Two-level quantum dynamics, integrability and unitary NOT gates
Renato M. Angelo, Walter F. Wreszinski
We study the dynamics of a two-level quantum system interacting with an external electromagnetic field periodic and quasiperiodic in time. The quantum evolution is described exactl…

Correspondence principle for the diffusive dynamics of a quartic oscillator: deterministic aspects and the role of temperature
Renato M. Angelo
The correspondence principle is investigated in the framework of deterministic predictions for individual systems. Exact analytical results are obtained for the quantum and the Lio…

Quantum NOT Operation and Integrability in Two-Level Systems
Renato M. Angelo, Walter F. Wreszinski
We demonstrate the surprising integrability of the classical Hamiltonian associated to a spin 1/2 system under periodic external fields. The one-qubit rotations generated by the dy…
