HHL Benchmark Circuit Generation.

Module Contents

create_circuit(num_qubits: int) → QuantumCircuit

HHL algorithm for a fixed 2x2 Hermitian matrix A using scalable QPE precision.

This implementation simulates a more accurate model of the HHL algorithm for the matrix A = [[1, 1], [1, 3]] with known eigenvalues.

Parameters:

num_qubits – Total number of qubits (1 system + phase-estimation register + 1 ancilla). Must be at least 3.

Returns:

QuantumCircuit – Qiskit circuit implementing HHL
