Transient Lindblad Dynamics in Rydberg Atom RF Detectors H/F
Sujet de stage
JOIN US, TO DO WHAT?
Contribute to technological innovation for clean and safe energy, health and well-being, sustainable transportation, information and communications, space exploration, safety and security: that is the mission of CEA - Leti.
Rydberg-atom sensors exploit the extreme electric‑dipole moments of highly excited alkali atoms to transduce micro radio‑frequency fields into measurable optical signals. While the community has established sensitivities for continuous‑wave interrogation, the practical deployment of these devices in telecommunications, spectrum‑monitoring, and radar systems demands rapid, broadband response to transient Radio Frequency (RF) bursts that can last only a few nanoseconds. Accurately predicting such short‑pulse dynamics requires solving the open‑system Lindblad master equation in the time domain.

Description de l'offre
Join us for an internship!
CEA Tech Corporate from CEA Tech on Vimeo.
As an intern at CEA, you will have the opportunity to work in a world-renowned research environment. Our teams are made up of passionate and dedicated experts, offering a framework conducive to learning and collaboration. You will have access to state-of-the-art equipment and first-rate research resources to carry out your assignments.
YOUR ASSIGNMENTS:
The internship will develop and implement scalable, high‑performance algorithms for transient Lindblad dynamics tailored to the multi‑level Rydberg manifolds relevant to RF detection. The goal is to produce a validated simulation framework that captures the full time‑dependent response of the atomic ensemble to nanosecond‑scale RF pulses and quantifies detection limits and bandwidth.
Profil du candidat
What do we expect from you?
- Hold a strong background in electromagnetism and atomic physics
- Has experience in open‑system dynamics and the Lindblad formalism
- Proficiency in numerical methods and programming
- Prior knowledges to Rydberg‑atom experiments, RF field sensing, or related quantum‑sensor technologies will be advantageous
We offer:
An internship in the heart of the Grenoble metropolitan area, easily accessible via the CEA's soft mobility initiatives.
A unique research environment dedicated to topics with high societal impact.
Experience in a cutting-edge field of innovation with strong industrial development potential.
Training to strengthen your skills or acquire new ones in embedded electronics, information technology, telecommunications, and/or cybersecurity.
In accordance with the CEA's commitments to the integration of people with disabilities, this job is open to all. The CEA offers accommodations and/or organizational possibilities for the inclusion of workers with disabilities.
