Introduction Envision our digital world as a sprawling universe filled with glittering constellations of encrypted data, each packet of information ...

The breakthrough addresses concerns that powerful quantum computers could eventually crack encryption standards to leave vulnerable financial systems, government communications, health data and media.

What is it about quantum computers that makes them more powerful than conventional machines? A new experiment shows that the property of “quantum contextuality” may be a key ingredient. Quantum ...

Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...

International Business Machines Corporation IBM continues to push the boundaries of quantum technology to explore solutions to complex problems beyond the reach of classical computing. The company has ...
