Princeton researchers have created a superconducting qubit that stays stable more than three times longer than previous designs, marking a major leap toward practical quantum computers.

Built from a single erbium atom, a hybrid quantum bit encodes data magnetically and beams it through fiber-optic wavelengths.

Quantum computers, which operate leveraging effects rooted in quantum mechanics, have the potential of tackling some ...

A new molecular qubit works with standard fibre-optic networks, advancing efforts to build a quantum internet offering ...

A Princeton team built a new tantalum-silicon qubit that survives for over a millisecond, far surpassing today’s best devices ...

NTT and OptQC aim to build a 1-million qubit quantum computer built on light-based photonics principles (rather than electricity) to enhance the reliability, scalability and practicality of the ...

Keeping a qubit stable is difficult enough, even in an ideal environment. Now, researchers have figured out how to make a protein behave like a qubit in a living cell. Fluorescent proteins were used ...

In addition to launching Nighthawk, IBM also announced its Quantum Loon chip, an experimental processor that will not be made ...
