Preparing thermal states on noiseless and noisy programmable quantum processors

Understand

Nature is governed by precise physical laws, which can inspire the discovery of new computer-run simulation algorithms.

• Thermal states are the most ubiquitous for they are the equilibrium states of matter.
• Simulating thermal states of quantum matter has applications ranging from quantum machine learning to better understanding of high-temperature superconductivity and quantum chemistry.
• The computational complexity of this task is hopelessly hard for classical computers.
