Build a One-Qubit Superposition Circuit
Describe how a Hadamard gate changes a one-qubit state and how measurement samples it.
You need to explain a one-qubit circuit to a teammate who has seen the word superposition but has not run a circuit. Initialize -> transform amplitudes -> measure -> interpret shots The common shortcut is saying "Hadamard makes the bit random." That skips amplitudes and makes the gate sound like a classical coin-flip operation. Initialize Prepare one qubit in |0>. This gives a known starting basis state. A circuit needs a known initial state so the effect of the gate is interpretable. Transform Apply H to |0>. The resulting state has equal-magnitude amplitudes on |0> and |1>. The Hadamard does…
