Description

We illustrate the application of Quantum Computing techniques to the investigation
of the thermodynamical properties of a simple system, made up of three
quantum spins with frustrated pair interactions and affected by a hard sign problem
when treated within classical computational schemes.
We show how quantum algorithms completely solve the problem, and discuss how
this can apply to more complex system of physical interest.
