Visiting Research Fellow in the energetics of near-term quantum computers

About the Centre for Quantum Technologies (CQT)

The Centre for Quantum Technologies (CQT) in Singapore brings together physicists, computer scientists and engineers to do basic research on quantum physics and to build devices based on quantum phenomena. Experts in this new discipline of quantum technologies are applying their discoveries in computing, communications, and sensing.
CQT is hosted by the National University of Singapore. The Centre also has staff at the Agency for Science, Technology and Research, Nanyang Technological University, Singapore, and the Singapore University of Technology and Design. With some 200 staff and students, it offers a friendly and international work environment

Job Description

A post-doctoral position is open in the group of Alexia Auffèves (MajuLab, CQT, Singapore), as part of the project HQI funded by the French Quantum Strategy. The fellow will explore the physical resource cost of near term quantum processors and study the conditions for energetic advantages of quantum nature. Doing so, the post-doc will contribute to build methodologies and bring answers to the emerging research line of the Quantum Energy Initiative, which aims at studying the energy cost of quantum technologies.  An important objective of the QEI is to develop an understanding of the conditions for an energetic advantage of quantum nature, by which a computation performed on a quantum processor would consume less energy than with a classical processor.

The post-doc will develop an understanding of the resource cost of typical algorithms executed on near term quantum computers. The exploration can hold on finding the ground state of small molecules, or of the Heisenberg Hamiltonian. The study will involve:

• The impact of the target performance on the resource cost, both without noise and with a noise with a fixed rate. Here we shall first consider the algorithmic resource cost (number of gates, of measurements...) and possibly relate it to an energetic cost;
• The impact of the noise on the resource cost for a fixed target performance;
• The comparison with a classical reference point to study the conditions of a resource quantum advantage;
• The possibility to perform reverse-engineering and to deduce constraints on the hardware from the condition to observe a resource quantum advantage;
• The possibility to propose experiments to measure the resource/energy cost.

Job Requirements

• PhD in quantum physics or computer science, with a focus on quantum computing and curiosity for full-stack quantum computing. 1 to 2 years of post-doctoral experience will be a strong plus;
• Strong skills in programming languages python and qutip, experience with qiskit and other cloud based platforms, resource estimators, classical high-performance computing are plus;
• Excellent analytical, organizational, and communication skills;
• Capacity to develop and nurture crossed-disciplinary networks;
• Proven track record of published research and presentations in relevant fields;
• Creativity and ability to think out of the box;
• Capacity to develop strategies of influence in complex international environments
