Emergent gravity from the correlation of spin- systems coupled with a scalar field
Quentin Ansel
This paper introduces several ideas of emergent gravity, which come from a system similar to an ensemble of quantum spin- particles. To derive a physically relevant t…
Quantum States Seen by a Probe: Partial Trace Over a Region of Space
Quentin Ansel
The partial trace operation is usually considered in composite quantum systems, to reduce the state on a single subsystem. This operation has a key role in the decoherence effect a…
Introduction to Theoretical and Experimental aspects of Quantum Optimal Control
Q. Ansel, E. Dionis, F. Arrouas +4
Quantum optimal control is a set of methods for designing time-varying electromagnetic fields to perform operations in quantum technologies. This tutorial paper introduces the basi…
Calculus of Variation and Path-Integrals with Non-Linear Generalized Functions
Quentin Ansel
The calculus of variation and the construction of path integrals is revisited within the framework of non-linear generalized functions. This allows us to make a rigorous analysis o…
Loop quantum gravity with optimal control path integral, and application to black hole tunneling
Quentin Ansel
This paper presents a novel path integral formalism for Einstein's theory of gravitation from the viewpoint of optimal control theory. Despite its close relation to the well-known…
A Model of Spinfoam Coupled with an Environment
Quentin Ansel
In this paper, an open quantum system theory for spinfoams is developed. This new formalism aims at deriving an effective Lindblad equation to compute the reduced dynamics of a qua…
Selective and Robust Time-Optimal Rotations of Spin Systems
Quentin Ansel, Steffen J. Glaser, Dominique Sugny
We study the selective and robust time-optimal rotation control of several spin-1/2 particles with different offset terms. For that purpose, the Pontryagin Maximum Principle is app…
