Enhanced discrimination of high-dimensional quantum states by concatenated optimal measurement strategies
M. A. Solís-Prosser, O. Jiménez, A. Delgado +1
The impossibility of deterministic and error-free discrimination among nonorthogonal quantum states lies at the core of quantum theory and constitutes a primitive for secure quantu…
Ptychographic reconstruction of pure quantum states
M. F. Fernandes, M. A. Solís-Prosser, L. Neves
The quantum analogue of ptychography, a powerful coherent diffractive imaging technique, is a simple method for reconstructing -dimensional pure states. It relies on measuring p…
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…
Photonic Discrete-time Quantum Walks and Applications
Leonardo Neves, Graciana Puentes
We present a review of photonic implementations of discrete-time quantum walks (DTQW) in the spatial and temporal domains, based on spatial- and time-multiplexing techniques, respe…
Ptychography of pure quantum states
Mário Foganholi Fernandes, Leonardo Neves
Ptychography is an imaging technique in which a localized illumination scans overlapping regions of an object and generates a set of diffraction intensities used to computationally…
Proposal for Automated Operations for Single-Photon Multipath Qudits
Roberto D. Baldijão, Gilberto F. Borges, Breno Marques +3
We propose a method for implementing automated state transformations on single-photon multipath qudits encoded in a one-dimensional transverse spatial domain. It relies on transfer…
