Theoretical Physicist – Quantum Gate Design & Validation (f/m/d)

eleQtron develops and operates full-stack quantum computers based on trapped-ion technology. Quantum computing is a new computing paradigm rapidly approaching commercial viability. Our unique approach combines laser-cooled trapped ions with microwave control and tailored magnetic fields. Our next-generation computing machines under development will be able to find solutions to problems that are out of reach today, thus enabling new innovative products and services for a brighter future.

To strengthen our theory team, we are looking for a Theoretical Physicist – Quantum Gate Design & Validation (f/m/d).

Responsibilities:

In this role, you will develop and analyze high-fidelity quantum gate mechanisms for trapped-ion processors. You will contribute to the theoretical modeling of physical interactions, translate them into optimized hardware-aware schemes, and collaborate with the experimental team for their implementation and validation. A key component of the position is contributing to performance benchmarking, ensuring consistency between theoretical predictions, numerical simulations, and experimental results.

• Develop theoretical models for single- and multi-qubit gate operations

• Analyze and optimize gate performance under realistic noise conditions

• Design and refine pulse schemes for robust quantum control

• Develop effective noise models connecting microscopic physical processes circuit simulators towards QEC and quantum applications

• Contribute to performance benchmarking and model validation

• Work at the interface between hardware and theory to guide device development and requirements engineering

Required skills:

• PhD in Physics or a closely related field

• Strong background in quantum optics and quantum technologies

• Excellent analytical skills in theoretical modeling, with strong proficiency in numerical simulations

• Ability to work effectively in an international, interdisciplinary team at the interface of theory and hardware

• Background in quantum control, open quantum systems, and quantum-classical noise is highly desirable

• Experience with trapped-ion systems is highly valued

What you can expect from eleQtron:

• Competitive salary: We value our team members and therefore provide remunerations that reflect this, additionally rewarding achievements.

• Flexible working hours: We offer personal freedom through a variety of flexible work schedules.

• Team spirit: In our international and diverse team, and with our regular team events, having fun at work is simply part of the game.

• Further development: We want to grow together and so we offer our team members’ needs-based, individualized further training as well as plenty of room for personal development.

• Wellness Package: We offer health-promoting benefits such as fitness programs like UrbanSportsClub to support your well-being.

• Moving Benefits: A warm welcome! We are happy to support employees who move for us with a bonus.

• At the forefront: Work at the forefront of technology, where academic research meets commercial applications.

• Modern workplace: We have a high-quality infrastructure with laboratory space, offices, and meeting rooms.
