Postdoc in bosonic quantum error correction with superconducting circuits

Deadline: August 31st, 2022 Location: Villigen, Switzerland As part of the ERC replacement grant scheme of the SNF, the Bosonic quantum information group at the Paul Scherrer Institute is looking for a postdoctoral researcher. The position will start after November 2022. In our research, we develop new ways to store and manipulate quantum information in nonlinear superconducting oscillators. A key element of our work is to make use of the many energy levels present in these oscillators to encode qubits that are intrinsically protected against errors. Part of our work is to devise and implement new parametric processes in nonlinear quantum oscillators in order to stabilize the highly excited basis states of these qubits. Our goal is to explore both the promise of this approach for quantum computation and simulation, as well as its fundamental aspects in the context of out-of-equilibrium physics. We are currently looking for a motivated researcher with experience or interest in circuit QED, quantum information processing, and nonlinear quantum optics. Over the course of the project, she/he will use a wide range of experimental skills including: • Cryogenics and operation of dilution refrigerators • Microwave circuit design • Nanofabrication and characterization (lithography, growth and deposition, SEM, AFM, etc.) • Experimental control and data analysis software • Quantum measurement and control techniques In addition, the successful applicant will participate in the theoretical developments associated with the project and co-supervise Master’s and internship student projects. She/he should hold a PhD in a relevant field and have good English language skills. A solid background in quantum mechanics and prior experience in at least one of the techniques mentioned above are required for this position.

Interested candidates should send Alexander Grimm (alexander.grimm@psi.ch) a CV and briefly describe why you would like to work with us.
