Theoretical Physicist - Quantum Gate Design & Validation

Introduction

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

We offer

• Full time
• Hamburg or Siegen
