Practical Quantum Circuits for Block Encodings of Sparse Matrices

Explore practical quantum circuits for block encodings of sparse matrices in this 38-minute conference talk presented by Chao Yang from Lawrence Berkeley National Laboratory. Delve into the world of quantum numerical linear algebra as Yang discusses how standard linear algebra problems can be solved on quantum computers using block encoding and quantum singular value transformation techniques. Learn about the challenges and strategies for constructing efficient quantum circuits, particularly for well-structured sparse matrices and stochastic matrices corresponding to random walks on graphs. Discover how these techniques can potentially achieve exponential speedup in solving linear algebra problems compared to classical computers, and gain insights into the implementation of efficient quantum walks through block encoding.
