United Kingdom, Feb. 28 -- Amazon has entered the quantum computing race with a chip built on "cat qubit" technology.

The firm has become the third tech giant in recent months to make a breakthrough in quantum computing with its newly-unveiled prototype chip Ocelot that is powered by "cat qubit" technology - which takes its name from the 'Schrodinger's cat' though experiment.

The chip seeks to make quantum computers error free, which has proved to be the biggest stumbling block for the technology so far.

Amazon believes that the recent advancements could allow quantum computers to be usable earlier than previously thought, although how quickly the machines will be powerful enough before they are practically useful remains up for debate...
