Gradients, parallelism, and variance of quantum estimates
Francesco Preti, Michael Schilling, József Zsolt Bernád +3
Computation of observables and their gradients on near-term quantum hardware is a central aspect of any quantum algorithm. In this work, we first review standard approaches to the…
An exact Markovian decoherence dynamics of two interacting harmonic oscillators coupled to a bosonic heat bath
Gábor Homa, Dávid Hamar, József Zsolt Bernád +2
We present an exact analytical solution of the Hu-Paz-Zhang master equation in a precise Markovian limit for a system of two harmonically coupled harmonic oscillators interacting w…
Optomechanical systems with linear and quadratic position couplings: Dynamics and optimal estimation
Yaqing Xy Wang, Claudio Sanavio, József Zsolt Bernád
We study the dynamics of an optomechanical system consisting of a single-mode optical field coupled to a mechanical oscillator, where the nonlinear interaction includes both linear…
Dynamical control of quantum systems in the context of mean ergodic theorems
J. Z. Bernád
Equidistant and non-equidistant single pulse "bang-bang" dynamical controls are investigated in the context of mean ergodic theorems. We show the requirements in which the limit of…
