Job summary

Xanadu is seeking a Senior Scientist - Quantum Sources to advance photonic modules for large-scale quantum systems. You will transform bare photonic chips into deployable hardware, leading integration and validation of quantum source modules with active interferometers and high extinction ratio filters.

You will collaborate with PIC designers and engineering teams to define interfaces, optimize control strategies, and document module specifications for system-level handoffs.

Qualifications

• PhD in Quantum Optics, Photonics, AMO, Applied Physics, or related field.
• Hands-on experience in experimental optics labs with integrated optics and fiber optics.
• Experience generating and characterizing non-classical light (squeezed states, multi-photon) and homodyne detection.
• Experience with active stabilization of optical phases and PID controllers.
• Experience writing Python scripts for instrument control and data acquisition.

Responsibilities

• Lead assembly, integration, and validation of quantum source modules.
• Characterize generation of advanced quantum states with integrated squeezers and active routing.
• Collaborate with PIC designers, electrical, mechanical, and systems engineers to define module interfaces.
• Develop and optimize control strategies for optical components and stabilize interferometric networks.
• Provide measurement-driven feedback to PIC design and component testing teams.
• Create detailed technical documentation and handoffs for system-level deployment.
