Computers were once considered high-end technology, only accessible to scientists and trained professionals. But there was a seismic shift in the history of computing during the second half of the 1970s. It wasn’t just that machines became much smaller and more powerful — though, of course, they did. It was the shift in who would use computers and where: They became available to everyone to use in their own home.
The science and tech world has been abuzz about quantum computers for years, but the devices are not yet affecting our daily lives. Quantum systems could seamlessly encrypt data, help us make sense of the huge amount of data we’ve already collected, and solve complex problems that even the most powerful supercomputers cannot – such as medical diagnostics and weather prediction.
Quantum computers, which are based on the strange rules of quantum mechanics, will revolutionise society in a similar way to how mechanical computers have. Once built, they will help us answer many questions in science, create lifesaving medicines, provide transformative capabilities for the financial sector and in general solve certain problems that an ordinary computer would take billions of years to compute.
