Contexte et atouts du poste

The project NISQ2LSQ funded by the French Quantum Strategy aims to accelerate R&D efforts in the theory and design of hardware-efficient, fault-tolerant quantum codes, focusing on bosonic codes and quantum low-density parity codes (LDPC). On the hardware side, the targeted platforms are superconducting and photonic qubits, as well as neutral atoms.

The Junior Research Leader will be hosted at Inria Paris, in the COSMIQ team which already has an expertise in the design and decoding of quantum LDPC codes. The position is open for a fixed-term contract of 3 years. The applicant can also be a young researcher, already hired on a permanent position and intending to pursue a research topic in line with the above theme. In this second case, the funding will be used to cover the hiring of PhD students and/or postdocs, collaborating with the young researcher.

Mission confiée

The Junior Research Leader will develop the theory of fault-tolerant quantum computing based on high-rate quantum codes, especially quantum LDPC codes. These codes are attracting a lot of attention because they offer a drastic overhead reduction for fault tolerance and recent experimental progress hints that they might be implementable sooner than initially anticipated.

In this context, a pressing issue is to understand how to perform fault-tolerant logical gates when the information is encoded in quantum LDPC codes. A challenge here is to be able to rigorously assess the performance of various schemes, and this requires the development of tools for the simulation of such procedures. For this, it will be crucial to interact with experimental groups working on various hardware approaches (neutral atoms, photonic qubits) in order to study realistic noise models, and adapt the fault-tolerant techniques to the constraints of the relevant hardware platforms.

 

The Junior Research Leader is expected to build a team to address these questions. They will be encouraged to develop collaborations with various experimental groups in the Ile-de-France area, and in particular with the quantum startups

Principales activités

The Junior Research Leader will conduct research on the topic described above.

Compétences
