Six of these tapes are short quizzes, and they assume you already read kets, know the Pauli gates and can place a state on the Bloch sphere. If that is new, start with Learn. Choose a tape to play it. Qubit Factory loads into the deck below, and each quiz opens on its own page.

• Qubit Factory runs one- and two-qubit circuits and counts a hundred fresh runs.
• Which Gate asks which gate took one Bloch vector to another.
• Which Matrix asks what a product of gates equals, phase included.
• Which State asks whether a state is pure product, pure entangled, mixed or not a state.
• Which Measurement asks which basis or parity check does a job.
• Which Outcome asks for odds, expectation values and the state left behind.
• Which Algorithm names an algorithm from its spec sheet.
• Quantum Tycoon is the longer game, on its own site.
