"But for at least some types of problems, quantum computers will be able to check all potential solutions at once.In addition, with traditional digital computers, to double the speed at which it operates, you need to double its number of bits.But with quantum computers, the speed they can operate at doubles every time you add a new qubit.Those two properties combined means the moment quantum computers outpace traditional computers, they are on an exponential path to unimagined computing power.Take internet cryptography as an example. The fact that traditional computers work in series rather than parallel is relied on for a huge amount of cryptography.That sort of cryptography keeps all your banking and sensitive communication safe.Breaking cryptography with current computers is technically possible — it would just take thousands of years.It involves a problem for which there are many solutions that traditional computers must examine one after another.But quantum computers will be able to break cryptography almost instantly by examining all the possible solutions at once.Even though proper quantum computers don't exist yet, Sydney has a world-leading team of software engineers coding the apps that will run on them."
