Point tomography is a new approach to the problem of state estimation, which is arguably the most efficient and simple method for modern high-precision quantum information experime…
A new architecture for high speed core-selective switch for multicore fibers
Cristóbal Melo, Matías Reyes. F., Diego Arroyo +6
The use of multicore optical fibers is now recognized as one of the most promising methods to implement the space-division multiplexing techniques required to overcome the impendin…
All-in-fiber dynamic orbital angular momentum mode sorting
Alvaro Alarcón, Santiago Gómez, Daniel Spegel-Lexne +5
The orbital angular momentum (OAM) spatial degree of freedom of light has been widely explored in many applications, including telecommunications, quantum information and light-bas…
Certification of a Nonprojective Qudit Measurement using Multiport Beamsplitters
Daniel Martínez, Esteban S. Gómez, Jaime Cariñe +5
Generalised quantum measurements go beyond the textbook concept of a projection onto an orthonormal basis in Hilbert space. They are not only of fundamental relevance but have also…
Maximizing Post-selected Quantum Correlations from Classical Interference in a Multi-core Fiber Beamsplitter
J. Cariñe, M. Asan-Srain, G. Lima +1
Fourth-order interference is an information processing primitive for photonic quantum technologies. When used in conjunction with post-selection, it forms the basis of photonic con…
Polarization-independent single-photon switch based on a fiber-optical Sagnac interferometer for quantum communication networks
A. Alarcón, P. González, J. Cariñe +2
An essential component of future quantum networks is an optical switch capable of dynamically routing single-photons. Here we implement such a switch, based on a fiber-optical Sagn…
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…
Computational advantage from quantum superposition of multiple temporal orders of photonic gates
Márcio M. Taddei, Jaime Cariñe, Daniel Martínez +9
Models for quantum computation with circuit connections subject to the quantum superposition principle have been recently proposed. There, a control quantum system can coherently d…
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…
Challenging local realism with human choices
The BIG Bell Test Collaboration, C. Abellán, A. Acín +105
A Bell test is a randomized trial that compares experimental observations against the philosophical worldview of local realism. A Bell test requires spatially distributed entanglem…
Certifying an irreducible 1024-dimensional photonic state using refined dimension witnesses
Edgar A. Aguilar, Máté Farkas, Daniel Martínez +7
We report on a new class of dimension witnesses, based on quantum random access codes, which are a function of the recorded statistics and that have different bounds for all possib…
High-dimensional decoy-state quantum key distribution over 0.3 km of multicore telecommunication optical fibers
G. Cañas, N. Vera, J. Cariñe +11
Multiplexing is a strategy to augment the transmission capacity of a communication system. It consists of combining multiple signals over the same data channel and it has been very…
Experimental demonstration of the connection between quantum contextuality and graph theory
Gustavo Cañas, Evelyn Acuña, Jaime Cariñe +5
We report a method that exploits a connection between quantum contextuality and graph theory to reveal any form of quantum contextuality in high-precision experiments. We use this…
Postselection-Loophole-Free Bell Test Over an Installed Optical Fiber Network
