Postdoctoral position (M/F) Theory of Hybrid Quantum Systems – Control of Magnon Dissipation via Feedback

Job Description

Missions

Scientific Context:
Over the past few decades, remarkable progress has been made toward constructing functional quantum processors. However, to build fully capable quantum computers and networks, a wide range of complementary quantum technologies will be required. These include short- and long-timescale quantum memories (equivalent to the RAM and hard drives of today's computers), as well as quantum wavelength transducers to enable the transfer of quantum information between subsystems. To achieve these goals, research into hybrid quantum systems—which couple two or more subsystems to exploit the emergent properties of these interactions—is essential.
One promising hybrid quantum system is cavity magnomechanics, where magnons serve as intermediaries between photons and phonons. Magnons are already used in classical applications, such as narrowband filters in GHz electronics. Unfortunately, for quantum applications, the dissipation rate of magnons limits the performance of such hybrid systems. This project therefore aims to develop theoretical and experimental tools to control the magnon dissipation rate using feedback protocols, thereby enabling the continued development, deployment, and use of quantum computing hardware, in alignment with national quantum strategies, such as Canada's National Quantum Strategy.
The recruited candidate will participate in a Franco-Canadian collaboration focused on the study and optimization of dissipation in magnonic systems.

Activity

Develop theoretical models to describe and optimize the control of magnon dissipation via feedback.
Collaborate with the experimental team to validate these models and propose innovative protocols.
Publish results in high-impact scientific journals and present advancements at international conferences.
Actively contribute to team meetings and scientific discussions within the laboratory.

Your Profil

Skills

PhD in theoretical physics, quantum physics, or a related field.
Proven experience in hybrid quantum systems, optomechanics, magnonics, or quantum control theory.
Proficiency in theoretical modeling tools (e.g., effective Hamiltonians, master equations, feedback methods).
Ability to work in a team and interact effectively with experimentalists.
Excellent written and oral English (scientific level).
Autonomy, rigor, and creativity.

Your Work Environment

Work Environment:
The recruited candidate will join a dynamic team within a laboratory specializing in quantum physics and hybrid systems, with access to high-performance computing infrastructure and an international collaborative network. The position will be based at the Laboratoire Ondes et Matière d'Aquitaine (LOMA), Bordeaux, France.
