Two-qubit entanglement dynamics for two different non-Markovian environments
2009
We study the time behavior of entanglement between two noninteracting qubits each immersed in its own environment for two different non-Markovian conditions: a high-$Q$ cavity slightly off-resonant with the qubit transition frequency and a nonperfect photonic band-gap, respectively. We find that revivals and retardation of entanglement loss may occur by adjusting the cavity-qubit detuning, in the first case, while partial entanglement trapping occurs in non-ideal photonic-band gap.
Children Witnessing Domestic and Family Violence: A Widespread Occurrence during the Coronavirus Disease 2019 (COVID-19) Pandemic
2021
Across the world, children and adolescents are exposed daily to toxic levels of violent behaviors, including domestic and family violence. Violence increasingly has permeated and profoundly affected the lives of children, who are the most vulnerable members of society.1 Pediatric societies in Europe and North America have raised great concern over the effect that abusive experiences will have on present and future generations.1, 2, 3, 4 The global spread of coronavirus disease 2019 (COVID-19) during the past year has dramatically worsened the situation, contributing to a further increase in violence and aggression within households. Reports of domestic abuse and family violence have increas…
Le prove testimoniali nell’Apologia di Apuleio
2015
In Apuleius’ Apologia the witnesses play a relevant role and indeed, in some cases, they are crucial for the defensive speech. This survey explores in detail the universe of the characters and the evidences in the Apuleian oration. Testes are often presented in spectacular form: from Crassus’ comic tones to the scenic personification of verba suppressa from Pudentilla’s letter. In Apuleius’ words, you can also see a strong continuity with the rhetorical treatises and the previous oratorical tradition: undeniably there is a proximity between some choices in the Apologia and similar solutions in Cicero, as well and it is also possible, in particular, to read some sections of the Apuleian text…
Krytyka wybranych aspektów chrystologii świadków Jehowy w świetle książki Josepfa Ratzingera: Jezus z Nazaretu, cz. I: Od chrztu w Jordanie do Przemi…
2018
Pytanie Chrystusa zawarte we wszystkich ewangeliach synoptycznych: za kogo uważają Go ludzie i kim On jest dla apostołów, wydaje się być wciąż aktualne. Papież Benedykt XVI określa je jako „kamień milowy na drodze Jezusa”. Mimo rozwoju nauk humanistycznych, odpowiedzi jest wiele, a często są one sprzeczne. Niniejsza praca stanowi próbę krytyki wybranych elementów chrystologii świadków Jehowy w świetle obrazu Chrystusa ujętego w książce Josepha Ratzingera Jezus z Nazaretu, cz. I: Od chrztu w Jordanie do Przemienienia. Powyższe zestawienie wykazało, jak liczne i poważne są rozbieżności w postrzeganiu Jezusa przez organizację oraz Jego przedstawieniu w Biblii. Fakty te przemawiają za konieczno…
Entanglement dynamics in superconducting qubits affected by local bistable impurities
2012
We study the entanglement dynamics for two independent superconducting qubits each affected by a bistable impurity generating random telegraph noise (RTN) at pure dephasing. The relevant parameter is the ratio $g$ between qubit-RTN coupling strength and RTN switching rate, that captures the physics of the crossover between Markovian and non-Markovian features of the dynamics. For identical qubit-RTN subsystems, a threshold value $g_\mathrm{th}$ of the crossover parameter separates exponential decay and onset of revivals; different qualitative behaviors also show up by changing the initial conditions of the RTN. We moreover show that, for different qubit-RTN subsystems, when both qubits are …
PROVA TECNICA E CONTRADDITTORIO NEL PROCESSO PENALE
2023
When science and the criminal process come into contact, cognitive mechanisms are set in motion aimed at reorganizing knowledge belonging to worlds other than the legal one. In this context, the actors of the trial scene are forced to move on a hybrid terrain in which judicial epistemology and scientific epistemology mix. Such a fascinating picture pushes the scholar of the criminal process to seek interpretations suitable for explaining the multiple dilemmas that the phenomenon entails. Starting from a historical-legislative excursus of the expert evidence, the proposed analysis examines the different channels through which expert knowledge enters the process, starting from the investigati…
Expert witness in paternity testing in Germany.
2003
In Germany, paternity testing can be ordered by a judge as well as by private persons. In the case of private counselling, the expert has the duty to inform the parties on all medical, legal and ethical aspects. Informed consent must be given by each individual included in an exploration of family relationships. Due to the rapid progress of DNA typing in even minute amounts after polymerase chain reaction amplification, genotypes of short tandem repeat systems can be elicited by extraction from single cells. Therefore, the number of unlawful investigations of paternal relationships is steadily increasing. Here the requirements for paternity testing laboratories and sanctions for unlawful ex…
Celebrities, violencia de género y derechos de las mujeres: ¿hacia una transformación del marco de reconocimiento?
2016
espanolIntroduccion. Ante los limites que presenta el actual marco de reconocimiento de la violencia de genero, el presente trabajo analiza las posibilidades que abre la accion de celebrities en la transformacion de este marco y en relacion a la lucha por los derechos de las mujeres. Para ello proponemos el concepto de ethical witnessing. Metodologia. Se propone un modelo de analisis a traves de la operacionalizacion de dicho concepto para el estudio de practicas representacionales que puedan desestabilizar los actuales parametros de representacion en aras de la resignificacion del sujeto-victima de la violencia. Las cuatro dimensiones de analisis son: el tipo de relacion que se genera entr…
Universal N -Partite d -Level Pure-State Entanglement Witness Based on Realistic Measurement Settings
2019
Entanglement witnesses are operators that are crucial for confirming the generation of specific quantum systems, such as multipartite and high-dimensional states. For this reason, many witnesses have been theoretically derived which commonly focus on establishing tight bounds and exhibit mathematical compactness as well as symmetry properties similar to that of the quantum state. However, for increasingly complex quantum systems, established witnesses have lacked experimental achievability, as it has become progressively more challenging to design the corresponding experiments. Here, we present a universal approach to derive entanglement witnesses that are capable of detecting the presence …
Dynamics of correlations due to a phase noisy laser
2012
We analyze the dynamics of various kinds of correlations present between two initially entangled independent qubits, each one subject to a local phase noisy laser. We give explicit expressions of the relevant quantifiers of correlations for the general case of single-qubit unital evolution, which includes the case of a phase noisy laser. Although the light field is treated as classical, we find that this model can describe revivals of quantum correlations. Two different dynamical regimes of decay of correlations occur, a Markovian one (exponential decay) and a non-Markovian one (oscillatory decay with revivals) depending on the values of system parameters. In particular, in the non-Markovia…
