PhD Positions in Quantum Networking with Superconducting Circuits, ETH Zurich (Wallraff Lab)
Job Description
These PhD positions in quantum networking at ETH Zurich are in Andreas Wallraff’s Quantum Device Lab. You will build and run a two-node network of superconducting qubits. The lab reviews applications as they arrive, until the posts are filled.
At a glance
- Position: Doctoral students, 100%, fixed term
- Where: Quantum Device Lab, Department of Physics, ETH Zurich, Switzerland
- Lab head: Prof. Andreas Wallraff
- Pay: Not stated in the ad
- Apply: open until filled (re-checked 27 November 2026)
About the quantum networking PhD project
- Join the team that runs a two-node quantum network: two dilution refrigerators 30 metres apart, linked by a cryogenic microwave link
- Expand the platform through chip fabrication, packaging, networking protocols and distributed control
- Implement quantum networking protocols on multi-qubit superconducting chips
- Design electronics and mechanical parts, build microwave set-ups and fabricate chips
- Design experiments and explore uses such as distributed quantum computing and non-local sensing
The platform makes remote entanglement by sending microwave photons across the link. It has already run loophole-free Bell tests and randomness amplification. Next steps include loss-tolerant photonic state transfer, distributed error correction and blind quantum computing.
Why this role matters
Linking quantum computers is the next step after building them. This lab runs one of the few working superconducting quantum networks in the world. A PhD here trains you on real network hardware.
What ETH Zurich is looking for
- A strong interest in experimental quantum information, with a focus on remote and non-local uses
- Experience and a record in one or more of: quantum information hardware, experimental quantum optics and cavity QED, micro- and nanofabrication, quantum networking, mesoscopic or low-temperature physics
- Or experience in microwave electronics, digital electronics, FPGAs, instrumentation, drivers or software
- Commitment to a career in research, development or education
Pay and location
The ad does not state pay, contract length or start date. The posts are full time (100%) and fixed term, in Zurich. The project is part of the Swiss Quantum Science and Technology network and the ETH Quantum Center.
How to apply
Apply through the official ETH Zurich job posting. ETH Zurich’s posting does not give a closing date, so the role is open until filled; ResearchJobs.in will re-check this listing on 27 November 2026. Apply only through ETH’s online portal, with a CV, a publication list, a research statement, Bachelor’s and Master’s transcripts, and three referees. Questions go to wallraff.office@phys.ethz.ch, but do not send applications there. Check the posting for location and work-authorisation details before you apply.

How to prepare for this application
- Revise remote entanglement: how a shared photon links two qubits, and what limits fidelity and rate.
- Read the lab's Bell test work: know why a 30-metre cryogenic link made a loophole-free test possible.
- Show hands-on skill: cleanroom, microwave set-ups, FPGA code or lab software you built yourself.
- Write a sharp research statement: your background, motivation and skills, as the ad asks.
- Arrange a letter: name three referees, and ask at least one to email wallraff.office@phys.ethz.ch directly.
