Information is physical. It’s encoded in physical systems, like in the electrons that flow through our digital devices. This means it follows the rules of physics, and when information is encoded at a quantum level, the rules are often bizarre.
In this BrisScience, UQ's Dr Jacqui Romero highlights the differences between classical and quantum information, looking closely at ignorance — the absence of information, entirely or partly — in the quantum realm. She reveals research that could lead to world-changing technology – potentially un-hackable communication with higher information-capacity. Find out how real-world experimental science may one day lead to other-worldly communication systems.
