Engineering entangled photons for transmission in ring-core optical fibers
G. Cañas, E. S. Gómez, E. Baradit +2
The capacity of optical communication channels can be increased by space division multiplexing in structured optical fibers. Radial core optical fibers allows for the propagation o…
Optimal conditions for multiplexing information into ring-core optical fibers
Santiago Rojas-Rojas, Gustavo Cañas, Gabriel Saavedra +3
In optical communications, space-division multiplexing is a promising strategy to augment the fiber network capacity. It relies on modern fiber designs that support the propagation…
High-accuracy adaptive quantum tomography for high-dimensional quantum systems
L. Pereira, D. Martínez, G. Cañas +4
The accuracy of estimating -dimensional quantum states is limited by the Gill-Massar bound. It can be saturated in the qubit () scenario using adaptive standard quantum tom…
Self-testing mutually unbiased bases in higher dimensions with space-division multiplexing optical fiber technology
Máté Farkas, Nayda Guerrero, Jaime Cariñe +2
In the device-independent quantum information approach, the implementation of a given task can be self-tested solely from the recorded statistics and without detailed models for th…
Estimation of pure states using three measurement bases
L. Zambrano, L. Pereira, D. Martínez +3
We introduce a new method to estimate unknown pure -dimensional quantum states using the probability distributions associated with only three measurement bases. Measurement resu…
Multi-core fiber integrated multi-port beamsplitters for quantum information processing
J. Cariñe, G. Cañas, P. Skrzypczyk +10
Multi-port beamsplitters are cornerstone devices for high-dimensional quantum information tasks, which can outperform the two-dimensional ones. Nonetheless, the fabrication of such…
