Research Fellow on the Modeling of Fundamental Processes with Optical Non-Linearities (NGAP Project)

NGAP Project is looking for a Research Fellow on the Modeling of Fundamental Processes with Optical Non-Linearities


N-GAP: Nanophotonic GAtes with exciton-Polaritons

One of the main goals in the field of quantum technologies is to achieve quantum computing.

Many technologies and platforms have been suggested to build a quantum computer, including ions, atoms, electrons, and superconducting materials. Among these options, all-integrated photonic platforms that allow creating complex circuitry with a small footprint are very promising.

In N-GAP we will explore and exploit a hybrid state of light and matter, the excitonic polariton, to create a platform for quantum computing. Exciton polaritons, which emerge from the strong-coupling of an exciton and a photon, exhibit Kerr nonlinearities typically three orders of magnitude stronger than that found in standard photonic nonlinear crystals.

The main objective of N-GAP is to further enhance the nonlinearity of the polariton systems to achieve the first experimental realisation of a deterministic CNOT gate based on polariton systems, which is the essential building block of a quantum computer.

Scientific objectives- The post-doc will investigate the potential of optical non-linearities to perform energy-efficient quantum computing, amplification and measurements. She/he will build analytical models describing the joint dynamics of optical non-linearities and propagating pulses of light in the quantum regime of interaction. A fully Hamiltonian dynamics is targeted, unlocking access to light-matter entangled states and the possibility to explore various optimization regimes for the quantum processes at play. The post-doc will realize accurate energy balances between light and matter, and estimate energy costs of fundamental quantum processes, e.g. quantum gates and amplification.

Working environment- The research fellow will be hosted in the group of Alexia Auffèves in MajuLab, CQT, Singapore. The group is pioneer in the modelling of interactions between quantum emitters and propagating pulses of light. She/he will be involved in a network of collaborations with leading experimental groups in quantum computing with light. 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.


  • PhD in quantum physics, with a focus on quantum optics and quantum open systems. Past work in the foundations of quantum measurement will be a strong plus.
  • Excellent analytical, organizational, and communication skills.
  • Proven track record of published research and presentations in relevant fields.
  • A solid knowledge of written and spoken English is mandatory.

We expect good interpersonal skills, the ability to thrive in a diverse, multidisciplinary environment, and the ability to present work at international conferences.


Salary range: SGD6,900 to SGD9,000 (depending on suitability and experience)
