Quantum superposition is the ability to exist in multiple states simultaneously. In other words, it's like being in two places at once. But, you know, not just places, but states of mind, like "hungry" and "not-hungry" at the same time. It's all very confusing, but trust us, it's real.

Here's an equation to illustrate it: | ψ = ∑ (a_i |a_i›). This is a fancy way of saying "you're in multiple states, but you're also in none of them". Don't ask us to explain it, we've already lost the plot.
