Quantum computers promise to solve problems far beyond the reach of today’s machines, but there is a stubborn obstacle ...

Physicists have invented a new type of analogue quantum computer that can tackle hard physics problems that the most powerful digital supercomputers cannot solve. New research published in Nature ...

It remains an open question when a commercial quantum computer will emerge that can outperform classical (non-quantum) machines in speed and energy efficiency while solving real-world combinatorial ...

Probably most people would agree with Gerry Rice (February 14) that children should not be deprived of computers but we should be realistic. Children have to learn many things about the external world ...

The potential of quantum computing has been hailed as revolutionary, able to change the way everything in our world works by finding solutions exponentially faster than today’s most powerful ...

ELECTRONIC computers can solve complex problems encountered in medical research. This was revealed at the second Annual Medical Symposium held recently in New York. So, 59 years ago, started a story ...

Kwabena Boahen’s love affair with digital computers began and ended in 1981, when he was 16. Boahen lived outside the city of Accra in the West African nation of Ghana. His family’s sprawling block ...

As a child of the 1990s, I couldn’t avoid the game-turned-best-seller Tetris. Launched in 1984 by Russian programmer Alexey Pajitnov, Tetris quickly became a blockbuster and has had hundreds of ...

Bees can solve complex mathematical problems which keep computers busy for days, research has shown. The tiny insects learn to fly the shortest possible route between flowers discovered in random ...

Scientists at Queen Mary, University of London and Royal Holloway, University of London have discovered that bees learn to fly the shortest possible route between flowers even if they discover the ...
