Phase space formulation of density operator for non-Hermitian Hamiltonians and its application in quantum theory of decay
Ludmila Praxmeyer, Konstantin G. Zloshchastiev
The Wigner-Weyl transform and phase space formulation of a density matrix approach are applied to a non-Hermitian model which is quadratic in positions and momenta. We show that in…
Phase space representation of non-Hermitian system with -symmetry
Ludmila Praxmeyer, Popo Yang, Ray-Kuang Lee
We present a phase space study of non-Hermitian Hamiltonian with -symmetry based on the Wigner distribution function. For an arbitrary complex potential, we derive a…
Families of Orthogonal Schrodinger cat-like-states
Ludmila Praxmeyer
We analyze condition of orthogonality between optical Schrodinger cat-like-states constructed as superposition of two coherent states. We show that the orthogonality condition lead…
Direct Measurement of Time-Frequency Analogues of Sub-Planck Structures
Ludmila Praxmeyer, Chih-Cheng Chen, Popo Yang +2
Exploiting the correspondence between Wigner distribution function and a frequency-resolved optical gating (FROG) measurement, we experimentally demonstrate existence of the chessb…
Reposition time in probabilistic imperfect memories
Ludmiła Praxmeyer
We present the analysis of behavior of N identical finite time memories with the imperfections characterized by a step-function model, based on a study of independent copies of the…
Rate analysis for a hybrid quantum repeater
Nadja K. Bernardes, Ludmiła Praxmeyer, Peter van Loock
We present a detailed rate analysis for a hybrid quantum repeater assuming perfect memories and using optimal probabilistic entanglement generation and deterministic swapping routi…
