Logical NOT
Logical NOT is a unary Boolean operation that produces the complementary truth value of its operand.
Quantum Programming in Depth
Negation is the logical operation that changes a true value to false and a false value to true.
- How it is used
- Evaluates negated variables while constructing reversible circuits for Boolean expressions.
- How deep it goes
- Defines the truth-table behavior and gives a gate-level inversion and uncomputation procedure, without developing NOT beyond circuit synthesis.
- Examples
- Uses truth tables, negated CNF literals, clause evaluation, and temporary X-gate inversions as concrete demonstrations.
- What you can do after
- Build it from scratch by translating a negated Boolean literal into an X gate and uncomputing the temporary inversion.

A unary logical operation that inverts a binary input value.
- How it is used
- Deploys binary decision inversion as a component layered onto detectors and other machines.
- How deep it goes
- Defines inversion through real-world systems but stops short of implementation details or formal truth tables.
- Examples
- Uses an unauthorized-person alarm and a social-media friendship recommendation based on rock-music preferences.
- What you can do after
- Apply it to reverse a detector's binary output when the desired response corresponds to the opposite condition.
