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…
Minimum optical depth multiport interferometers for approximating arbitrary unitary operations and pure states
Luciano Pereira, Alejandro Rojas, Gustavo Lima +3
Reconfigurable devices which can implement arbitrary unitary operations are crucial for photonic quantum computation, optical neural networks, and boson sampling. Here, we address…
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…
