The authors present a quantum algorithm for the pricing of options, a financial derivative, which works in the unary representation of the value of the underlying asset. Compared to a previous binary algorithm, the present one is designed to be simple in terms of logic operations and in terms of connectivity requirements, while still giving sufficiently accurate results with less than 100 qubits.
