3D compact photonic circuits for realizing quantum state tomography of qudits in any finite dimension
Wilder Cardoso, Davi Barros, Leonardo Neves +1
In this work, we propose three-dimensional photonic circuit designs that guarantee a considerable reduction in the complexity of circuits for the purpose of performing quantum stat…

Implementing positive-operator-valued-measurement elements in photonic circuits for performing minimum quantum state tomography of path qudits
W. R. Cardoso, D. F. Barros, M. R. Barros +1
Manipulation of qudits in optical tables is a difficult and nonscalable task. The use of integrated optical circuits opens new possibilities for the generation, manipulation, and c…

Fock-state superradiance in a cold atomic ensemble
D. F. Barros, L. F. Muñoz-Martínez, L. Ortiz-Gutiérrez +7
A simplified theory for the wavepackets of the photons emitted during the read process of a quantum memory formed by cold atoms is provided. We arrive at analytical expressions for…
