Abstract
A method and device for quantum division operation with precision. The method includes: obtaining dividend data and divisor data to be operated, transforming the dividend data into a first target quantum state, and transforming the divisor data into a second target quantum state; for the first target quantum state and the second target quantum state, iteratively executing quantum state evolution corresponding to a subtraction operation, counting the number of executions of the subtraction operation until the dividend data is reduced to a negative number, and outputting a finally obtained counting result as integer part of a quotient of dividing the dividend data by the divisor data; for a current first target quantum state and a current second target quantum state, iteratively executing quantum state evolution corresponding to fractional part operation of the quotient; and outputting a finally obtained quantum state on a qubit with preset precision bits.
