File StochasticNoiseOperationTable.hpp

Data structure for caching computed results of stochastic operations.

Self-contained copy of the MQT Core dd::StochasticNoiseOperationTable that was removed alongside the density-matrix support. The number of cached operations is provided explicitly instead of being derived from the (removed) noise OpTypes.
