PRESENTAZIONE BIT QUANTISTICO

Il bit quantistico
PRESENTAZIONE DI LORENZO MAZZOCCHETTI ANNO 2019/2020

Cos’è il bit quantistico
IL BIT QUANTISTICO (O QUBIT) È IL CORRISPONDENTE DEL BIT CLASSIC O NELLA NUOVA
BRANCA DELL'INFORMATICA, OVVERO "L'INFORMATICA QUANTISTICA"
ESSA SI BASA SULLA TEORIA DEI QUANTI E SUI PRINCIPI DELLA FISICA QUNTISTICA ; LA
DIFFERENZA TRA IL BIT ED IL QUBIT È DAL NUMERO DEI VALORI CHE PO SSONO
ASSUMERE: IL PRIMO PUÒ ASSUMERE DUE VALORI "0" E "1" MENTRE IL S ECONDO PUÒ
ASSUMERLI CONTEMPORANEMANTE.
NEL QUBIT,CHE RISPONDE AL "PRINCIPIO DI INDETERMINAZIONE" DI HEI SENBERG, LA
PARTICELLE SI TROVA IN UNO STATO DI"SOVRAPPOSIZIONE" E SI COMPOR TA COME SE
FOSSE SIA IN UNO STATO DI SPIN-UP CHE IN STATO DI SPIN-DOWN,CIÒ COMPORTA LA
CAPACITÀ DI ASSUMERE I DUE VALORI CONTEMPORANEAMENTE.

Le caratteristiche del qubit
TELETRASPORTO QUANTICO
Le particelle coinvolte in questo
processo, mantengono una
correlazione che permette una
connessione tra di loro,tramite ciò
sapendo lo spin della prima
particella si è a conoscenza anche
delle seconda (che sarà l'opposto
della prima).
Tutto questo permette di trasferire
in maniera instantanea informazioni
a qualsiasi distanza operando un
vero e proprio teletrasporto.
MAGGIORE POTENZA
La possibilità di assumere due
valori e l’incredibile velocità di
trasferimento dei dati
permettono al sistema di avere
una maggiore potenza dovuto
alla maggior possibilità di
archiviazione tramite il qubit.

La potenza del
nuovo computer
qubit di google
L’azienda,tramite un paper
pubblicato su Nature, e in un post sul
proprio blog ufficiale, ha reso note le
incredibili capacità del suo nuovo
supercomputer, Sycamore, che
utilizza appunto i bit quantistici.
Secondo Google la macchina è in
grado di eseguire in 200 secondi
calcoli che il più potente dei
computer a bit classici ,ovvero il
Summit creato da IBM, sarebbe in
grado di completare in 10000 anni.

Le dichiarazioni di Google
L'azienda ha paragonato la scoperta al primo volo dei
fratelli Wright mentre Sundar Pichai, quarantesettenne
CEO di Google si è espresso molto entusiasta del nuovo
obiettivo raggiunto.
Lo stesso in un' intervista alla rivista di tecnologia del
MIT di Boston ha dichiarato che "il vero entusiasmo
riguardo la supremazia quantistica viene dal fatto che
fondamentalmente l'universo naturale funziona così, in
un "modo quantistico", quindi potremmo finalmente
comprenderlo meglio« ,mentre, per le tempistiche
relative ad un vero e proprio utilizzo, Pichai prevede un
attesa di circa un decennio.

La risposta della comunità informatica
Dopo le dichiarazioni sul proprio blog personale da parte
di google, IBM, azienda costruttrice di elettronica e di
Summit,il computer tradizionale più potente del
mondo,non è convinta fermamente della supremazia del
qubit, sostenendo che le operazioni eseguite siano state
eseguite in un ambito ristretto poco utili all'applicazione
nella vita comune

Problemi vari
Il beat quantistico presenta diversi problemi: deve essere isolato,
lontano da qualsiasi interferenza, per non collassare durante i calcoli, è
difficile intervenire in caso di errori ed nel caso di dover recuperare dati
in uscita, variazioni di temperatura e vibrazioni possono alternare
l'equilibrio quantico ed ostacolare il processo di calcolo
Infine diversi sono scettici sul fatto che venga eseguito il processo
descritto in teoria, tanto che vengono eseguiti test di calcolo possibili
solo col processo teorizzato con i principi precedentemente elencati.
La strada è ancora lunga , ma ,sicuramente , le scoperte nel campo
hanno sorpreso ed attirato l'attenzione mondiale quindi non possiamo
fare altro che aspettare e godere di un altro incredibile passo in avanti
della tecnologia moderna

How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow

��

Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits. To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups. Technology For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did. While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis. Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad. Age and Gender When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same. Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers. Race Affects Attitudes As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

AI Trends in Creative Operations 2024 by Artwork Flow.pdfmarketingartwork

Creative operations teams expect increased AI use in 2024. Currently, over half of tasks are not AI-enabled, but this is expected to decrease in the coming year. ChatGPT is the most popular AI tool currently. Business leaders are more actively exploring AI benefits than individual contributors. Most respondents do not believe AI will impact workforce size in 2024. However, some inhibitions still exist around AI accuracy and lack of understanding. Creatives primarily want to use AI to save time on mundane tasks and boost productivity.

Organizational culture includes values, norms, systems, symbols, language, assumptions, beliefs, and habits that influence employee behaviors and how people interpret those behaviors. It is important because culture can help or hinder a company's success. Some key aspects of Netflix's culture that help it achieve results include hiring smartly so every position has stars, focusing on attitude over just aptitude, and having a strict policy against peacocks, whiners, and jerks.

Google's Just Not That Into You: Understanding Core Updates & Search IntentLily Ray

��

1. Core updates from Google periodically change how its algorithms assess and rank websites and pages. This can impact rankings through shifts in user intent, site quality issues being caught up to, world events influencing queries, and overhauls to search like the E-A-T framework. 2. There are many possible user intents beyond just transactional, navigational and informational. Identifying intent shifts is important during core updates. Sites may need to optimize for new intents through different content types and sections. 3. Responding effectively to core updates requires analyzing "before and after" data to understand changes, identifying new intents or page types, and ensuring content matches appropriate intents across video, images, knowledge graphs and more.
