Stability of holonomic quantum computations
V. I. Kuvshinov, A. V. Kuzmin
We study the stability of holonomic quantum computations with respect to errors in assignment of control parameters. The general expression for fidelity is obtaned. In the small er…
Chaos Enforced Instanton Tunnelling in One-Dimensional Model with Periodic Potential
V. I. Kuvshinov, A. V. Kuzmin, R. G. Shulyakovsky
The influence of chaos on properties of dilute instanton gas in quantum mechanics is studied. We demonstrate on the example of one-dimensional periodic potential that small perturb…
Heading towards chaos criterion for quantum field systems
V. I. Kuvshinov, A. V. Kuzmin
Chaos criterion for quantum field theory is proposed. Its accordance with classical chaos criterion is demonstrated in the semi-classical limit of quantum mechanics.
Bunching Parameter and Intermittency in High-Energy Collisions
S. V. Chekanov, V. I. Kuvshinov
We introduce the parameter of bunching for an analysis of the intermittent structure of multihadron production in high-energy collisions following an analogy with photon counting i…
