Heisenberg Uncertainty Relation for Coarse-grained Observables
Lukasz Rudnicki, Stephen P. Walborn, Fabricio Toscano
We ask which is the best strategy to reveal uncertainty relations between comple- mentary observables of a continuous variable system for coarse-grained measurements. This leads to…
Decoherence, entanglement decay, and equilibration produced by chaotic environments
Gabriela Barreto Lemos, Fabricio Toscano
We investigate decoherence in quantum systems coupled via dephasing-type interactions to an arbitrary environment with chaotic underlying classical dynamics. The coherences of the…
Continuous variable quantum computation with spatial degrees of freedom of photons
D. S. Tasca, R. M. Gomes, F. Toscano +2
We discuss the use of the transverse spatial degrees of freedom of photons propagating in the paraxial approximation for continuous variable information processing. Given the wide…
Production of optical phase space vortices with non-locally distributed mode converters
R. M. Gomes, A. Salles, F. Toscano +2
Optical vortices have been observed in a wide variety of optical systems. They can be observed directly in the wavefront of optical beams, or in the correlations between pairs of e…
