Cambridge, Massachusetts – October 26, 2026 -- Harvard University researchers reported control of more than 3,000 neutral atom qubits, one of the largest experimental quantum systems to date, in a paper published in Physical Review Letters.

The work demonstrates long-coherence control and advances the pursuit of fault-tolerant quantum architectures.

Kiutra closes €13 million Series A to remove helium-3 from quantum cooling

Garching-based Kiutra closed a €13 million Series A round on September 30. The startup builds cryogenic cooling systems for quantum computers that operate without helium-3, which the source describes as one of the most critical bottlenecks in scaling quantum hardware.

Kawasaki, Japan – September 11, 2026 -- Fujitsu has developed the world's first working prototype of a diamond-spin quantum computer that integrates tin-vacancy (SnV) centers into photonic integrated circuits, a milestone the company says advances the path toward scalable quantum systems.

Prototype runs at -271.6°C, warmer than superconducting rivals

The device operates at -271.6°C, a higher temperature threshold than the -273.13°C required by typical superconducting quantum computers. Fujitsu demonstrated in a test environment that the prototype can be operated via its Hybrid Quantum Computing Platform without requiring specialist quantum expertise, a factor that could lower operational barriers for enterprise adopters.
