TITLE:    Programmable Simulations of Molecules and Materials with 
Reconfigurable Quantum Processors

ABSTRACT:

Simulations of quantum chemistry and quantum materials are believed to 
be among the most important potential applications of quantum 
information processors, but realizing practical quantum advantage for 
such problems is challenging. Here, we introduce a simulation framework 
for strongly correlated quantum systems that can be represented by model 
spin Hamiltonians. Our approach leverages reconfigurable qubit 
architectures to programmably simulate real-time dynamics and introduces 
an algorithm for extracting chemically relevant spectral properties via 
classical co-processing of quantum measurement results. We develop a 
digital-analog simulation toolbox for efficient Hamiltonian time 
evolution utilizing digital Floquet engineering and hardware-optimized 
multi-qubit operations to accurately realize complex spin-spin 
interactions, and as an example present an implementation proposal based 
on Rydberg atom arrays. Then, we show how detailed spectral information 
can be extracted from these dynamics through snapshot measurements and 
single-ancilla control, enabling the evaluation of excitation energies 
and finite-temperature susceptibilities from a single-dataset. To 
illustrate the approach, we show how this method can be used to compute 
key properties of a polynuclear transition-metal catalyst and 2D 
magnetic materials.
