Global energy grids are under unprecedented stress as energy flows become more complex with the addition of intermittent energy sources and the artificial intelligence boom drives demand to new heights. Managing variable inflows and outflows of electricity while also keeping up with data center hyperscalers will require expanding and enhancing the grid at an unprecedented scale.

“Modernizing the grid to make it ‘smarter’ and more resilient through the use of cutting-edge technologies, equipment, and controls that communicate and work together to deliver electricity more reliably and efficiently can greatly reduce the frequency and duration of power outages, reduce storm impacts, and restore service faster when outages occur,” the United States Department of Energy writes. “Utilities also benefit from a modernized grid, including improved security, reduced peak loads, increased integration of renewables, and lower operational costs.”

The goal is to make the grid work smarter, not harder – and China thinks that the solution might be found in quantum mechanics. A team of researchers is working to apply quantum technologies in an exploratory project at a substation in Hefei, Anhui province in order to test how the approach could bolster grid resilience and reliability. The researchers are “using quantum sensors, secure communications and computing to detect faults, improve measurements and model grid operations,” according to a recent report from Interesting Engineering.

The substation has been the testing site for a series of quantum technologies since its construction in 2024, including an 18-month trial of quantum sensors used to detect defects and issues within the power grid. By using quantum technologies, these sensors are capable of detecting weak electrical signals and minute shifts in temperature and humidity within the station’s switchgear room, thereby protecting the station’s equipment and potentially detecting and stopping power outages before they start.

By researching and developing these cutting-edge technologies, China hopes to solve weak points in its conventional electrical grid, such as “delayed equipment monitoring, measurement errors, data-security risks and the computational load involved in analyzing complex power systems.” The researchers allege that this technology could ultimately “reduce electricity measurement errors at the substation by more than 500,000 kilowatt-hours per year.”

“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 Interesting Engineering.

Many scientists around the world are looking into how quantum technologies could solve some of the major challenges plaguing our energy sector today. Last year, the Nobel Prize in Physics was awarded for breakthrough work on quantum mechanics, emphasizing the growing importance and promise of the technology.

“A race is on across industry and academia to fulfill the promise of quantum computing, a strange and powerful technology,” the New York Times wrote this week as part of its report on the 2025 Nobel Prize in Physics. The enormous power of the field can be as frightening as it is exciting. “A true quantum computer could accelerate the progress of drug discovery or other scientific research. It could also break the encryption that protects computers vital to national security.”

Indeed, quantum technologies are already transforming clean energy research in diverse contexts around the globe. At the Institute of Science Tokyo, a team of scientists used quantum states to design a novel form of energy harvester dreamt up by a research team at the Institute of Science Tokyo, capable of reclaiming energy lost to the heat that emanates from electronics and industrial machinery. Over in the United States, at MIT, researchers recently announced that they have discovered a method to observe a so-called “edge state” of electrons that results in a lack of energy loss, with enormous disruptive potential for the tech sector. And breakthroughs in quantum batteries also hold promise for harvesting energy directly from light sources and recharging many times faster than lithium-ion batteries.

While all of these applications show enormous promise for transforming the global energy sector for the better, few uses are as urgently needed as grid modernization. In an era characterized by complex energy insecurities at a global scale, creating smarter and more reliable energy grids is a matter of international priority.
