Over the last century, quantum physics has transformed the human world. All of today’s digital and communications kit—and much of current energy production—has been made possible by the application of quantum effects to produce transistors, computers, lasers and imaging.

Today new quantum technologies (QT) are again poised to transform human activity. The second wave of QT harnesses aspects of subatomic particle behaviour called ‘superposition’ and ‘entanglement’. Superposition describes the property of a particle being in two or more states at once. Entanglement is when two particles are so connected that they are one whole system—not two separate components—even when the two particles are separated by thousands of kilometres. 

Harnessing these characteristics allows quantum computers, for example, to increase computational capacity and speed beyond anything available today. Quantum sensors provide information from around corners and deep underground, and quantum communication devices will enable highly secure, protected communication. All of these technologies have military applications. The full set is currently beyond imagination, but it is possible to start suggesting what some of these applications will be.

This session will look at these new technologies, their state of development and deployment and what can be expected from them, how they will be applied to the military battle space, and ways of envisaging their use and control.
