    "patent_abstract": "The present disclosure relates to a quantum state preparation circuit generation method and apparatus, a quantum chip, and an electronic device. The quantum chip may be applied to various intelligent terminals and on-board devices. The method includes: determining a first unitary operator respectively encoding r c qubits and r t qubits into a control register and a target register; acquiring at least two second unitary operators for performing phase shifting on the n qubits; determining a third unitary operator for replacing a qubit of the control register and a qubit of the target register; generating diagonal unitary matrix quantum circuits based on the first, second, third, fourth unitary operators, and a diagonal unitary matrix operator; combining the diagonal unitary matrix quantum circuits with a single-bit gate to obtain at least two uniform control gates; and combining the at least two uniform control gates into a quantum state preparation circuit.",
    "precision_class": "structural",
    "invention_explanation": "A method that converts desired quantum operations into smaller control and phase-shifting steps so a quantum chip can prepare a chosen state.",
