A number of countries are working hard and investing huge sums of money to develop these super-fast quantum computers with a view to gaining strategic advantage in the cyber-sphere. Every day vast quantities of encrypted data – including yours and mine – are being harvested without our permission and stored in data banks, ready for the day when the data thieves’ quantum computers are powerful enough to decrypt it. quantum computers work completely differently from the computers developed over the past century. In theory, they could eventually become many, many times faster than today’s machines. How do you imagine Quantum computers to be like ?
