The Role:
We are looking for a Senior Optical Engineer to join our Quantum Networking Group. As an Optical Engineer, you’ll be part of a cross-functional team whose mission is to lead IonQ on its journey to build the world’s best quantum computers to solve the world’s most complex problems. In this role, you will be responsible for designing, prototyping, and validating advanced optical systems for quantum networking, specifically focusing on the development of high-fidelity Bell State Analyzers and quantum state tomography modules. The ideal candidate is a creative problem solver who thrives in navigating the intersection of classical optical engineering and experimental quantum physics.
Responsibilities:
- Design and simulate complex free-space and fiber-optic assemblies for quantum interference and entanglement distribution.
- Develop and characterize Bell State Analyzers (BSA) utilizing high-efficiency single-photon detectors and precise temporal/spatial overlap control.
- Implement automated quantum tomography protocols to characterize the fidelity of networked quantum states.
- Collaborate with the systems engineering team to integrate optical networking hardware into the broader IonQ quantum computer architecture.
- Execute rigorous experimental validation of optical components, including polarization extinction ratios, insertion losses, and interferometric stability.
- Optimize optical alignment procedures to transition laboratory-grade setups into robust, field-deployable quantum networking equipment.
Requirements:
- 5+ years of professional experience in Optical Engineering, Photonics, or Applied Physics with a focus on precision optical systems.
- Master’s degree in Optical Sciences, Physics, Electrical Engineering, or equivalent practical experie
