Nanofabrication Intern M/F

Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems.

The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit

🐈‍⬛

. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously!

We're a diverse team of 250+ brilliant minds from over 35 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together!

P urpose of the role

Superconducting qubits have come a long way in coherence time, but there is still room for progress. A major limit is microwave dielectric loss from two-level systems (TLS), which depends heavily on how circuits are fabricated.

Starting in March 2027,

you will join the Process Development Engineering Team for

• six months and work to extend the coherence time of our circuits by cutting material-related losses, optimizing cleaning steps and introducing deoxidation steps in the fabrication flow. Along the way, you will master advanced fabrication and characterization techniques to reach state-of-the-art performance.
• Responsibilities:: Review the state of the art in superconducting circuit fabrication techniques
• Fabricate superconducting circuits in a cleanroom environment (cleaning, lithography, etching, etc.)
• Characterize fabricated devices (SEM, EDX, AFM, basic room-temperature measurements, etc.)
• Continuously improve fabrication and characterization techniques

Requirements:: Master degree in Nanotechnology , applied physics

• Some knowledge of nanofabrication
• Proficiency in English
• The curiosity and rigor to keep improving a process, one experiment at a time
• Availability for a 6-month internship starting in March 2027
