Post-doctoral Reseracher on SiGe-based cryogenic amplifiers for quantum computing

The Nanoscience Cooperative Research Center nanoGUNE, located in Donostia / San Sebastian, Basque

Country (Spain), is currently looking for a

Post-doctoral Researcher

to work on

SiGe-based cryogenic amplifiers for quantum computing

NanoGUNE is a research center devoted to conducting world-class nanoscience research for a competitive growth of the Basque Country. NanoGUNE is a member of the Basque Research and Technology Alliance (BRTA) and is recognized by the Spanish Research Agency as a María de Maeztu Unit of Excellence.

We are please to offer a Postdoctoral position in the field of Cryogenic electronics for Quantum Computing at nanoGUNE. The project is part of a collaborative effort between academic and industrial partners to develop low-noise, low-power cryogenic amplifiers for solid-state qubits. The selected candidate will join a multidisciplinary collaboration between IC designers and Quantum Scientist and Engineers. The candidate will be responsible for agreeing the specifications of the low-noise amplifier (LNA), contributing to the design, test it in isolation at room and deep cryogenic temperatures and demonstrate it operation alongside qubit devices.  

Key responsibilities:

• Establish the LNA specifications for best performance with semiconductor spin qubits.
• Build cryogenic test set ups to test the LNAs in isolation and alongside qubit devices.
• Perform S-parameter and noise characterisation of the LNAs (0.1-2 GHz)
• Perform electrical characterization of silicon devices at millikelvin temperatures and high magnetic fields.
• Perform dynamical operations on spin qubits using high frequency electronic equipment.
• Collaborate with interdisciplinary teams, quantum scientist and engineers and IC designers.
• Analyse and interpret experimental data, contributing to scientific publications, patents, and presentations.
• Engage with the wider international research community by participating in conferences, workshops, and collaborative projects.

Qualifications:

• PhD in Physics, Electrical Engineering, or a related field from a top tier university/research centre.
• Background in solid-sate physics, semiconductor devices, quantum information, and/or analogue circuits is desirable.
• Experience in data analysis and programming, particularly in the use of Python, Git, and Gitlab.
• Excellent communication skills in English, both written and verbal.
• Ability to work independently and as part of a collaborative research team.

Conditions:

• A postdoctoral salary for (1.5 years) with possibility to extend the contract.
• Access to state-of-the-art cryogenic laboratory facilities including Bluefors Gen2 dilution refrigerators, high end electronics and computational resources.
• Opportunities for research stays at partner academic and industrial institutions, participation in conferences, and involvement at international collaborations.
• Comprehensive health insurance (as per nanoGUNE and EU regulations).

The position is available as early as 01/06/2025.

Interested candidates should apply by filling in the form below and by submitting the following documents in a single PDF file:

• A detailed CV, including academic background and relevant experience. We particularly welcome experimental experience in a laboratory setting.
• Contact information for two references.

Deadline to apply: 31/05/2025

For informal enquiries, interested candidates are welcome to contact Prof. M. Fernando Gonzalez Zalba (f.gonzalez@nanogune.eu).

Candidates will be assessed as they apply and the call will remain open until the suitable candidate is identified.
