The Entangled Web
Quantum physics can already make communications super-secure. But exploiting some of its strangest properties could take these networks to the next level.
A secure internet is far stranger, and more entangled, than you would think.
Quantum mechanics remains one of the most robust and puzzling fields of science. It is now set to make the first fundamental change in computing since Alan Turing’s code-breaking efforts in World War II. The strange nature of qubits requires a new approach to programming and algorithms. Yet the true potential of quantum computing will only be clear once the “Entangled Web” becomes as ordinary a miracle as the smartphone in your pocket.

To Understand One of the Most Important Paradigm Shifts Ever, We Need a Radical Change of Mind-Set
In contrast to classical physics, quantum theory – applied in physics, mechanics and biology – describes phenomena that are often counterintuitive to human thought. But the technology based on it will fundamentally change our world. Let’s start with some basics: Quantum mechanics defines the behavior of molecules, atoms and subatomic particles. For example, light can […]

Quantum Computing Gets Real
Quantum mechanics is turbocharging computing. What does it mean for your business? Quantum mechanics disrupted classical physics when, in the early 20th century, Niels Bohr first described the ways that atomic behavior diverges from the behavior of larger matter. When science journalist Julian Brown wrote Minds, Machines, and the Multiverse in 2000, quantum computing was […]
