Quantum computation and analysis of Wigner and Husimi functions: toward a quantum image treatment
M. Terraneo, B. Georgeot, D. L. Shepelyansky
We study the efficiency of quantum algorithms which aim at obtaining phase space distribution functions of quantum systems. Wigner and Husimi functions are considered. Different qu…
Mesoscopic "Rydberg" atom in a microwave field
Tomaz Prosen, Dima Shepelyansky
We establish analogy between a microwave ionization of Rydberg atoms and a charge transport through a chaotic quantum dot induced by a monochromatic field in a regime with a potent…
Nonequilibrium stationary states with ratchet effect
G. Cristadoro, D. L. Shepelyansky
An ensemble of particles in thermal equilibrium at temperature , modeled by Nosè-Hoover dynamics, moves on a triangular lattice of oriented semi-disk elastic scatterers. Despite…
Effects of decoherence and imperfections for quantum algorithms
A. A. Pomeransky, O. V. Zhirov, D. L. Shepelyansky
We study effects of static inter-qubit interactions and random errors in quantum gates on the stability of various quantum algorithms including the Grover quantum search algorithm…
Quantum ratchets in dissipative chaotic systems
Gabriel G. Carlo, Giuliano Benenti, Giulio Casati +1
Using the method of quantum trajectories we study a quantum chaotic dissipative ratchet appearing for particles in a pulsed asymmetric potential in the presence of a dissipative en…
Phase diagram for the Grover algorithm with static imperfections
A. A. Pomeransky, O. V. Zhirov, D. L. Shepelyansky
We study effects of static inter-qubit interactions on the stability of the Grover quantum search algorithm. Our numerical and analytical results show existence of regular and chao…
