Postdoc Position in Experimental Quantum Engineering (EQE) Group, Villigen

The Experimental Quantum Engineering (EQE) group at ETH Zurich and the Paul Scherrer Institute (PSI) invites applications for a highly motivated postdoctoral researcher to work at the interface of quantum optics, quantum information science and quantum many-body physics.

Led by Prof. Wenchao Xu, the EQE group develops programmable quantum systems based on neutral atoms and Rydberg interactions to advance both fundamental quantum science and next-generation quantum technologies. Our research combines atomic physics, quantum control, and scalable architectures for fault‑tolerant quantum computation, hybrid quantum simulation, and quantum‑enhanced sensing.

Project background Our group addresses key challenges in quantum science by building and exploiting hybrid quantum systems consisting of individually controlled atoms and atomic ensembles.

Current research directions include:

Demonstrating scalable architectures for fault‑tolerant quantum information processing, featuring reconfigurable local control, rapid quantum non‑demolition readout, and fast error‑syndrome extraction

Developing strong atom–light interfaces to enable quantum interconnects and modular quantum systems

Investigating non‑equilibrium quantum many‑body dynamics and quantum information dynamics in programmable atom arrays

Job description We seek a postdoctoral researcher to contribute to a new experimental platform based on dual‑type tweezer atom arrays.

The project aims to demonstrate the unique advantages for:

Reconfigurable local quantum control

Rapid, non‑demolition state detection of both single‑ and multi‑qubit states

Novel phenomena in quantum dynamics arising from the interplay with measurement

These capabilities enable new routes toward fault‑tolerant quantum computation and open exciting opportunities for exploring frontier problems in quantum information dynamics.

The successful candidate will:

Design, build, and operate state‑of‑the‑art neutral‑atom experiments

Demonstrate novel quantum control and measurement protocols

Lead research projects and mentor students

Collaborate closely with researchers at ETH Zurich, PSI, and international partners
