This activity is a first step in learning about quantum computing,  introducing qubit states, Dirac and matrix notation, measurement probabilities, and single-qubit X, Z, H, and I gates. 

There is no prerequisite knowledge required for this activity, but previous classroom introduction to basic ideas and notation of quantum states (including Dirac and matrix notation) is useful.

This activity takes students through the BB84 quantum key distribution protocol. It uses quantum circuit notation and includes the effect of an eavesdropper.

Prerequisite knowledge: Basic single qubit gates (in particular, the Hadamard, H gate). Students should know how to predict probabilistic outcomes of measurements in the computational (Z) basis on superpositions of $|0\rangle, |1\rangle, |+\rangle, |-\rangle$ states.
