Block-encoding structured matrices for data input in quantum computing

Christoph Sunderhauf
Riverlane

This talk will argue that data loading can be an important bottleneck for quantum algorithms. The concept of block encodings, a popular data input model, is introduced, along with its use-cases like the quantum singular value transformation. I will show how our work can leverage structure present in the input matrices to construct low-cost block encoding circuits. I'll also explain how the circuits work and try to convey how I think about them.

Bio: Christoph discovered his passion for quantum theory in the second year of his university studies in Heidelberg, London, and St. Louis, MO. His PhD at the Max-Planck-Institute of Quantum Optics, Munich, focused on chaos in many-body quantum systems. Since 2021, he has been a researcher at Cambridge, UK based quantum computing startup Riverlane, where he thinks about quantum algorithms and applications for tomorrow’s fault-tolerant quantum computers. Among his hobbies is hiking, and he looks forward to exploring some of the trails in Los Alamos.
