Asymmetric double well system as effective model for the kicked one
V. I. Kuvshinov, A. V. Kuzmin, V. A. Piatrou
Effective Hamiltonian for the kicked double well system was derived using the Campbell-Baker-Hausdorff expansion formula. Asymmetric model for the kicked system was constructed. An…
Chaotic instantons and enhancement of tunneling in double-well system with polychromatic perturbation
V. I. Kuvshinov, A. V. Kuzmin, V. A. Piatrou
Chaotic instanton approach allows to describe analytically the influence of the polychromatic perturbation on quantum properties of nonlinear systems. Double well system with singl…
Chaotic instantons and enhancement of tunneling in kicked double-well system with time-reversal symmetry
V. I. Kuvshinov, A. V. Kuzmin, V. A. Piatrou
Chaotic instanton approach is used to describe dynamical tunneling in kicked double well system. Effective Hamiltonian for the kicked system is obtained using matrix expansion form…
Chaotic instantons in periodically perturbed double-well system
V. I. Kuvshinov, A. V. Kuzmin, V. A. Piatrou
Kicked double-well system is investigated both analytically and numerically. Phenomenological formula for ground quasienergy splitting is obtained using resonances overlap criterio…
On connection between purity and fidelity of quantum channels
A. V. Kuzmin
Quantum channels depending on a number of classical control parameters are considered. Assuming the stochastic fluctuations of the control parameters in the small errors limit it i…
Decoherence induced by squeezing control errors in optical and ion trap holonomic quantum computations II
V. I. Kuvshinov, A. V. Kuzmin
We study decoherence induced by stochastic squeezing control errors considering the particular implementation of Hadamard gate on optical and ion trap holonomic quantum computers.…
