Scaling Quantum Computers with Photonics: A System-Level Perspective on Opportunities and Hurdles

Quantum computers promise transformative impact across industries, from pharmaceuticals to logistics. A critical challenge on the path to fault-tolerant systems is not only scaling the number of qubits but also preserving precision at scale. Photonics plays a central role in meeting this challenge. In platforms such as trapped ions and neutral atoms, photonic technologies enable qubit initialization, gate operations, state detection, and system interconnects.

This talk will explore why scaling demands a system-level approach moving beyond individual lasers, modulators, and detectors. Dhimitri highlights how photonics can serve as the backbone for scalable quantum platforms, bridging the gap between component performance and system-level architecture.
