Physicists continue to argue over Microsoft’s qubit claims. The entire field hangs in a delicate balance.

A quantum computer is also a kind of computing device, but instead of using a bit — a one or zero — it uses this thing called a qubit, or quantum bit. And the quantum bit has some additional ...

Get Instant Summarized Text (Gist) A 56-qubit quantum computer has achieved a significant milestone by generating certified random numbers, a task unattainable by classical computers. This process ...

Working at nanoscale dimensions, a team of scientists led by the Department of Energy's Oak Ridge National Laboratory revealed a new way to measure high-speed fluctuations in magnetic materials.

In 2019, Google's 53-qubit "Sycamore" processor completed a random circuit sampling task in 200 seconds, a task that would have taken approximately 10,000 years to simulate on the world’s ...

The biggest limitation of quantum computers is that they only contain, at max, around 1,000 qubits due to disruptions caused by noise that leads to decoherence. Microsoft set out years ago to develop ...

French quantum computing startup Alice & Bob SAS today announced a significant advancement in cat qubit technology to reduce errors in quantum computers. Named after the Schrödinger’s cat ...

Finnish quantum computing company IQM Quantum Computers has partnered with VTT Technical Research Centre of Finland to launch Europe’s first 50-qubit superconducting quantum computer. The system is ...

"The nitrogen-vacancy center functions as both a quantum bit, or qubit, and a highly sensitive sensor that we moved around on top of the thin film to measure temperature-dependent changes in ...
