Join Us at the Forefront of Quantum Computing Innovation 🚀

### **About the FTQC Team**

We are the company’s forward-guard, working to identify the best paths forward for our technology, its architecture, and its applications in quantum computing. We study hybrid spin-optical architecture, fault-tolerance, logical gates, magic states and we push the limits of Quandela's technology.

### **Description of the Project**

This internship aims at developing novel fault-tolerance strategies for Quandela's SPQOC architecture.

The project explores how this architecture could be extended with high-rate quantum codes to improve encoding density without sacrificing reliability or computational flexibility.

Develop practical experience with simulation of fault-tolerant circuit, quantum LDPC codes, and architecture design.

### **Your Key Responsibilities**

-   Participate in the FTQC group meetings and meet regularly with supervisors;
-   Develop an understanding of existing methods for simulating and evaluating fault-tolerant circuits;
-   Develop knowledge on high-rate qLDPC codes and on the SPOQC architecture;
-   Contribute to the implementation of concatenated high-rate codes on SPOQC's bi-planar architecture;
-   Present your work internally.
