Quantum noise and stochastic reduction
Abstract. In standard nonrelativistic quantum mechanics the expectation of the energy is a conserved quantity. It is possible to extend the dynamical law associated with the evolution of a quantum state consistently to include a nonlinear stochastic component, while respecting the conservation law. According to the dynamics thus obtained, referred to as the energy-based stochastic Schrödinger e...
متن کاملQuantum Black Noise and Generalized Quantum Stochastic Equations
A notion of quantum black noise is considered. Quantum black noise is an analogue of quantum white noise but it acts in a Fock space with indefinite metric. Quantum white noise describes the leading term in the stochastic limit approximation to quantum dynamics while quantum black noise describes corrections to the leading term. We obtain and study generalized quantum stochastic equations descr...
متن کاملQuantum Multipole Noise and Generalized Quantum Stochastic Equations
A notion of quantum multipole (in particular, dipole) noise is considered. Quantum dipole noise is an analogue of quantum white noise but it acts in a Fock space with indefinite metric. Quantum white noise describes the leading term in the stochastic limit approximation to quantum dynamics while quantum multipole noise describes corrections to the leading term. We obtain and study generalized q...

متن کاملWhite Noise Calculus and Hamiltonian of a Quantum Stochastic Process
Abstract. A white noise quantum stochastic calculus is developped using classical measure theory as mathematical tool. Wick’s and Ito’s theorems have been established. The simplest quantum stochastic differential equation has been solved, unicity and the conditions for unitarity have been proven. The Hamiltonian of the associated one parameter strongly continuous group has been calculated expli...
