Quantum computing CATASTROPHE? Quantum computing ‘poses security RISK’, warns expert

QUANTUM computing will irrevocably revolutionise our world with almost unimaginable benefits, but its sheer power also poses a dire risk to security, an expert has warned.

Computing power has advanced at a surprisingly regular rate since the 1970s.

Intel co-founder Gordon Moore predicted this back in 1965.

He gave his name to Moore’s law – the prophetic observation that the number of transistors in a dense integrated circuit doubles about every two years.

But these predictable improvements are set to grow exponentially once quantum computing goes live.

Quantum computing renders our classical securities essentially null and void

Dr Colin Wilmott said there are both benefits and dangers that near-infinite computational power presents, in contrast to current technologies – defined as “classical computing”.

He told “Quantum computing can certainly revolutionise society in a way that is positive for everybody.”

“It is designed to solve many problems; everything from designing medicines, to optimisation problems, to very sensitive measurement device and ensuring secure communication.

“Hacking for example is a big thing at the moment – quantum cryptography would rule it out.

“Quantum is 100 percent guaranteed by the laws of quantum mechanics.

“There is a great advantage there in terms of the speeds which quantum computing can offer.”

But there is a flip side to this unimaginable computing power – which Nottingham Trent University mathematician Dr Wilmott believes “render our classical securities essentially null and void.”

He said: “There are also disadvantages to using quantum computing, in terms of how they might impact current technologies.

“For example a lot of the security that underpins banking technologies is run using mathematics that requires access to very sophisticated high prime numbers.

“They are sophisticated in the sense that we don’t really know what they are.
