Card #c99IR // #c99Synthesis

If a measurement is not taken, the qubit will be in a superposition of |0⟩ and |1⟩, and its onward evolution can involve the interference of these two components.

[Use when]

When explaining why you cannot peek mid-algorithm without killing the advantage.

[Why it matters]

Superposition is useful only while uncollapsed — interference is the payload.
