Femtosecond laser writing for photonic quantum processors

Introduction

Ephos is a photonic quantum computing company. Our objective is to build the key element of the infrastructure to power quantum computing: photonic chips. Ephos has a unique asset to reach this goal: it is the only photonic quantum start-up in the world with in-house chip manufacturing capabilities.

Technology and Process

We build our glass-based photonic quantum processors using a femtosecond laser writing (FLW) process developed by our founding team. Our fabrication process, with respect to those of our competitors, is:

• Faster
• Lower-cost
• Higher flexibility
• Capable of working with 3D structures

The resulting chips have low interface losses, which makes them the ideal building blocks of the modular architectures that are the leading contender to deliver scalable quantum computation.

Project Aim

The aim of the current project is to support Ephos in establishing the world's most advanced FLW facility for the production of quantum photonic chips.

Expected Outcomes

Over the course of this project, we will build the largest programmable quantum photonic processor in the market. This project will enable the development of more powerful and efficient quantum computing technologies that have the potential to revolutionize various industries.

Additionally, the lower-cost and higher flexibility of Ephos' fabrication process could potentially make quantum computing more accessible for a wider range of organizations and researchers.
