The UK’s security and prosperity strongly depends on the sea. This includes the stability of the global supply chain, freedom of navigation, protecting offshore and undersea infrastructures, naval power and forces projection, sea-based deterrence and addressing maritime crimes, such as illegal fishing. Yet sea blindness, i.e., a lack of understanding of the importance of the sea, characterises many decision-making processes.

While quantum physics can sound overwhelming at first, it’s just a set of rules for how everything behaves at very small scales. Conventional electronics tells us how circuits operate and quantum physics, for example, describes the behaviour of single electrons in these circuits. As the rules that quantum physics imposes are different from those of the classical world, we can make real devices that harness them, which are capable of doing things that would otherwise be impossible.
