Computers that exploit the weird rules of quantum mechanics may soon crack problems that are unsolvable using existing technology. Today’s machines are still far from achieving that, but the ...

Quantum physics underlies technologies from the laser to the smartphone. The International Year of Quantum marks a century of scientific developments.

Yet, quantum mechanics is far from complete. Despite its success in explaining a wide range of phenomena, questions remain. The nature of dark matter, the integration of gravity into quantum theory, ...
