Quantum Stochastic Calculus Associated With Quantum Lévy White Noise

Mathematical Methods in the Applied Sciences
ABSTRACTWe establish the commutation relations of the quantum Lévy operators, consisting of the generalized Lévy Gross Laplacian and its adjoint, annihilation operator, creation operator, and the Lévy number operator. In particular, such quantum Lévy operators span a nonsolvable ‐Lie algebra.

Exponential formulae in quantum stochastic calculus

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1996
The rigorous definition of time-ordered exponentials, solving quantum linear stochastic differential equations, is extended to Boson and Fermion stochastic calculi with infinitely many degrees of freedom. The relation to the classicalmultiplicative stochastic integral, solving the Doleans exponential equation, is discussed.

Wick Calculus of Generalized Operators and its Applications to Quantum Stochastic Calculus

Infinite Dimensional Analysis, Quantum Probability and Related Topics, 1998
A nonlinear and stochastic analysis of free Bose field is established in the framework of white noise calculus. Wick algebra structure is introduced in the space of generalized operators generated by quantum white noise, some fundamental properties of the calculus based on the Wick algebra are investigated.

Stochastic dilations of quantum dynamical semigroups using one-dimensional quantum stochastic calculus

1990
We show that every norm continuous one-parameter semigroup (ℐt: t ∈ ℝ+) of unital ultraweakly continuous completely positive maps on the algebra ℬ(ℋ0) of bounded operators on the separable infinite dimensional Hilbert space ℋ0 can be expressed as Open image in new window where (j t : t ∈ ℝ+) is a quantum diffusion over ℬ(ℋ0) constructed using only ...

A Quantum Stochastic Calculus

2012
Martingales are fundamental stochastic process used to model the concept of fair game. They have a multitude of applications in the real world that include, random walks, Brownian motion, gamblers fortunes and survival analysis, Just as commutative integration theory may be realised as a special case of the more general non-commutative theory for ...

Quantum Stochastic Calculus and Applications — A Review

1998
It has been a little more than a decade since this subject, as it is understood today, came into being with the seminal paper of Hudson and Parthasarathy [1]. Since then the subject has seen rapid development and many of these can be found in the monographs of Parthasarathy [2] and Meyer [3]. Here I want to discuss some of the more recent developments.
