Qubits differ from classical bits, which are coded as only 0 or 1. A qubit can be a combination of both 0 and 1 simultaneously. One way to think of it is as a coin spinning between a 0 and a 1 axis.

This fragility has been a formidable roadblock because the very properties that make quantum computers so powerful also make ...

Quantum computers have the potential to solve certain calculations exponentially faster than a classic computer could, but more research is desperately needed to make their practical use a reality.

For years quantum technology seemed exciting in theory but not much good in practice. Now the ability to combine qubits—bits ...

The dream of creating game-changing quantum computers—supermachines that encode information in single atoms rather than ...

Qubits, or quantum bits, are the fundamental units of information in quantum computing. Unlike classical bits, which can only exist in one of two states (0 or 1), qubits can exist in multiple states ...

IBM announced on Wednesday it has built a new experimental quantum computing chip called Loon that demonstrates it hit a key ...

Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions, marking a ...

A research team at the Jülich Supercomputing Center, together with experts from NVIDIA, has set a new record in quantum ...
