non-Gaussian state generation for light using a trapped ion
Magdalena Stobińska, G. J. Milburn, Krzysztof Wódkiewicz
According to the Gottesmann-Knill theorem the non-Gaussian states are necessary component for a nontrivial quantum computation. We show two efficient and deterministic methods of $…
Separability of entangled qutrits in noisy channels
Agata Chȩcińska, Krzysztof Wódkiewicz
We present an analysis of noisy atomic channels involving qutrits. We choose a three-level atom with V-configuration to be the qutrit state. Gell-Mann matrices and a generalized Bl…
Wigner Function Evolution of Quantum States in Presence of Self-Kerr Interaction
Magdalena Stobińska, G. J. Milburn, Krzysztof Wódkiewicz
A Fokker-Planck equation for the Wigner function evolution in a noisy Kerr medium ( non-linearity) is presented. We numerically solved this equation taking a coherent stat…
Witnessing Entanglement with Second-Order Interference
Magdalena Stobińska, Krzysztof Wódkiewicz
Second-order interference and Hanbury-Brown and Twiss type experiments can provide an operational framework for the construction of witness operators that can test classical and no…
Tutorial Notes on One-Party and Two-Party Gaussian States
Berthold-Georg Englert, Krzysztof Wódkiewicz
Gaussian states -- or, more generally, Gaussian operators -- play an important role in Quantum Optics and Quantum Information Science, both in discussions about conceptual issues a…
