m English fix.
Line 13:
Quantum query complexity is the smallest number of queries to the oracle that are required in order to calculate the function. This makes the quantum query complexity a lower bound on the overall time complexity of a function.
 
An example depicting the power of quantum computing is [[Grover's algorithm]] for searching unstructured databases. The algorithm's quantum query complexity is <math display="inline">O{\left(\sqrt{N}\right)}</math>, a quadraticallyquadratic improvement over the best possible classical query complexity (i.e. a [[linear search]]).
