Australia could become home to the world's first commercially useful quantum computer, with the Federal and Queensland Governments investing nearly a billion dollars to build and house the technology in Brisbane. Quantum computers have long been touted for their potential to revolutionize a range of scientific fields.
He says it’s this phenomenon - of existing in multiple states at the same time – that is key to the technology. But what if, instead of this long process of trial and error, you could rule out all the incorrect paths in one go?"What a quantum computer does, is it finds the right path by having the wave functions of the computer interfere all the wrong paths away. So you just get the right answer at the end."
Scientists say quantum computing could be a game-changer in medical research, weather forecasting, climate change modelling, the development of batteries, cybersecurity, renewable energy and artificial intelligence.Heat, electrical and magnetic fields can all cause the system to crash, and so they need to be kept in very cool, controlled rooms.
