|q⟩ Bad Qubits

← Question Bank

Multiple choice
This circuit is measured once in the computational basis. What is P(|010⟩)?
⚛ The apparatus
const c = circuit(3);
c.h(0);
c.cx(0, 1);
c.cx(0, 2); // encode |+_L>
c.x(1);     // injected bit-flip error on qubit 1
// Decode: run the encoder backwards (CNOT is its own inverse).
c.cx(0, 1);
c.cx(0, 2);
// Coherent majority correction: flip qubit 0 iff both partners say "1".
c.ccx(2, 1, 0);
return c;
