    The fundamental building blocks of iterative linear algebra algorithms in ordinary digital computation are matrix–vector multiplications and inner products. In quantum computing, we lose easy access to both primitives. But we also gain replacements. Instead of matrix–vector products, we can apply the unitary time evolution operator $e^{-itA}$, and we have access to noisy—but statistically...

    Quantum computing relies heavily on the efficient manipulation of linear algebraic structures. This talk discusses the application of quantum linear algebra across two major domains: continuous optimization and differential equations. We demonstrate how quantum linear algebra can be utilized to solve these problems efficiently, discussing both the algorithmic construction and the theoretical...

    Quantum linear algebra has emerged as a promising framework for accelerating the solution of fundamental computational problems, including systems of linear equations—a core subroutine in many scientific and engineering tasks. These problems arise prominently in optimization algorithms. In this talk, we discuss the opportunities and challenges associated with integrating quantum linear algebra...

    Quantum Krylov methods are strong candidates for computing ground states on NISQ and MegaQuop computers. While typically implemented with powers of the time evolution unitary $e^{-iH t}$ for a given Hamiltonian $H$, convergence can be markedly faster with powers of the Hamiltonian $H$ itself as in classical methods. We discuss these convergence rates and present several ways to implement...

    The emergence of Quantum Numerical Linear Algebra (qNLA) offers a paradigm shift in solving large-scale linear systems and matrix functions. However, the practical utility of these algorithms, such as the seminal HHL, is fundamentally bottlenecked by the "input problem", namely the efficient representation of classical matrices as quantum circuits.

    In this talk, we explore two distinct...

    Quantum block encoding (QBE) is a crucial step in the development of most quantum algorithms, providing an embedding of a given matrix into a suitable larger unitary matrix. Efficient techniques for QBE have primarily focused on sparse matrices, and less effort has been devoted to data-sparse matrices, such as rank-structured matrices.

    In this talk, we examine a specific case of rank...

    With the Quantum Singular Value Transformation (QSVT) emerging as a unifying framework for diverse quantum speedups, the efficient construction of block encodings—their fundamental input model—has become increasingly crucial. However, devising explicit block encoding circuits remains a significant challenge. A widely adopted strategy is the Linear Combination of Unitaries (LCU) method. While...

    Quantum circuits naturally implement unitary operations on input quantum states. However, non-unitary operations can also be implemented through “block encodings”, where additional ancilla qubits are introduced and later measured. While block encoding has a number of well-established theoretical applications, its practical implementation has been prohibitively expensive for current quantum...
