About Xanadu : Xanadu ’s mission is to build quantum computers that are useful and available to people everywhere.
At Xanadu , we are learners, innovators, researchers, collaborators, and problem solvers. We are creating something that has never been built before. What we are doing is extremely hard, the classic moon shot. Few people in their life will be able to be a part of something like this, where if we are successful, the technologies we develop will solve some of the world’s most challenging problems, and literally change the world. That is something to be excited about!
Your role and responsibilities:As a quantum scientist, you will join a technical team of scientists dedicated to unlocking the real-world impact of fault-tolerant quantum computers. You will contribute to discovering cutting-edge quantum algorithms, rigorously optimizing their performance, and identifying valuable applications across a variety of industries. Whether your primary strength is pioneering algorithms or uncovering novel applications, this role thrives at the intersection of both. At Xanadu , this research is conducted alongside industry, government, and academic partners, requiring close collaboration with software, hardware, and business development teams across the company.
In more detail, you will focus deeply on:
Designing and pioneering innovative quantum algorithms tailored for fault-tolerant quantum computers for applications related to computational chemistry.
Radically improving algorithm efficiency by reducing qubit counts, gate complexity, and overall resource requirements Identifying high-value applications targeted at our chemistry-related focus industries.
Demonstrating the feasibility and scalability of new algorithms and applications through rigorous resource estimation and comparison to state-of-the-art classical methods.
Collaborating with PennyLane software developers to create state-of-the-art tools for quantum algorithms research.
Regardless of your specific focus areas, you will consistently:
Author high-quality scientific papers, technical reports, and comprehensive documentation.
Generate valuable intellectual property and actively support the filing of related patents.
Present your research findings to strategic partners and at premier conferences and events.
Basic qualifications and experience:
