Part one explained the physics of quantum computing. This piece explains the target — how bitcoin's encryption works, why a ...

Classical computing has operated as the fundamental power behind our digital world for many decades. Modern civilization relies on classical systems to operate smartphones and global financial ...

For quantum computers to change the game of computation, scientists need to show that the machines’ calculations are correct. Now, there’s hope. Google’s Willow quantum chip has achieved verifiable ...

Classical computers, on the other hand, seem to have a tougher time. In the worst circumstances, they must do the unwieldy work of computing probabilities for all possible output strings—all 2 100 of ...

Caltech professor of chemistry Sandeep Sharma and colleagues from IBM and the RIKEN Center for Computational Science in Japan are giving us a glimpse of the future of computing. The team has used ...

Physicist Peter P. Orth (left) and computer scientist Markus Bläser are collaborating on the QIAPO project with industry partners Infineon and BMW, as well as the quantum startup planqc, to explore ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

Quantum computers are shifting from lab curiosities into real machines that can already outperform classical systems on narrow tasks, and the stakes are no longer theoretical. The technology promises ...

World Quantum Day highlights the science behind technologies that already power your life and those that could reshape it ...
