Senior Quantum Photonics Engineer - Optical Interconnects

IQM Quantum Computers; Espoo; On-site; EUR 70,000 - 110,000; Full time

Job summary

IQM Quantum Computers in Espoo, Finland, seeks a highly skilled researcher to advance superconducting quantum computing with optical links. You will build and run experiments in a dilution refrigerator, characterizing cryogenic components and implementing control pathways to push qubit fidelity.

You will design tests for single and two-qubit gates, analyze noise, and document results while collaborating with partners and researchers on grant projects.

Qualifications

• PhD in applied physics, electrical engineering or a related field.
• At least five years of relevant academic or industrial experience in electronics, photonics or quantum computing.
• Practical experience running quantum related or active electronics experiments in a dilution refrigerator.
• The ability to independently set up, troubleshoot, run and document experiments, including operating a dilution refrigerator and installing samples.
• Experience with RF and microwave measurement equipment, such as network analyzers and pulse generators.
• Python skills for scientific programming, measurement automation and data analysis.
• Understanding of analogue and digital electronics, including noise, drift, signal to noise ratio and bandwidth.
• Clear written and spoken English, with the ability to explain technical findings and coordinate work across internal and external stakeholders

Responsibilities

• Build and develop an experimental platform for superconducting quantum computing with optical communication links.
• Design and run experiments in a dilution refrigerator, including optical signal paths, swapping and mounting samples, optimizing RF and microwave environment with heat conductivity and dissipation budget in mind, and automate measurements.
• Characterize optical and cryogenic electronic components, including cryogenic photodiodes, lasers and modulators.
• Develop experiments to demonstrate and characterize single and two qubit gates and qubit readout using optical interconnects.
• Simulate and analyze gate fidelities, noise, drift, and dissipation to identify limitations and explore ways to improve performance.
• Evaluate technology options and scalability requirements for the quantum computer control stack and signal path.
• Document results and communicate findings to colleagues, technical decision makers, and external research partners.
• Own technical contributions to grant projects, including reporting, proposals and coordination with partner companies and institutes.
