Quantum oracle calls stay fixed.
Simulation studio
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.

Live lab
Interactive simulation workspace
These academy-style labs are designed as compact, browser-playable teaching surfaces: enough interaction to make the core idea legible, without pretending to be a full research workbench.
Interactive academy lab
Deutsch-Jozsa Algorithm
Deutsch-Jozsa works by engineering interference so one quantum query separates constant from balanced oracle families.
Controls
Outputs
Classical worst-case queries for certainty.
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.
