Following up on Microsoft’s announcement of a qubit based on completely new physics, Amazon is publishing a paper describing a very different take on quantum computing hardware. The system mixes two ...

In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions. “The real challenge, the thing that ...

A cryostat from a quantum computer stands during a press tour of the Leibniz Computing Center in 2022. Qubit is a key term in one of the most buzzy areas of technology: quantum computing. Qubits are ...

BERKELEY, Calif.,– Quantum-classical computing company Rigetti announced the launch of its flagship 84-qubit Ankaa-3 system featuring a hardware redesign. Rigetti ...

Qubits, the heart of quantum computers, can change performance in fractions of a second — but until now, scientists couldn’t see it happening. Researchers at NBI have built a real-time monitoring ...

A Canadian quantum computing start-up claims its new qubit will enable much smaller and cheaper error-free quantum computers. But getting there will be a steep challenge. To correct its own errors, a ...

Ankaa-3 features a broad hardware redesign enabling superior performance. Enhancements across the technology stack include a new cryogenic hardware design, an overhaul of the qubit circuit layout, ...

Russia has quietly vaulted into the front rank of quantum powers with a neutral-atom machine that combines a 72-qubit scale with 94% accuracy on two-qubit logic gates. The prototype, built under the ...

Figure 1 Schematic diagrams of two superconducting flux qubit circuits. The conventional qubit (a) requires an external magnetic field to operate optimally, while the new flux qubit (b), using a ...

Kawasaki and Wako, Japan, April 22, 2025 — Fujitsu Limited and RIKEN announced the development of a 256-qubit superconducting quantum computer, established at the RIKEN RQC-FUJITSU Collaboration ...
