Despite challenges, quantum computing can break combination of blockchain and AI

Quantum computing can break the tough combination of blockchain and artificial intelligence (AI) together but it has challenges, an industry expert said.

Quantum computers, which have an immense computing power to encrypt and decrypt data, can crack even the most elaborate forms of encryption in use today and they can perform complex calculations at 100m times the speed of current computers.

What is quantum computing?

Data can be processed in an exclusive binary state at any point of time, that is, either 0 (off) or 1 (on) but in quantum computing, it can work in a two-way mode which means that it can change 0 into a superposition of 0 and 1.

 “For any technology, there is a way to break and quantum computing may make it easier for people to break the existing encryption technology.” Dr. Anand Rao, global AI lead at research and consulting firm PwC, told TechRadar Middle East.

If quantum computing becomes widely accessible, he said that everyone will be forced to upgrade from the current encryption to quantum encryption to stay one step ahead of professional hackers.

But will everyone adopt quantum computing, he said: “no”.

What is quantum encryption?

Quantum encryption, also known as quantum cryptography, uses a series of photons to transmit data from one location to another over a fibre optic cable. If the photon is read or copied in any way by a middle man, the state of the photon will change. The change will be detected by the endpoints and the transaction will not be…
