a The matrix B of Eq. (1), where each column represents a variable and each row represents an equation. b The first linear equation in B compiled as a circuit. The gate labelled “1” is a CNOT followed by a SWAP, as shown in the inset of (c). We use this circuit design to construct the full quantum circuit for Bx = y. c The quantum circuit built from B. Bij = 1 corresponds to the two-qubit gate shown in the inset, whereas Bij = 0 corresponds to a SWAP gate. The output state \({|\psi \rangle }_{{{{{{{{\rm{out}}}}}}}}}\) holds all y that yield solutions to Eq. (1) and the corresponding x for the matrix B. Throughout all panels, the variable labels are in light blue and the parity/equation labels are in dark blue.
