New technique to study molecules and materials on quantum simulator

A ground-breaking new technique has been discovered by physicist Oleksandr Kyriienko from the University of Exeter to study the properties of molecules and materials on a quantum simulator.

Current quantum computing methods for studying the properties of molecules and materials rely upon an ideal fault-tolerant quantum computer or variational techniques.

The scientist has shown that it is possible to exploit sequential evolution of the system with wave-function overlap measurements, such that effective study of ground state properties becomes possible with analog quantum simulators.

Therefore, this new proposed approach instead relies on the implementation of quantum evolution that would be readily available in many systems. The approach is favorable for modern state-of-the-art quantum setups, notably including cold atom lattices.

The research is published in the Nature journal npj Quantum Information. (
