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.

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

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

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

Quantum computers will need large numbers of qubits to tackle challenging problems in physics, chemistry, and beyond. Unlike classical bits, qubits can exist in two states at once—a phenomenon called ...

Q3 2025 Management View CEO Subodh Kulkarni reported strong momentum in demand for on-premises quantum computers and highlighted expanding collaborations to advance research and the quantum ecosystem.

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 ...

Everyone in quantum computing agrees that error correction will be the key to doing a broad range of useful calculations. But early every company in the field seems ...
