Postdoc on Fundamental Phenomena in Microcavities Close to The Giant Nonlinear Regime (NGAP Project) (NGAP Project)

Job offer posted on 11 July 2024.

NGAP Project is looking for a Postdoc Researcher to conduct and analyse experiments aimed at understanding the physics at play in highly nonlinear polaritonic semiconductor microcavities.

N-GAP: Nanophotonic GAtes with exciton-Polaritons

Quantum computing is one of the key promises of quantum technologies. Many quantum degrees of freedom have been envisaged to realize a quantum computer, including ions, atoms, electrons, and superconducting materials. Among these options, integrated photonic platforms that allow creating ultrafast complex circuitry with a small footprint are very promising.

In the N-GAP project, our goal is to explore whether exciton-polaritons, a hybrid state of light and exciton, can be exploited as a quantum degree of freedom for quantum computing. exciton-polaritons exhibit a unique feature in this context: a giant Kerr nonlinearity, typically three orders of magnitude stronger than that found in standard photonic nonlinear crystals. The main objective of N-GAP is to push this nonlinearity closer and potentially deep into the quantum regime, to achieve the first experimental realisation of a deterministic CNOT gate based on polariton systems.

The candidate will perform experimental micro-spectroscopy in cryogenic cooled polaritonic microcavities under resonant excitations. He/she will investigate the nature of the many-body quantum states resulting from the system giant nonlinearity. To do so, he/she will probe its elementary excitations, in different steady-state and transient (quench) situations. For this purpose, he/she will develop spectroscopy techniques inspired from Brillouin spectroscopy with imaging capability.

He/she will analyze the experiments and participate in the theoretical developments, and comparison with the experiments. The appointee will work in a highly collaborative environment and must feel comfortable in daily interactions with collaborators, live and remotely.

The candidate should have a solid academic track-record, and a previous experience in experimental physics on connected topics such as: Quantum optics, quantum properties of ultracold atomic vapours, optical spectroscopy of quantum systems.

The appointee will join Majulab at CQT (Singapore) under the supervision of Dr. Maxime Richard (Majulab & CQT affiliated, Singapore). He/She will carry out experimental work in CQT at Singapore.

The applicant should submit a detailed CV. Positions will initially be offered for 1 year, with possible extension for at least one more year. The start date is flexible. If shortlisted, applicants should also arrange for two letters of reference to be sent directly to the supervisors.

Salary range: SGD6,500 to SGD9,000 (depending on suitability and experience)

Workplace address: The applicant will be a CNRS@CREATE appointee (CREATE Campus, CREATE Tower, 1 Create Way #08-01 Singapore 138602), and work at the Centre for Quantum Technologies (National University of Singapore) and Majulab, 3 Science drive 2, 117543, Singapore.
