Google says it has achieved ‘quantum supremacy’ with super computer that ‘can complete TEN THOUSAND years’ work in just three minutes’

Google claims to have made a quantum computing breakthrough with a processor that performs in minutes work that would take classical computers 10,000 years.
This demonstration of so-called ‘quantum supremacy’ over conventional computers has been a goal of computing research for decades.
The findings show that making computers faster is achievable in the real world and there are no ‘hidden physical law’ to stop this, the researchers said.
Quantum computing is a fledgling technology which uses the weird world of quantum physics to achieve vastly sped-up information processing.
Normal, ‘classical’ computers store data as so-called ‘bits’ that can either be a ‘0’ or a ‘1’. Quantum bits — qubits — instead can be both at once.
This allows groups of qubits in a quantum computer to store more data using less energy than a classical computer could using the same number of bits.
Such devices may one day revolutionise tasks that would take normal computers years, such as seeking new drugs and optimising city and transportation planning.
