XPRIZE has launched a global competition worth $5 million to develop practical quantum algorithms. The competition aims to accelerate the development of quantum computer applications that can solve important societal problems.
Google has built a quantum computer that makes fewer errors as it scales up. The company has passed an important threshold for error correction in quantum units. This paves the way for practically usable quantum computers in the future.
IBM's quantum computer successfully completes a 'benchmark' experiment. Researchers work around quantum noise to get reliable results. The achievement suggests quantum computers could have practical applications within two years.
