Postdoc Position in Experimental Quantum Engineering (EQE) Group
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
We seek a postdoctoral researcher to contribute to a new experimental platform based on dual‑typetweezer 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
More information about the project and the group can be found on our website.
Profile
* PhD in physics or a related field
* Strong background in experimental AMO physics or quantum optics
* Experience with cold atoms, optical tweezers, lasers, or quantum control techniques is highly desirable
* Strong interest in neutral‑atom quantum technologies and many‑body quantum physics
* Ability to work both independently and collaboratively
* Good communication skills in English (German is a plus)
We offer
* A highly creative and collaborative research environment
* Freedom to develop independent research directions
* Access to world‑class infrastructure at ETH Zurich and PSI
* Opportunities for interdisciplinary and international collaborations
