Comparing Energy Difference and Fidelity of Quantum States
Victor V. Dodonov
We look for upper bounds of the relative energy difference of two pure quantum states with a fixed fidelity between them or upper bounds of the fidelity for a fixed relative energy…
Upper bounds on the relative energy difference of pure and mixed Gaussian states with a fixed fidelity
V. V. Dodonov
Exact and approximate formulas for the upper bound of the relative energy difference of two Gaussian states with the fixed fidelity between them are derived. The reciprocal formula…
Approximate analytical results on the cavity dynamical Casimir effect in the presence of a two-level atom
A. V. Dodonov, V. V. Dodonov
We study analytically the photon generation from vacuum due to the Dynamical Casimir effect in a cavity with a two-level atom, prepared initially in an arbitrary pure state. Perfor…
Quantum information transfer in degenerate Raman regime
Thiago Prudencio
The interaction of a three level Rydberg atom of Lambda-type with a single mode optical field in far off-resonant and at large detuning regimes can be described by an effective deg…
No-cloning theorem in thermofield dynamics
Thiago Prudencio
We discuss the relation between the no-cloning theorem from quantum information and the doubling procedure used in the formalism of thermofield dynamics (TFD). We also discuss how…
