Description

**Title**: Quantum algorithms for linear differential equations

**Speaker**: Dong An (https://dong-an.github.io/)

**Abstract**: Quantum computers are expected to simulate unitary dynamics (i.e., Hamiltonian simulation) much faster than classical computers. However, most applications in scientific computing involve non-unitary dynamics and processes. In this talk, we will discuss a recently proposed quantum algorithm for solving general linear differential equations. The idea of the algorithm is to reduce general differential equations to a linear combination of Hamiltonian simulation (LCHS) problems. For the first time, this approach allows quantum algorithms to solve linear differential equations with near-optimal dependence on all parameters. Additionally, we will discuss a hybrid quantum-classical differential equation algorithm based on LCHS, which may be more feasible on near-term quantum devices.

We will have the Departmental Coffee and Tea from 10 to 10:45 in M&P 422.
