In quantum computing, matrix product states (a type of tensor train) are used to compactly represent high-dimensional systems. We took that idea and applied it to options pricing. When Fourier pricing, TTs allow us to efficiently store the payoff and characteristic function, cutting the complexity from to . This is especially useful for highly parameterised models and multi-asset cases. Our innovation was using a HyperNetwork to construct the TTs, which is significant because creating the TTs directly isn't always feasible—traditional methods often fail for non-linear systems due to rapid growth in the bond dimension.
