A quantum version of a [[probability]] distribution, where each [[Qubits]] has some amplitude for being 1 and some amplitude of being 0 ![[Pasted image 20211002131004.png]] Superposition is the reason why it takes a vast number of classical bits to describe the quantum state of even a tiny number of particles Superposition is a **complex linear combination** - *Complex* as in real plus an imaginary number - *linear combination *means we add together different multiples of states
