Variational Quantum Models for Knowledge Graph Embeddings on NISQ Devices
Guido Bellomo, Martín Santesteban, Patricio Bruno +2
Variational Quantum Algorithms (VQAs) combine quantum circuits with classical optimization to tackle problems that may benefit from the capabilities of near-term quantum hardware.…

D. G. Bussandri, G. M. Bosyk, P. Crespo Del Amo +1
In this work, we introduce a comprehensive statistical framework for assessing single-qubit quantum teleportation performance beyond the conventional average-fidelity benchmark. At…

F. Meroi, M. Losada, G. M. Bosyk
In this study, we enhance the understanding of entanglement transformations and their quantification by extending the concept of Schmidt vector from pure to mixed bipartite states,…
Challenges in certifying quantum teleportation: moving beyond conventional fidelity benchmark
D. G. Bussandri, G. M. Bosyk, F. Toscano
The conventional certification method for quantum teleportation protocols relies on surpassing the highest achievable classical average fidelity between target and teleported state…
Optimal quantum teleportation protocols for fixed average fidelity
Fabricio Toscano, Diego G. Bussandri, Gustavo M. Bosyk +2
We demonstrate that among all quantum teleportation protocols giving rise to the same average fidelity, those with aligned Bloch vectors between input and output states exhibit the…
Simultaneous quantum estimation of phase and indistinguishability in a two photon interferometer
Laura T. Knoll, Gustavo M. Bosyk
With the rapid development of quantum technologies in recent years, the need for high sensitivity measuring techniques has become a key issue. In particular, optical sensors based…

Fabricio Toscano, Gustavo M. Bosyk, Steeve Zozor +1
Von Neumann entropy rate for open quantum systems is, in general, written in terms of entropy production and entropy flow rates, encompassing the second law of thermodynamics. When…
Generalized coherence vector applied to coherence transformations and quantifiers
G. M. Bosyk, M. Losada, C. Massri +2
One of the main problems in any quantum resource theory is the characterization of the conversions between resources by means of the free operations of the theory. In this work, we…

César Massri, Guido Bellomo, Federico Holik +1
Given a probability vector with its components sorted in non-increasing order, we consider the closed ball with formed by the probability vect…

We report a theoretical and experimental study on the role of indistinguishability in the estimation of an interferometric phase. In particular, we show that the quantum Fisher inf…
Optimal common resource in majorization-based resource theories
G. M. Bosyk, G. Bellomo, F. Holik +2
We address the problem of finding the optimal common resource for an arbitrary family of target states in quantum resource theories based on majorization, that is, theories whose c…

We study a version of the generalized (h, ϕ)-entropies, introduced by Salicrú et al, for a wide family of probabilistic models that includes quantum and classical statistical theor…

We propose a formal resource theoretic approach to asses the coherence between partially polarized electromagnetic fields. We show that naturally defined incoherent operations endo…
