A unified fidelity-based framework for quantum speed limits in open quantum systems
Tristán M. Osán, Yanet Álvarez, Mariela Portesi +1
In this work, we investigate the role of functionals of generalized fidelity measures in deriving quantum speed limits (QSLs) within a geometric approach. We establish a general th…
Quantum imaginary time evolution and UD-MIS problem
Victor A. Penas, Marcelo Losada, Pedro W. Lamberti
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…
Rényi-Holevo inequality from --Rényi relative entropies
Diego G. Bussandri, Grzegorz Rajchel-Mieldzioć, Pedro W. Lamberti +1
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-…
Transmission distance in the space of quantum channels
Diego G. Bussandri, Pedro W. Lamberti, Karol Życzkowski
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…
Segmentation of quantum generated sequences by using the Jensen-Shannon divergence
Marcelo Losada, Víctor A. Penas, Federico Holik +1
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…
Generalized Holevo theorem and distinguishability notions
Diego G. Bussandri, Pedro W. Lamberti
We present a generalization of the Holevo theorem by means of distances used in the definition of distinguishability of states, showing that each one leads to an alternative Holevo…
