Google has unveiled a new chip which it claims takes five minutes to solve a problem that would currently take the world’s fastest super computers ten septillion – or 10,000,000,000,000,000,000,000,000 years – to complete.

The chip is the latest development in a field known as quantum computing – which is attempting to use the principles of particle physics to create a new type of mind-bogglingly powerful computer.

Google says its new quantum chip, dubbed “Willow”, incorporates key “breakthroughs” and “paves the way to a useful, large-scale quantum computer.”

However experts say Willow is, for now, a largely experimental device, meaning a quantum computer powerful enough to solve a wide range of real-world problems is still years – and billions of dollars – away.

Reinforcement learning – where the machines are taught to mimic humans – is how AI is trained.

It aims to make the robots less robotic, and more multi skilled.

BBC’s Lara Lewington has gone to the world leading MIT computer science and artificial intelligence lab to teach the robots so they can behave as humanly as possible.

The oceans have hit their hottest ever recorded temperature as they soak up warmth from climate change.

The average daily global sea surface temperature beat a 2016 record this week, according to the EU’s climate change service Copernicus.

It reached 20.96C. That’s far above the average for this time of year.

Oceans are a vital climate regulator. They soak up heat, produce half Earth’s oxygen and drive weather patterns.

The diplomatic red carpet was rolled out for a state visit from the Emir of Qatar, with the King and the Prince and Princess of Wales leading a royal welcome.

Prime Minister Keir Starmer also welcomed Qatar’s emir, Sheikh Tamim bin Hamad Al Thani, for a state visit to Britain on Tuesday that the prime minister hopes will help build on the Gulf state’s investment in the country.

The emir and wife Sheikha Jawaher bint Hamad bin Suhaim Al Thani arrived at Horse Guards Parade in London with Prince William and his wife Kate, who was marking her return to formal state visit duties after undergoing preventative chemotherapy for cancer.
