ThinkQuantum and University of Padua Demonstrate 18 km Free-Space QKD

Researchers at the University of Padua and ThinkQuantum have demonstrated intermodal quantum key distribution over an 18 km free-space link in northeastern Italy. Adaptive optics at a 410 mm urban telescope coupled the telecom-wavelength signal into single-mode fiber and produced secret keys at about 200 bit/s with room-temperature detectors. Link parameters, detector comparison, and network-design implications are covered here.

Photonic Publishes SHYPS QLDPC Logic Research in Nature Communications

Photonic Inc. announced that Nature Communications has published its paper on SHYPS QLDPC codes for efficient quantum logic and error correction. In simulated comparisons, the codes used about 2× to 3.5× fewer physical qubits than comparably scaled surface-code encodings. Circuit-level results, Clifford compilation details, and architecture implications are in the journal article.

Pasqal and Eleven Ventures Establish Joint Venture for Quantum Systems in Saudi Arabia

Pasqal and Eleven Ventures have agreed to form a commercial joint venture that will deploy multiple neutral-atom quantum computing systems inside Saudi Arabia and across the broader MENA region. The partnership also prioritizes building local talent so quantum capability is developed within the Kingdom rather than accessed remotely. Strategic leadership will be provided by HRH Prince Abdulaziz Bin Turki Bin Talal as Chairman of Pasqal Arabia, with further technical and commercial details available in the full announcement.

NIST Researchers Scale Superconducting Photon Detectors “Bigly”

NIST researchers have fabricated superconducting photon detectors measuring 0.1 mm—about 1,000 times wider than conventional nanowire designs. The architecture delivers a billion-fold reduction in dark counts while simplifying large-area fabrication. Technical details on current redistribution and application implications appear in the Optica paper and NIST release.
