Multiple choice
After this circuit, what is P(|111⟩) for the whole 3-qubit register measured together (qubit 0 leftmost)?
const c = circuit(3); c.h(0); // (|0>+|1>)/sqrt2 on qubit 0 c.cx(0, 1); // copy onto qubit 1 c.cx(0, 2); // copy onto qubit 2 -> (|000>+|111>)/sqrt2 return c;
Commit your prediction for P(|111⟩) — then run it.
