Offer Description
General Scope: The project aims to advance hybrid superconductor–semiconductor technologies that have already proven powerful for superconducting qubits, quantum-limited amplifiers, and topological-quantum research. While today’s commonly used Josephson parametric amplifiers rely on conventional tunnel Josephson junctions, hybrid materials offer gate-tunability and potentially enhanced performance using graphene, two-dimensional electron gases, and semiconductor nanowires. To overcome limitations of conventional Josephson parametric amplifier designs, the team will design and characterize Josephson parametric amplifiers based on nanowire Josephson junctions. We will use superconductors with large superconducting gap, such as Sn or Ta, to make the Josephson parametric amplifiers compatible with magnetic-field operation, enabling integration with spin-qubit and topological-quantum platforms.
PhD Subject: The objective of the PhD project is to build a Josephson parametric amplifier that leverages the possibilities offered by InAs nanowire Josephson junctions. The PhD student will fabricate Josephson junctions using inclined InAs nanowires developed in Institut Néel by Moira Hocevar using molecular beam epitaxy. The deposition of the superconductor will either be done in situ or ex-situ in existing equipments.. The student will evaluate the quality of the superconductor thin films deposited on nanowires as well as the DC properties of the Josephson junctions using electrical transport at low temperature. Once optimized growth conditions are identified, they will be used for the fabrication of a functional amplifier. The Josephson parametric amplifier will be designed to operate in the GHz range, which is typical for its use in superconducting quantum computing. Measurement will be made in a dilution refrigerator to characterize the performances of the amplifier, such as gate tunability, noise temperature or resilience to magnetic fields. The possibility to generate non classical states of light (squeezed states) with such device will be explored.

Additional Information
Eligibility criteria
Applicants must hold a Master’s degree or an equivalent qualification by the application deadline and must not already hold a doctoral degree. Applicants must also comply with the MSCA mobility rule: they must not have resided or carried out their main activity (work, studies, etc.) in France for more than 12 months during the 36 months immediately preceding the application deadline. Applicants must not be current employees of the host laboratory. There are no nationality or age restrictions.
Selection process
Applications must be submitted through the QuanG2 online application platform by 7 September 2026 at 12:00 PM (Paris time). After the application deadline, all applications will first undergo an eligibility check. Eligible applications will then be reviewed during the pre-selection phase, scheduled for mid-October 2026. Shortlisted candidates will be invited to online interviews at the end of October 2026. Candidates selected following this first interview stage will then be invited to in-person interviews in Grenoble in early December 2026, with the final selection taking place after these interviews. All candidates will be informed of the outcome of the selection process following the final stage.
