The original motivation to build a quantum computer came from Feynman, who imagined a machine capable of simulating generic quantum mechanical systems—a task that is believed to be intractable for classical computers. Such a machine could have far-reaching applications in the simulation of many-body quantum physics in condensed-matter, chemical and high-energy systems. Part of Feynman’s challenge was met by Lloyd, who showed how to approximately decompose the time evolution operator of… 
A quantum–quantum Metropolis algorithm
TLDR
This work presents a quantum algorithm which fully generalizes the classical Metropolis algorithm to the quantum domain, and offers a quantum speedup relative to the classical counterpart.
Metropolis-style random sampling of quantum gates to estimate low-energy observables
In many areas of physics, we are often interested in calculating observables when the physical system is in, or is around, its lowest energy state. One particularly difficult problem of this nature

TLDR
A quantum algorithm to compute expectation values of observables in a finite energy interval for many-body problems based on a filtering operator, similar to quantum phase estimation, which recovers the physical values by performing interferometric measurements without the need to prepare the filtered state.

Quantum algorithm for preparing thermal Gibbs states - detailed analysis
TLDR
A modified algorithm and a more detailed analysis of the errors that arise due to imperfect simulation of Hamiltonian time evolutions and limited performance of phase estimation are presented to prove a better running time by the effect of these sources of error on the overall complexity.

The Power of Quantum Systems on a Line
TLDR
The proof of the QMA-completeness result requires an additional idea beyond the usual techniques in the area: Some illegal configurations cannot be ruled out by local checks, and are instead ruled out because they would, in the future, evolve into a state which can be seen locally to be illegal.
