HHL

diffqc.lib.HHL(op, c: Array, wires: Tuple[int], U: Array, aux: Tuple[int], anc: int) → Array

Solving Linear Equation with Harrow-Hassidim-Lloyd Algorithm

Solve A|x> = |b> and get |x> = A^(-1)|b> .

Parameters

• op – dense or sparse module

• c (jnp.ndarray) – qubits state

• wires (tuple of ints) – wires. |b>

• U (jnp.ndarray) – unitary matrix of exp(iA)

• aux (tuple of ints) – auxiliary qubits for QPE. These should be |00...0>

• anc (int) – ancilla qubits for HHL

Returns

applied qubits state.

Return type

jnp.ndarray
