Noisy Qutrit Channels
A. Checinska, K. Wodkiewicz
We present an analysis of spontaneous emission in a 3-level atom as an example of a qutrit state under the action of noisy quantum channels. We choose a 3-level atom with V-configu…
Effective generation of cat and kitten states
Magdalena Stobińska, G. J. Milburn, Krzysztof Wódkiewicz
We present an effective method of coherent state superposition (cat state) generation using single trapped ion in a Paul trap. The method is experimentally feasible for coherent st…
Witnessing Entanglement with Second-Order Interference and Stokes Parameters
Magdalena Stobińska, Krzysztof Wódkiewicz
We propose to use Stokes parameter as an entanglement witness for correlated EPR mixed states of light. Such states can be generated with a beam splitter acting on two mixed squeez…
Time-frequency Domain Analogues of Phase Space Sub-Planck Structures
Ludmila Praxmeyer, Piotr Wasylczyk, Czeslaw Radzewicz +1
We present experimental data of the frequency resolved optical gating (FROG) measurements of light pulses revealing interference features corresponding to sub-Planck structures in…
Witnessing Entanglement of EPR States With Second-Order Interference
Magdalena Stobińska, Krzysztof Wódkiewicz
The separability of the continuous-variable EPR state can be tested with Hanbury-Brown and Twiss type interference. The second-order visibility of such interference can provide an…
Time and Frequency description of Optical Pulses
Ludmila Praxmeyer, Krzysztof Wodkiewicz
The connection between the time-dependent physical spectrum of light and the phase space overlap of Wigner functions is investigated for optical pulses. Time and frequency properti…
