Binary decisions are the simplest type of decisions that we make in our everyday lives. Examples include choosing a two-way path in a maze, accepting or declining an offer, etc. These decisions are also made by computers, machines and electronic components. But decisions made on these devices can be partial and deterministic. Here we present a simple framework to implement binary decisions using one or many qubits. Such systems are based on a separate hardware infrastructure rather than computer codes. The multi-armed bandit problem is used to highlight the decision making ability of qubits.
