How this entity was disambiguated
This entity first appeared as the object of triple T17028126 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

-
A.
Toffoli gate
The Toffoli gate is a universal reversible logic gate that extends the controlled-NOT operation to three bits, enabling reversible and quantum computation.
-
B.
Hadamard gate
The Hadamard gate is a fundamental single-qubit quantum logic gate that creates equal superpositions of basis states and is widely used in many quantum algorithms.
-
C.
Deutsch–Jozsa algorithm
The Deutsch–Jozsa algorithm is a foundational quantum algorithm that demonstrates how quantum computation can solve certain decision problems exponentially faster than any classical deterministic algorithm.
-
D.
Bennett's logical reversibility
Bennett's logical reversibility is a concept in computation theory stating that computational processes can be designed so that each step is logically reversible, allowing information to be recovered and, in principle, computation to occur without energy dissipation.
-
E.
Grover’s algorithm
Grover’s algorithm is a quantum search algorithm that provides a quadratic speedup over classical methods for finding a marked item in an unsorted database.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
