Question 12

Definizione di Qubit

Answer 12

Un qubit è l’unità di informazione fondamentale nella computazione quantistica, analogo al bit nella computazione classica. Mentre un bit classico può essere in uno stato di 0 o 1, un qubit può esistere in una sovrapposizione quantica di entrambi gli stati contemporaneamente, grazie ai principi della meccanica quantistica. Questa caratteristica consente ai computer quantistici di elaborare informazioni in modi radicalmente diversi rispetto ai computer classici, offrendo potenziali vantaggi in termini di velocità e capacità computazionale per determinati tipi di problemi.
