Useful imperfections: Nanodiamonds for quantum sensors in living cells

By Shane Huntington

Physicist Prof Lloyd Hollenberg explains how quantum technologies are leading to the development of sensors of only a few atoms’ size – small enough to be placed inside living cells to enable monitoring of biological processes.

I’m Dr Shane Huntington. Thanks for joining us. Sensors are all around us. We find them in our cars, on the front of our television screens and even in the humble household kettle. Each sensor is designed to determine a particular state of its external environment. Sensors detect engine temperature in our cars, infrared signals from our television remote controls and when the water is boiled so that our kettles shut off safely. All these common sensors are physically quite large, certainly large enough to be seen and touched. But the promise of quantum technologies suggest we'll soon be able to design and build sensors to the size of only a few atoms, small enough to fit inside one of our cells. Will these tiny sensors work in the same way as their larger cousins? What new insights can they give us about the inner workings of our bodies, and what influence would the strange effects of quantum mechanics have on the way these sensors do their job? To answer these questions and help us explore the world of quantum sensors we are joined by physicist Professor Lloyd Hollenberg, Deputy Director of the Australian Research Council Centre of Excellence for Quantum Computation and...
