Cavilinq welcomes Sophie Ding to the team

We’re excited to welcome Sophie (Weiyi) Ding to CavilinQ as our Founding Engineer, leading the photonics effort.

Sophie joined the team earlier this year and brings deep expertise in photonics and quantum hardware. She completed her undergraduate studies at Caltech and earned her PhD from Harvard University under Prof. Marko Lončar, where she developed some of the highest quality-factor cavities demonstrated in diamond, along with novel photonic architectures. Her work also includes the development of buckled mirror technology that forms part of CavilinQ’s licensed IP from Harvard. Following her PhD, she worked at Amazon Quantum, contributing to the development of superconducting quantum systems.

At CavilinQ, Sophie leads our photonics efforts, driving the design and development of cavity-based architectures that form the backbone of our interconnect technology. Her work is central to building and demonstrating early prototypes, and to establishing the foundation for scalable, modular quantum systems. Scaling quantum systems will require advances in light–matter interfaces, and Sophie’s work directly enables this transition.

“Light–matter interfaces sit at the heart of scalable quantum networking. At CavilinQ, we have the opportunity to push those boundaries in a meaningful way, and I'm glad to be a part of the effort.”

We’re thrilled to have Sophie on the team and are excited to build the next generation of scalable quantum systems together.
