Deutsch-Jozsa Algorithm

Switch between balanced and constant oracle families, run the circuit, and inspect the final measurement signature.

The lab frames Deutsch-Jozsa as an early lesson in interference-based algorithmic structure rather than a scalability claim.

Deutsch-Jozsa Algorithm

Deutsch-Jozsa works by engineering interference so one quantum query separates constant from balanced oracle families.

Outputs

Quantum queries1

Quantum oracle calls stay fixed.

Classical queries5

Classical worst-case queries for certainty.

Output101

Idealized final-register signature.

Constant oracles return the all-zero signature after the final Hadamards. Balanced oracles leave a non-zero pattern because the amplitudes cancel differently.
