Postdoctoral Research Scientist in quantum optics and networking with superconducting circuits

 The Quantum Device Laboratory at ETH Zurich studies quantum information science with superconducting circuits. A team led by Andreas Wallraff and Jean-Claude Besse focuses on studying the interaction of transmon qubits with microwave photons.

Project background

The lab's work on fundamental phenomena in quantum optics investigates the interaction of light with matter at the quantum level, while its research on quantum networks focuses on the development of technologies that enable the efficient transmission of quantum information over long distances including applications of non-locality. Recently, we have realized milestone experiments on single photon detection, the realization of a universal quantum gate set for microwave photonic qubits, and the deterministic entanglement of remote qubits.

Job description

You will perform collaborative research towards the realization of distributed, or measurement-based quantum computing, realize device-independent protocols such as quantum key distribution or randomness amplification, perform error correction on quantum channels, or work on the generation and study of highly entangled states of microwave photons. You will both benefit from the expertise developed at the Quantum Device Laboratory and expand the state of the art in this field of research.

Your profile

  • You have a strong and documented interest in experimental realizations of quantum information processing systems and a dedication to pursuing a successful career in research, development, or education, either in academia or industry.
  • Ideally, you have experience and a proven record in multiple of the following topics:
    • Quantum information processing and its implementations (ideally with superconducting circuits, alternatively also with quantum dots, ion traps, NMR, photonics, …)
    • Experimental quantum optics or atomic physics (cavity quantum electrodynamics)
    • Fabrication and characterization of micro- and nano-electronic devices (lithography and deposition techniques)
    • Mesoscopic solid state physics, low-temperature physics, transport measurements at dilution refrigerator temperatures
    • Microwave electronics, digital electronics, FPGAs, measurement instrumentation
    • Programming experience, e.g. in Python (or similar)

We are looking forward to receive your online application including:

  • a cover letter
  • your detailed curriculum vitae
  • a complete list of your publications
  • a research statement, containing a short description of your background, motivation, and skills
  • copies of bachelor, master, and PhD theses (as available, with grades available)
  • three contacts available to provide letters of reference
  • at least one reference letter to be sent directly by email to

Please note that we exclusively accept applications submitted through our online application portal. Applications via email or postal services will not be considered.
