The Feld Group works on full-stack quantum computing, from architecture to applications. We investigate how quantum computers should be designed, programmed, and operated so that promising quantum algorithms can become reliable computations on real hardware.

Rather than considering the different layers of a quantum computer independently, we study how they interact. Our work connects quantum computer architecture with compilation and system software, reliable quantum computation, and quantum algorithms for realistic applications. A central theme is hardware-software co-design: using insights across the quantum computing stack to jointly improve hardware architectures, software methods, and applications.

Our main research directions include:

• Quantum computer architecture: developing scalable and modular architectures and exploring how architectural choices affect the execution of quantum algorithms.
• Quantum compilation and systems: developing hardware-aware compilation, mapping, and resource-efficient methods for executing quantum programs on real devices.
• Reliable quantum computing: developing methods that make quantum computation more robust and reliable in the presence of imperfect hardware.
• Quantum algorithms and applications: developing and studying quantum algorithms for realistic optimization, planning, engineering, and other computational problems.
