The UK government has announced a £121m investment boost into quantum technology to help tackle fraud and money laundering, which cost the economy £2.6bn a year.

Today is World Quantum Day, an annual celebration promoting public awareness and understanding of quantum science and technology around the world.

If quantum physics is the study of matter and energy at the most fundamental level, then quantum technologies exploit the properties identified by quantum physics to provide new capabilities in computing, communications and sensing.

While the field of quantum computing technology is still in its infancy, scientists believe that with its ability to work out problems that are unsolvable on classic computers, the technology could help power innovation in a range of fields, from drug discovery and smarter encryption software to manufacturing and AI.

A particular focus of this government investment is on using the technology to fight crime, tackle fraud and halt money laundering.
