Quantum circuit for gradient descent. and denote the initial state of the work system and ancilla syetem, respectively. The controlled operations that acted on the work system are . denotes number Hadamard gates. At the end of the circuit, we measure the final state of the ancilla registers. If all ancilla qubits are , the work systerm collapses into state .
