A quantum bit, or qubit, is a state of the form a|0)+1 a0)+B|1) Where a,B∈ are called amplitudes, satisfying that a|2+|62=1. So a qubit can sit anywhere between 0 and 1(on the unit A quantum bit circle) (qubit We say that the state is in superposition of 0)and 1)• A quantum bit, or qubit, is a state of the form 𝛼 0 + 𝛽 1 where 𝛼, 𝛽 ∈ ℂ are called amplitudes, satisfying that 𝛼 2 + 𝛽 2 = 1. • So a qubit can sit anywhere between 0 and 1 (on the unit circle). • We say that the state is in superposition of 0 and 1 . A quantum bit (qubit) 𝛼 0 + 𝛽 1 0 1
