Quantum Stochastic Calculus as a Unifying Force in Physics and Probability
A survey is made of the theory of quantum stochastic calculus in Fock space developed by the author and K. R. Parthasarathy, together with some of its applications. Comparison with the classical Ito stochastic calculus of Brownian motion is emphasised, as is the power of the quantum theory to unify aspects of the classical theory of stochastic processes, Boson and Fermion second quantisation and dilations of quantum dynamical semigroups.
