# Nbed

Projection-based embedding is a method for framenting a molecular system so that a computationally expensive method can be applied to an _active region_ of interest, while the _environment_ is simulated with a cheaper approxmimate method.

As a result, it is possible to obtain more accurate results than the cheaper method alone, while using significantly fewer computational resources than applying the expensive method to the whole system.

`nbed` is designed with application to quantum compting in mind, outputting a reduced dimension second quantised Hamiltonian which can be solved using any quantum simulation algorithm.
