Spot the math the sketches must get right (including common off-by-one bugs in iteration counts).

Warm up: pick the matching equation among lookalikes (same walk as the theory lesson).

Activity: $ZZ$ diagonal

For $H\propto XX+YY+ZZ-3ZZ$, the $|00\rangle$ diagonal entry of $XX+YY+ZZ-3ZZ$ equals $-2$ (from $ZZ-3ZZ=-2ZZ$ and $XX,YY$ zeros on that slot). Print that diagonal value with 10 decimals.

Using “sqrt”, “N”, and “qubits”, explain:

In a Grover driver, should π√·/4 use the number of qubits n or the search space size N=2ⁿ?

Minimum 3 words. Your answer must include: “sqrt”, “N”, “qubits”.
