Missions

The postdoctoral researcher will be part of the theory pole and responsible for developing quantum algorithms for complex many-body systems and studying quantum information-related aspects. He/she will work under the supervision of Denis Lacroix. Specifically, the research project's goal will be to develop new methods for simulating complex quantum systems using quantum computers and to compare these methods with state-of-the-art theories standardly used in classical computers, like matrix-product-states or the phase-space approach proposed by our team recently. All facets of nonequilibrium simulations will be studied, including efficient quantum algorithms for real-time and imaginary-time algorithms to access ground-state properties, excited state, and/or far-from-equilibrium properties. Another aspect is the study of entanglement properties through von Neumann entropy and Quantum Magic.

Activités

The post-doctoral fellow will be in charge of developing new algorithms for the quantum simulation of complex systems. He or she shall contribute to activities such as
• Quantum Algorithms development and associated numerical implementation in pilot applications. Anticipated applications will be of interest for nuclear physics, neutrinos, and condensed matter.
• More in-depth investigations on entanglement growth in these systems are needed. This includes the development of innovative tools to measure entanglement.
• participation in the coordination of the team working on quantum computers. This includes the participation in projects of the PhD students and eventual supervision of Master's internships.

Compétences

Candidates must hold a doctorate in Many-Body Physics or Quantum computing fields and have proven research skills evidenced by at least one publication relating to the subject or activities of the project. Candidates must have a very positive attitude when working in a team. Finally, a good level of spoken or written English is a requirement.

Contexte de travail

IJCLAB bases its recruitment policy on promoting equality, diversity, and inclusion. Essential values allow the professional development of agents, who are real actors in a collective success, but also the development of the laboratory itself.
The Irène Joliot-Curie Physics Laboratory of 2 Infinities (IJCLab) is a UMR under the supervision of the CNRS (IN2P3), the University of Paris-Saclay and the University of Paris is located on the campus of the University of Paris -Saclay in Orsay. The laboratory is located on the campus of the Université Paris-Sud, Université Paris-Saclay in Orsay. The campus is located 20 km south of Paris and easily accessible by RER in 35 minutes.
IJCLab was born in 2020 from the merger of five units (CSNSM, IMNC, IPN, LAL, LPT). The staff is made up of nearly 560 permanent (340 engineers, technicians, and administrators, and 220 researchers and teacher-researchers) and approximately 200 non-permanent, including 120 doctoral students. The research themes of the laboratory are nuclear physics, high energy physics, theoretical physics, astroparticles, astrophysics and cosmology, particle accelerators, energy, and the environment and health. IJCLab has significant technical capacities (around 280 IT) in all the major fields required to design, develop/implement the experimental devices necessary for its scientific activity, as well as the design, development, and use of instruments.

The researcher will work on the theory pole of IJCLab and, more specifically, in the nuclear theory team. The Theory Pole has activities including mathematics, statistical physics, nuclear physics, astrophysics, astroparticles, particle physics and cosmology.
The group includes around 70 physicists (permanent researchers, post-docs, and doctoral students).

Le poste se situe dans un secteur relevant de la protection du potentiel scientifique et technique (PPST), et nécessite donc, conformément à la réglementation, que votre arrivée soit autorisée par l'autorité compétente du MESR.

Contraintes et risques

Short periods of travel within France and abroad should be expected, in particular, to participate in workshops and conferences related to the researcher's research activity.
