Three qubits, no superposition, no entanglement: put the register into |101⟩ with certainty. The only difficulty is the labelling. Bars are printed MSB-first — q2 q1 q0 — so |101⟩ means q2 = 1, q1 = 0, q0 = 1. Get the wrong qubit and the histogram will tell you immediately.
Select a gate to see what it does, then tap a wire — or Tab to a wire and press Enter — to place it.
