Multiple choice
After this circuit, what is P(|11⟩) for the whole 2-qubit register measured together (qubit 0 leftmost)?
// H on qubit 0 makes (1/sqrt2)(|00> + |10>); CNOT(0->1) flips target when // control is 1, sending |10> -> |11>, giving the Bell state |Phi+>. const c = circuit(2); c.h(0); c.cx(0, 1); return c;
