报告题目: Quantum Computation of partial differential equations
时 间:3月26日(星期日)8:30-9:30.
地 点:理工楼 631
报告摘要:Quantum computers have the potential to gain algebraic and even up to exponential speed up compared with its classical counterparts, and can lead to technology revolution in the 21st century. Since quantum computers are designed based on quantum mechanics principle, they are most suitable to solve the Schrödinger equation, and linear PDEs (and ODEs) evolved by unitary operators. The most efficient quantum PDE solver is quantum simulation based on solving the Schrödinger equation. It became challenging for general PDEs, more so for nonlinear ones. Our talk will cover three topics:
1)We introduce the “warped phase transform” to map general linear PDEs and ODEs to Schrödinger equation or with unitary evolution operators in higher dimension so they are suitable for quantum simulation;
2)For (nonlinear) Hamilton-Jacobi equation and scalar nonlinear hyperbolic equations we use the level set method to map them exactly to phase space linear PDEs so they can be implemented with quantum algorithms and we gain quantum advantages for various physical and numerical parameters.
3)For PDEs with uncertain coefficients, we introduce a transformation so the uncertainty only appears in the initial data, allowing us to compute ensemble averages with multiple initial data with just one run, instead of multiple runs as in Monte-Carlo or stochastic collocation type sampling algorithms.
欢迎广大师生光临!
