Understanding the Bloch sphere is key in quantum computing, representing qubit states and their superpositions for clearer ...

Quantum computing uses quantum mechanics—the physics governing particles at atomic and subatomic scales—to process information in totally different ways from today’s digital computers. Instead of ...

For the past six years, Los Alamos National Laboratory has led the world in trying to understand one of the most frustrating barriers that faces variational quantum computing: the barren plateau.

A new debate in quantum physics is shaking the foundations of modern science. Tim Palmerargues that nature may not follow ...

Quantum computers are beginning to become powerful tools for studying some of the most fundamental forces in the universe – and some of the trickiest to understand. Two experiments have used them to ...
