Position: Postdoctoral Researchers for 3-year projects on quantum networks and quantum sensing 100%
Location: Zürich

The Optical Nanomaterial Group in the Physics Department at ETH Zurich is looking for two Postdoctoral Researchers for 3‑year projects on quantum networks and quantum sensing.

Job description

Photonic integrated circuits promise advanced functionality for applications such as quantum information processing and precision sensing. Thin film lithium niobate (TFLN) is a maturing photonics platform that can integrate frequency conversion, quantum light sources and high‑speed electro‑optic modulation on a single device.

In the Optical Nanomaterial Group, we specialise in the nanofabrication and optical characterization of TFLN photonic circuits for applications in nonlinear optics, quantum communications and quantum sensing. The open positions will work on (1) TFLN circuits for quantum networks and (2) TFLN circuits for quantum sensing – both projects are 3 years long.

Responsibilities

Quantum networks involve entangling distant quantum memories, however many of the leading quantum memories operate at visible wavelengths. We aim to use TFLN photonics for sources of non‑degenerate entangled photon‑pairs with one photon at the quantum memory wavelength and the other photon in the telecom band for long‑distance transmission over optical fibre. This position is part of a Switzerland‑wide consortium on quantum networks.

Quantum light can enhance sensing through phase estimation and absorption measurements with undetected photons. We aim to use TFLN photonics for generating squeezed vacuum for gas sensing applications, where periodically poled wave guides and photon‑number resolution detection provide a quantum advantage. This position is part of a QuantERA project with Imperial College London, the University of Oxford and ICFO.

Profile

Postdoctoral Researchers with experience in integrated photonics, nonlinear optics, quantum photonics, quantum information and spontaneous parametric down‑conversion.
Work on background theory, simulation, design, some aspects of nanofabrication, and characterisation of photonic circuits, and perform quantum information experiments.
Collaborate with other Postdocs and PhD students in nanofabrication and optical characterisation, and interact with the group through regular project and group meetings.

Target start dates for these positions are between October 2026 and January 2027.
