Join Us at the Forefront of Quantum Computing Innovation

Description of the Team/Project

The Device Physics team works on the development and optimisation of quantum dot (QD)-based spin qubits, focusing on the physical implementation of quantum operations and their impact on fault-tolerant quantum computing.

We are looking for a motivated intern to investigate the noise and error mechanisms associated with Optical Spin Rotation Pulses (OSRPs). The internship will involve developing physical models and numerical simulations to translate device-level errors into effective error channels that can be used in quantum error-correction (QEC) simulations.

Your Key Responsibilities

• Participate in Device Physics group meetings and meet regularly with supervisors.

• Develop an understanding of existing methods for simulating Optical Spin Rotation Pulses (OSRPs) and analytical error analysis techniques.

• Contribute to the development of physical models describing OSRP implementation and assess the physical implications of simplifying assumptions.

• Develop numerical simulations and analytical descriptions of error channels generated by the selected physical models.

• Combine derived errors with existing perturbative descriptions of single-qubit gates to analyse their impact on resulting error channels.

• Investigate the impact of modelled OSRPs on the optical properties of quantum dots and explore their potential use in pulse optimisation.

• Study temporal correlations and non-Markovian effects arising from repeated OSRPs.

• Incorporate derived OSRP error channels into quantum error-correction simulations and evaluate their impact on logical error rates.

Education & Background

• MSc student in Quantum Information Science, Quantum Engineering, Quantum Computing, Physics or a closely related field.

Technical Skills

• Knowledge of quantum optics and open quantum systems and quantum information theory.
• Understanding of quantum error correction and awareness of the role errors in fault tolerant quantum computing.
• Experience with numerical modeling of quantum systems in Python or C++ ideally with tools like QuTiP and Qiskit.
• Understanding of analytic techniques such as perturbation theory.

Soft Skills

• Strong analytic and problem solving skills
• Clear written and verbal communication
• Ability to work in a team and independently

Languages

• Fluent English, written and spoken, is required

• Swile Card (meal vouchers)

• 50% participation in transportation costs

• Possibility of remote work
• Internship Allowance between €1,200 and €1,400 per month

• 1,5 days off per month, cumulative
