Quantum computing holds the potential to have real-world applications that transform lives. In comparison with traditional computing, quantum computing systems can evaluate many possibilities at once, making it faster and easier to solve complex problems.

Stavros Christopoulos, associate professor of physics at Sorbonne University Abu Dhabi, is a researcher in the field of quantum sensing. An emerging field of sensor technology, quantum sensing uses properties of quantum mechanics to make precise measurements of physical quantities such as acceleration, temperature or gravity. “This is more energy-efficient and robust,” says Christopoulos. 

Quantum computing could have applications in areas such as drug discovery and development, material science and climate issues. It can enable researchers to simulate complex systems, such as weather predictions or forecasting models for financial stocks. “It could solve one problem and alleviate another at the same time. For example, drawing carbon dioxide from the atmosphere and channelling it to where it is needed,” Christopoulos says. 

Because the infrastructure for quantum computing requires specific ambient conditions, these systems tend to be hosted by companies such as IBM or Google or at national computing laboratories and research institutions. Some of them can be accessed by researchers or other companies publicly in the same way they might access a cloud-based system. 

“But even when the systems work properly, there are technical challenges,” says Christopoulos. “In the future, the processes and software we now have will need to be based on this new, quantum-based hardware. It cannot work on the same coding approach as before.” The building blocks of quantum computing, known as qubits, are linked and affect each other. A broken connection can cause the system to produce errors, so testing and oversight are important.  

Building and monitoring new tools requires a sustainable stream of talent who are experts in quantum computing. “This starts with discussing the basic principles of quantum mechanics with students early, so they’re not encountering it for the first time when they do a master’s degree or PhD,” Christopoulos says. “We have to be more ambitious about creating a new generation of quantum-literate people who can produce results for all sectors.”

Sorbonne University recently invited five quantum computing start-ups to join the new incubator at its Paris campus to further expand its quantum ecosystem, with the academics in the sciences and engineering department at Sorbonne University Abu Dhabi working closely with them.  

Christopoulos explains that while quantum computing may be complex and require robust testing, it will ultimately create positive outcomes for populations, including better public health and a reduction in environmental harm. “We will be able to decode many things from a scientific perspective, creating better solutions for health and the environment that affect our everyday lives,” he says.
