Summer 2027 Internship - Quantum Software (QSW)

This internship program is within our Quantum Software (QSW) division. Interns work closely with Infleqtion’s Quantum Software Engineers and are paired with a mentor on the team. This program is intended to run for 10 to 12 weeks. Features of the program include: 

• Contribution to cutting-edge quantum software solutions from application to middleware layers  
• Weekly 1:1 meetings with your mentor to discuss summer projects and professional development  
• 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 and 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
