• 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
