Bits Hold 1 NumberQubits Can Hold All Numbers!

3-Bit Number

3-Qubit Number

Superposition makes

this possible

Tangent: Entanglement Happens When One Qubit’s State Depends on Another’s

Entangled

Not Entangled

If you measure the firstqubit and it’s 0, you knowthe second qubit is 0 too.They’re entangled!

If you measure the firstqubit and it’s 0, you don’tknow the second qubit.

They’re independent!

If n has the factors p and q,then, if you pick a random x,the above sequence has aperiod that evenly dividesinto (p-1)(q-1)
