A three-year senior post-doctoral position is available in the group of Alexia Auffèves (CNRS-MajuLab-CQT, Singapore), as part of the project BACQ funded by the French Quantum Strategy. The post-doc will build standards of energetic efficiencies for full-stack quantum processors and study the conditions for energetic advantages of quantum nature in a systematic way. She/he will develop an open numerical platform to estimate these efficiencies, providing new optimizing methods of research and development for industrial end-users and new figures of merit for quantum benchmarking. She/he will work in close collaboration with experts of both quantum hardware and quantum software from academia and industry, and play a leading role in the writing of standards in the newly created IEEE working group 3329 "Quantum Energy Initiative".

About Us- The quantum energy team |QET> is a non-local theoretical research team based in Singapore and in Grenoble [1]. Our skills are quantum energetics, quantum optics, and quantum transport, that we apply to explore foundational and technological open questions in close collaboration with top level experimental groups worldwide. We are leaders in the development and application of a holistic methodology to estimate and optimize the energy consumed by the full stack of a quantum computer. We are co-founders of the Quantum Energy Initiative [2], a worldwide community of experts aiming to provide the community with objective figures of merit to model and optimize the energetic efficiency of quantum technologies. A. Auffèves chairs the IEEE working group "Quantum Energy Initiative" devoted to the development of standards of energetic efficiencies of quantum computers [3].

French Quantum Strategy - The job offer is part of the project BACQ "Application-oriented benchmarks for quantum computing" funded by the French quantum strategy through the programme France 2030. BACQ aims to developing an objective, long-lasting, widely shared measurement instrument, to serve as a common reference, for the evaluation of the quantum computing practical performance, by considering benchmarks close to real applications, meaningful for industrial end-users. By allowing the overall comparison between different quantum computing solutions and with classical computers, BACQ will contribute to measure the progress towards a practical quantum advantage. The consortium gathers the CNRS, the CEA, Eviden, the LNE, Teratec, and Thales as coordinator. The project involves numerous collaborations with French quantum startups which will eventually measure the proposed energetic efficiencies on their processors.

Spirit of the job - The job comprises intertwined scientific and strategic challenges.

Scientific challenges: Defining, measuring and optimizing energetic efficiencies for quantum computers is by essence an interdisciplinary task [4,5]. Energetic efficiencies are ratios between metrics of performance and energetic costs. On the one hand, metrics of performance characterize well-defined computational tasks, and result from the degree of control over noise attained at the quantum level. Energetic costs, on the other hand, are set at the macroscopic level by enabling technologies: cryogenics, microwaves, control electronics...The interdependence between the macroscopic and the quantum levels is non-trivial: systematic explorations require to develop holistic methodologies, as called in the quantum energy initiative [2] and proposed in [5]. The post-doc will play a central role in the development, documentation and execution of these methodologies, in close collaboration with experts of the field. This includes: the build-up of standards of energetic efficiencies for full-stack quantum processors executing well-defined tasks, the study of the conditions for energetic advantages of quantum nature in a systematic way, the development of an open numerical platform to estimate these efficiencies.

Strategic challenges: in the emerging area of quantum computing, developing documented standards of energetic efficiency is mandatory for strategic, economic and societal reasons. The post-doctoral fellow will strongly contribute to the elaboration of such standards within the IEEE 3329 working group "quantum energy initiative" [3] chaired by A. Auffèves and gathering a crossed disciplinary group of experts.

Working environment- The post-doc will be hosted in the group of Alexia Auffèves in MajuLab [6], CQT [7], Singapore. Beyond the BACQ consortium, she/he will be involved in a network of collaborations with leading experimental groups holding on fundamental features of quantum energetics in various hardware (photons, spins, superconducting qubits) and on fundamental thermodynamics of information. She/he will integrate the vibrant environment of the Centre for Quantum Technologies, a long-standing powerhouse of quantum. She/he will engage in the fast-paced Singaporean ecosystem, a multicultural hub and Asian leader in deep tech.
