Square of white noise unitary evolutions on Boson Fock space

We prove the It\^{o} multiplication table for the stochastic differentials of the universal enveloping algebra of the square of white noise defined on Boson Fock space. Using the It\^{o} table we derive unitarity conditions for processes satisfying quantum stochastic differential equations in terms of such noise. Computer algorithms for checking these conditions, for computing the product of stochastic differentials, and for iterating the differential of the square of white noise analogue of the Poisson- Weyl operator are also provided.
