-   Research talks from Infleqtion engineers and experts in the industry  
-   Primary internship location is Chicago, IL  

**Job Duties and Responsibilities** 

The duties and responsibilities outlined below include potential functions of the role. Depending on business needs, this role may perform a combination of some or all of the following duties. Duties, responsibilities, and activities may change, or new ones may be assigned. 

-   Conduct R&D toward cutting-edge advances in quantum technology with a focus on quantum compilation, similar to work described in [https://arxiv.org/abs/2309.05157](https://arxiv.org/abs/2309.05157) and [https://arxiv.org/abs/2509.13247](https://arxiv.org/abs/2509.13247)  
-   Deploy software optimizations to our cloud platform Superstaq using industry-grade software engineering procedures including documentation, linting, testing, and type-checking  
-   Interface with customers of Superstaq to understand their needs and support them in a timely fashion  
-   Contribute to development of government and commercial proposals and execution on global programs  
-   Collaborate with experimental physicists and software engineers to bridge the gap between theoretical concepts and practical implementation  
-   Engage with the broader scientific community by publishing research findings in scientific journals and presenting at conferences  
-   Stay up to date with the latest developments in quantum computer architecture, quantum compilation, quantum algorithms and applications, and related fields  
-   Provide guidance and support to other team members, fostering a collaborative research environment  
-   Tailor and apply quantum algorithms to real-world problems, analyzing their performance compared to classical methods  
-   Expand existing or develop new quantum algorithms for various types of real-world applications
