Power of an operation

Learn Power of an operation in Q# with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.

12 min read • Intermediate

Power of an operation is an atomic Q# topic inside Adjoint & Controlled. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what Power of an operation changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.

Topic-specific example

qsharp-05-10-power-of-an-operation.qs
qsharp Try It Live 
operation RepeatX(q : Qubit) : Unit { for _ in 1..3 { X(q); } }
Edge case / engineering note

Change the key input in this Q# example and predict the result first; the named construct should be the reason the behavior changes.
