Action principle for continuous quantum measurement [PDF]
, 2013 We present a stochastic path integral formalism for continuous quantum measurement that enables the analysis of rare events using action methods. By doubling the quantum state space to a canonical phase space, we can write the joint probability density ...

Fluctuation theorems for quantum master equations [PDF]
, 2006 A quantum fluctuation theorem for a driven quantum subsystem interacting with its environment is derived based solely on the assumption that its reduced density matrix obeys a closed evolution equation i.e. a quantum master equation (QME).

Random non-Hermitian action theory for stochastic quantum dynamics: from canonical to path integral quantization [PDF]
Journal of Physics A: Mathematical and TheoreticalWe develop a theory of random non-Hermitian action that, after quantization, describes the stochastic nonlinear dynamics of quantum states in Hilbert space.

On stochastic quantisation of supersymmetric theories
Physics Letters B, 2019 We explain how stochastic TQFT supersymmetry can be made compatible with space supersymmetry. Taking the case of N=2 supersymmetric quantum mechanics, (the proof would be the same for the Wess–Zumino model), we determine the kernels that ensure the ...

Multi-point Gaussian States, Quadratic–Exponential Cost Functionals, and Large Deviations Estimates for Linear Quantum Stochastic Systems [PDF]
Applied Mathematics and Optimization, 2017 This paper is concerned with risk-sensitive performance analysis for linear quantum stochastic systems interacting with external bosonic fields. We consider a cost functional in the form of the exponential moment of the integral of a quadratic polynomial

Fast-Converging Simulated Annealing for Ising Models Based on Integral Stochastic Computing
IEEE Transactions on Neural Networks and Learning Systems, 2022 Probabilistic bits (p-bits) have recently been presented as a spin (basic computing element) for the simulated annealing (SA) of Ising models. In this brief, we introduce fast-converging SA based on p-bits designed using integral stochastic computing ...

(Non) equilibrium dynamics: a (broken) symmetry of the Keldysh generating functional
SciPost Physics, 2018 We unveil the universal (model-independent) symmetry satisfied by Schwinger-Keldysh quantum field theories whenever they describe equilibrium dynamics.
