China Plans to Expand Quantum Technology Use Across Power Grid

China plans to expand the application of quantum technologies – including precision sensors and computer simulations – across its power grid to help prevent blackouts.

The push follows a successful trial at a substation in Hefei, Anhui province.

During the 18-month trial, quantum technology was used to rapidly detect and diagnose equipment defects and faults in the power system, according to a report published on Wednesday by the state-run People’s Daily.

Quantum technology harnesses the physics governing individual atoms, in which they exist in multiple states simultaneously until they are measured, a phenomenon known as “superposition”.

This can be used to measure, compute and communicate data in a variety of ways. While its applications are only beginning to transition from research labs to the real world, it can offer major advantages, especially in precision, speed and security.

“The operation has proved that quantum technology is not a ‘showpiece’, but a ‘hard support’ for guaranteeing the power supply and promoting development,” Tian Teng, a researcher with Anhui Electric Power Company, was quoted by the report as saying.
