  Gamification of quantum theory can provide new inroads into the subject: by
allowing users to experience simulated worlds that manifest obvious quantum
behaviors they can potentially build intuition for quantum phenomena. The Qubit
Factory is an engineering-style puzzle game based on a gamified quantum circuit
simulator that is designed to provide an introduction to qubits and quantum
computing, while being approachable to those with no prior background in the
area. It introduces an intuitive visual language for representing quantum
states, gates and circuits, further enhanced by animations to aid in
visualization. The Qubit Factory presents a hierarchy of increasingly difficult
tasks for the user to solve, where each task requires the user to construct and
run an appropriate classical/quantum circuit built from a small selection of
components. Earlier tasks cover the fundamentals of qubits, quantum gates,
superpositions and entanglement. Later tasks cover important quantum algorithms
and protocols including superdense coding, quantum teleportation, entanglement
distillation, classical and quantum error correction, state tomography, the
Bernstein-Vazirani algorithm, quantum repeaters and more.
