Quantum imaginary time evolution and UD-MIS problem

Autor: Penas, Victor A., Losada, Marcelo, Lamberti, Pedro W.

In this work we apply a procedure based on the quantum imaginary time evolution method to solve the unit-disk maximum independent set problem. Numerical simulations were performed for instances of 6, 8 and 10-qubits graphs. We have found that the fai

R\'enyi-Holevo inequality from $\alpha$-$z$-R\'enyi relative entropies

Autor: Bussandri, Diego G., Rajchel-Mieldzioć, Grzegorz, Lamberti, Pedro W., Życzkowski, Karol

We investigate bounds in the transmission of classical information through quantum systems. Our focus lies in the generalized Holevo theorem, which provides a single-letter Holevo-like inequality from arbitrary quantum distance measures. Through the

Segmentation of quantum generated sequences by using the Jensen-Shannon divergence

Autor: Losada, Marcelo, Penas, Víctor A., Holik, Federico, Lamberti, Pedro W.

The Jensen-Shannon divergence has been successfully applied as a segmentation tool for symbolic sequences, that is to separate the sequence into subsequences with the same symbolic content. In this work, we propose a method, based on the the Jensen-S

Transmission distance in the space of quantum channels

Autor: Bussandri, Diego G., Lamberti, Pedro W., Życzkowski, Karol

We analyze two ways to obtain distinguishability measures between quantum maps by employing the square root of the quantum Jensen-Shannon divergence, which forms a true distance in the space of density operators. The arising measures are the transmis

Publikováno v: IMA Fungus, Vol 15, Iss 1, Pp 1-12 (2024)

Abstract The debates over the requirement of the International Code of Nomenclature for algae, fungi, and plants (ICNafp) for a viable specimen to represent the name-bearing type material for a species or infraspecific taxon have a long history. Taxo

Rao-Burbea centroids applied to the statistical characterisation of time series and images through ordinal patterns

Autor: Mateos, Diego M., Riveaud, Leonardo E., Lamberti, Pedro W.

Divergences or similarity measures between probability distributions have become a very useful tool for studying different aspects of statistical objects such as time series, networks and images. Notably not every divergence provides identical result
