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…
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…
Experimental quantum tomography assisted by multiply symmetric states in higher dimensions
D. Martínez, M. A. Solís-Prosser, G. Cañas +3
High-dimensional quantum information processing has become a mature field of research with several different approaches being adopted for the encoding of -dimensional quantum sy…
