Is the Job related to staff position within a Research Infrastructure?: NoOffer Description
The Laboratory of Photonics, Electronics, and Quantum Engineering (PHELIQS) is a joint research unit of the CEA and the Université Grenoble Alpes (UGA). Organized into five teams, PHELIQS includes about 60 permanent staff members (researchers, teacher-researchers, technical and administrative personnel) and hosts around 35 PhD students and 15 postdoctoral researchers.
PHELIQS conducts fundamental research in the fields of nanophysics and condensed matter physics, mainly upstream of information and communication technologies. The research at PHELIQS aims in particular at understanding and controlling original physical effects, generally of quantum origin, that appear in solid-state systems of reduced dimensionality or nanometric size, as well as in materials with strong electronic correlations. The goal is to provide innovative solutions to major challenges in photonics and nanoelectronics, notably the development of components and systems for quantum information processing.
The PhD will develop in several directions, all of them being entirely origina:
- We will develop techniques to tackle the dynamics of these systems both in imaginary and real time. The latter will form a quantum inspired quantum computer emulator that should be able to tackle large systems of >100 qubits with 2D connectivity or higher. Initial applications will be on qubit systems to challenge quantum advantage claims. When the technique is mature, this will be used to compute quantities of interest, e.g. the spectral density of strongly correlated models, as measured in ARPES.
- The mathematics of the approach will require a lot of innovative developments too. In the only published article [Srdinsek2025], the sole structure of the tensor networks that could be “salvaged” was the canonical form that provided the ability to dynamically compress/decompress. During this PhD, we will develop more; we have unpublished results showing that linear combinations and operations on the ansatz can also be included. This will allow us to perform the ground state search and the dynamics without resorting to the hazardous noisy non-convex optimization.
- The scope of (new) applications is very large. Initially we will focus on qubit systems but in a second step we will consider Hubbard like models for strongly correlated materials. If time allows, as mentioned before, there is also the possibility to address LLM and chemistry with very similar approaches
