Question

Consider the following statements about 'Quantum Computing'.
$1$. Qubits is the smallest unit of Quantum Computing.
$2$. A Qubit can have only $2$ values, either $1$ or $-1$.
Which of the given statement(s) is/are correct?

• A. $1$ only
• B. $2$ only
• C. Both $1$ and $2$
• D. Neither $1$ nor $2$

Answer 1

The correct option is A $1$ only

In a normal computer, information is stored as bits (either zero or one). Instead of this, a quantum computer has quantum bits. Quantum computers work on Qubits. Qubits work faster because of the way such circuits are designed. A Qubit or quantum bits may be 0, 1 or any value between them superimposed to appear 0 or 1.
