PhD position in bosonic quantum error correction with superconducting circuits (experiment)
Deadline: April 30th, 2025 (or until the position is filled)
Location: Villigen, Switzerland
The Bosonic Quantum Information group at the Paul Scherrer Institute is looking for a PhD student. The position will start in Q2/Q3 2025.
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 student with experience or interest in circuit QED, quantum information processing, and nonlinear quantum optics. Over the course of the project, she/he will acquire a wide range of experimental skills including:
• Cryogenics and operation of dilution refrigerators
• Microwave circuit design
• Nanofabrication and characterization (lithography, thin-film growth and deposition, SEM, AFM, etc.)
• Experimental control and data analysis software
• Quantum measurement and control techniques
In addition, the student will be encouraged to participate in the theoretical developments associated with the project and co-supervise Master’s and internship student projects. The successful candidate should have good English language skills and a solid background in quantum mechanics. Prior experience in any of the techniques mentioned above is considered a plus.
