Linear Combination of Hamiltonian Simulation for Non-Unitary Dynamics - IPAM at UCLA

Explore a cutting-edge method for simulating non-unitary dynamics in quantum systems through a 51-minute lecture presented by Dong An from the University of Maryland Joint Center for Quantum Information and Computer Science. Delve into the innovative Linear Combination of Hamiltonian Simulation (LCHS) approach, which offers advantages over traditional techniques by avoiding the need for dilated linear system problems or reliance on the spectral mapping theorem. Discover how LCHS achieves optimal cost in state preparation and its potential applications in open quantum dynamics simulation using the complex absorbing potential method. Gain insights into the method's near-optimal performance across various parameters and its implications for advancing quantum algorithms in scientific computation.
