait of the photon-number tomogram and separability of two-mode light states
S. N. Filippov, V. I. Man'ko
In view of the photon-number tomograms of two-mode light states, using the qubit-portrait method for studying the probability distributions with infinite outputs, the separability…
