• Abstract: Two indispensable algorithms in an introductory course on Quantum Computing are Grover's search algorithm and quantum phase estimation. Quantum counting is a simple yet beautiful blend of these two algorithms, and it is therefore an attractive topic for a student project in such a course. However, a sign that is irrelevant when implementing Grover's algorithm becomes relevant. We briefly review these algorithms, highlighting the aforementioned sign.
