QPE

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

Quantum Phase Estimation

Parameters

• op – dense or sparse module

• c (jnp.ndarray) – qubits state

• wires (tuples of ints) – wires. Eigen vector of U has been encoded.

• U (jnp.ndarray) – unitary matrix of which eigen value phase is estimated

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

Returns

applied qubits state. Phase is encoded at auxiliary qubits.

Return type

jnp.ndarray
