Quantum algorithm for differential equations via permutation matrix representation with application to the Burgers equation

Hriday Sabharwal, Amir Kalev, Itay Hen

We develop a quantum algorithm for solving the dynamics of the nonlinear viscous Burgers equation. We apply the Carleman linearization procedure on the spatially discretized equati…

Advanced measurement techniques in quantum Monte Carlo: The permutation matrix representation approach

Nic Ezzell, Itay Hen

In a typical finite temperature quantum Monte Carlo (QMC) simulation, estimators for simple static observables such as specific heat and magnetization are known. With a great deal…
