This PhD project will investigate a new route towards robust quantum bits based on Andreev bound states in hybrid semiconductor-superconductor devices. Andreev states offer a highly tunable microscopic quantum degree of freedom, but their coherence is typically limited by sensitivity to charge, flux and magnetic noise. The goal of the project is to overcome this limitation by embedding Andreev-based qubits in engineered superconducting circuits, so that the circuit environment provides hardware-level protection while preserving fast and flexible control.
The successful candidate will develop theoretical and numerical models of hybrid Andreev-circuit devices, compute spectra and transition matrix elements, analyse noise sensitivity, and simulate decoherence using open-quantum-system methods. The project will also explore optimization strategies, including machine-learning-based approaches, to identify device parameters that maximize robustness and qubit performance.
The position offers training at the interface of condensed matter theory, superconducting quantum circuits, mesoscopic physics and quantum technologies. The expected outcome is a set of design principles for protected Andreev qubits, contributing to the development of scalable and experimentally realistic quantum hardware.
