The elusive quantum computer. Theoretical next phase in computing and thus humanity. Old encrypted messages suddenly cracked in a flash. Complex scientific problems solved before lunch. Not just on/off anymore, these beasts can deal with uncertainty. Should we be paying more attention to these, are they imminent? "Quantum computing could change the world. It could transform medicine, break encryption and revolutionise communications and artificial intelligence. Companies like IBM, Microsoft and Google are racing to build reliable quantum computers. China has invested billions. Recently, Google claimed that it had achieved quantum supremacy – the first time a quantum computer has outperformed a traditional one. But what is quantum computing? And how does it work?"

Quantum compting

Right now, we don't know if quantum computers will be just a specialized tool, or a big revolution for humanity" Its quantum, it's gonna be both things at once.

IBM and Google are racing to create a truly useful quantum computer. Here's what makes quantum computers different from normal computers and how they could change the world

Quantum computing could change the world. It could transform medicine, break encryption and revolutionise communications and artificial intelligence. Companies like IBM, Microsoft and Google are racing to build reliable quantum computers. China has invested billions. Recently, Google claimed that it had achieved quantum supremacy – the first time a quantum computer has outperformed a traditional one. But what is quantum computing? And how does it work?

Right now, supercomputers can only analyse the most basic molecules. But quantum computers operate using the same quantum properties as the molecules they’re trying to simulate. They should have no problem handling even the most complicated reactions.

"If you ask a normal computer to figure its way out of a maze, it will try every single branch in turn, ruling them all out individually until it finds the right one. A quantum computer can go down every path of the maze at once. It can hold uncertainty in its head."
