Cambridge, Massachusetts – October 24, 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.
