Hi(adsbygoogle = window.adsbygoogle || []).push({});

I read this information about the Qubit:

"N Qubits are equivalent 2^N classical bits (2^N states)"

But I couldn't understand that, because I know that each single Qubit could be one and zero at the same time, so each single Qubit is equivalent two classical bits (two states)

That mean:

If we have 3 Qubits it will be equivalent 6 classical bits(from 3×2)

If we have N Qubits it will be equivalent N×2 classical bits (not 2^N)

So can any one tell me what is my misconception ?
