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.

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 ...

In February 2025, scientists successfully teleported quantum information between two quantum computers six feet apart.

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

A new fault-tolerant architecture using 448 atomic qubits suppresses errors past the critical point needed for scaling.

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 ...

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