Spinning quantum dots

The name 'quantum dots' is given to particles of semiconducting materials that are so tiny—a few nanometres in diameter—that they no longer behave quite like ordinary, macroscopic matter. Thanks to their quantum-like ...

Building single-atom qubits under a microscope

Our team at IBM Research made a breakthrough in controlling the quantum behavior of individual atoms, demonstrating a versatile new building block for quantum computation.

Pushing quantum photonics

Quantum computers use the fundamentals of quantum mechanics to potentially speed up the process of solving complex computations. Suppose you need to perform the task of searching for a specific number in a phone book. A classical ...
