Experimental investigation of the dynamics of entanglement: Sudden death, complementarity, and continuous monitoring of the environment
A. Salles, F. Melo, M. P. Almeida +4
We report on an experimental investigation of the dynamics of entanglement between a single qubit and its environment, as well as for pairs of qubits interacting independently with…
Quantum key distribution with higher-order alphabets using spatially-encoded qudits
S. P. Walborn, D. S. Lemelle, M. P. Almeida +1
We propose and demonstrate a quantum key distribution scheme in higher-order -dimensional alphabets using spatial degrees of freedom of photons. Our implementation allows for th…
Theoretical investigation of moiré patterns in quantum images
M. P. Almeida, P. H. Souto Ribeiro, J. A. O. Huguenin +1
Moiré patterns are produced when two periodic structures with different spatial frequencies are superposed. The transmission of the resulting structure gives rise to spatial beatin…
Experimental investigation of quantum key distribution with position and momentum of photon pairs
M. P. Almeida, S. P. Walborn, P. H. Souto Ribeiro
We investigate the utility of Einstein-Podolsky-Rosen correlations of the position and momentum of photon pairs from parametric down-conversion in the implementation of a secure qu…
Heat Transport through Rough Channels
J. S. Andrade, E. A. Henrique, M. P. Almeida +1
We investigate the two-dimensional transport of heat through viscous flow between two parallel rough interfaces with a given fractal geometry. The flow and heat transport equations…
