Aalto University physicists in Finland have set a new benchmark in quantum computing by achieving a record-breaking millisecond coherence in a transmon qubit — nearly doubling prior limits. This ...

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 ...

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 ...

Quantum computers hold great promise for exciting applications in the future, but for now they keep presenting physicists and engineers with a series of challenges and conundrums. One of them relates ...

Today’s quantum computers are fundamentally impractical. But with a more resilient qubit, scientists believe they can unlock the technology’s extraordinary potential. Soon, they hope to prove it.

Quantum engineers have now demonstrated a fully controllable three‑qubit register on a silicon photonic chip, turning a long‑promised idea into working hardware. By combining solid‑state spin defects ...

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 ...

Rigetti Computing achieved 99.5% two-qubit gate fidelity in its 36-qubit system, set to launch August 15, 2025. Rigetti Computing has announced a significant achievement in quantum computing, reaching ...
