You’ll collaborate with leading scientists, engineers, and visionaries to push boundaries and turn ideas into reality. With a culture built on curiosity, creativity, and collaboration, IBM Research offers the opportunity to grow your career while contributing to breakthroughs that transform industries and change the world.

Your Role And Responsibilities

As a research intern with the IBM Theory of Quantum Algorithms team, you will work alongside our theorists to discover and develop new quantum algorithms for scientifically and practically meaningful problems, with a focus on algorithms designed for fault-tolerant quantum computers. Your project will be shaped in collaboration with your mentor and may draw on areas such as quantum algorithm design, computational complexity theory, quantum simulation, algorithms for differential equations, and quantum approaches to learning and testing. Over the course of the internship, you will:

• Investigate a well-defined research question in quantum algorithms, working toward original theoretical contributions suited to fault-tolerant quantum computation.
• Characterize potential quantum speed-ups by comparing candidate algorithms against state-of-the-art classical methods, using tools from computational complexity theory.
• Consider how your algorithmic ideas connect to implementations suited to fault-tolerant quantum architectures, in discussion with colleagues across compilation and error correction.
• Document and present your findings, with the goal of producing results suitable for a peer-reviewed publication or conference submission.
