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.

Hoboken, N.J. – September 20, 2026 -- Quantum Computing Inc. (Nasdaq: QUBT) will demonstrate, for the first time, a platform combining quantum key distribution (QKD) with hardware-based Quantum Identity Authentication (QIA) on a single system at ECOC Exhibition 2026, running September 21-23 at FYCMA in Málaga, Spain.

QCi merges encryption and authentication into one telecom-compatible architecture

At Booth #1436, the company will showcase high-dimensional QKD, direct entanglement verification, QIA and integrated key management combined in a single platform. Traditional QKD systems have faced barriers including scalability limits, operational complexity, high infrastructure costs and reliance on classical authentication methods, confining much of the technology to research settings rather than commercial deployment.
