Second-order moment equivalence of twisted Gaussian Schell model beams and orbital angular momentum eigenmodes
T. Ferreira, G. Santos, S. Ayala +5
We show that the covariance matrix of any cylindrically symmetric coherent orbital angular momentum (OAM) eigenmode with quantum number takes a universal form depending only…
Evaluation of Twisted Gaussian Schell Model beams produced with phase randomized coherent fields
Gustavo Cañas, Esteban Sepúlveda Gómes, Gustavo Henrique dos Santos +6
The twisted Gaussian Schell Model describes a family of partially coherent beams that present several interesting characteristics, and as such have attracted attention in classical…
Optimal strategy to certify quantum nonlocality
S. Gómez, D. Uzcategui, I. Machuca +4
Certification of quantum nonlocality plays a central role in practical applications like device-independent quantum cryptography and random number generation protocols. These appli…
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…
Multi-dimensional entanglement generation with multi-core optical fibers
E. S. Gómez, S. Gómez, I. Machuca +4
Trends in photonic quantum information follow closely the technical progress in classical optics and telecommunications. In this regard, advances in multiplexing optical communicat…
Tunable entanglement distillation of spatially correlated down-converted photons
E. S. Gómez, P. Riquelme, M. A. Solis-Prosser +4
We report on a new technique for entanglement distillation of the bipartite continuous variable state of spatially correlated photons generated in the spontaneous parametric down-c…
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…
Device-Independent Certification of a Nonprojective Qubit Measurement
Esteban S. Gómez, Santiago Gómez, Pablo González +8
Quantum measurements on a two-level system can have more than two independent outcomes, and in this case, the measurement cannot be projective. Measurements of this general type ar…
Five measurement bases determine pure quantum states on any dimension
D. Goyeneche, G. Cañas, S. Etcheverry +4
A long standing problem in quantum mechanics is the minimum number of observables required for the characterisation of unknown pure quantum states. The solution to this problem is…
Applying the simplest Kochen-Specker set for quantum information processing
Gustavo Cañas, Mauricio Arias, Sebastián Etcheverry +4
Kochen-Specker (KS) sets are key tools for proving some fundamental results in quantum theory and also have potential applications in quantum information processing. However, so fa…
Quantum key distribution session with 16-dimensional photonic states
S. Etcheverry, G. Cañas, E. S. Gómez +4
The secure transfer of information is an important problem in modern telecommunications. Quantum key distribution (QKD) provides a solution to this problem by using individual quan…
Quantifying the non-Gaussianity of the state of spatially correlated down-converted photons
E. S. Gómez, W. A. T. Nogueira, C. H. Monken +1
The state of the spatially correlated down-converted photons is usually treated as a two-mode Gaussian entangled state. While intuitively this seems to be reasonable, it is known t…
Bell scenarios in which nonlocality and entanglement are inversely related
G. Vallone, G. Lima, E. S. Gómez +4
We show that for two-qubit chained Bell inequalities with an arbitrary number of measurement settings, nonlocality and entanglement are not only different properties but are invers…
Experimental quantum tomography of photonic qudits via mutually unbiased basis
G. Lima, L. Neves, R. Guzmán +5
We present the experimental quantum tomography of 7- and 8-dimensional quantum systems based on projective measurements in the mutually unbiased basis (MUB-QT). One of the advantag…
