Episode 5 spotlights quantum oracles—both ancilla-flip and streamlined phase-oracle forms—demonstrating on two- and three-qubit circuits how to mark target basis states for later detection in a quantum algorithm. With the oracle in place, you implement amplitude amplification: repeated oracle calls followed by the diffusion operator gradually concentrate probability on those marked states, making them stand out in measurement statistics. Mastering these techniques—quantum oracles, amplitude amplification, diffusion operator, marked states—gives you the essential building blocks for the advanced algorithms coming up.
