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.
Pasqal has demonstrated trapping of individual rubidium atoms using laser light delivered and controlled by a photonic integrated circuit, which the company describes as a first for neutral-atom systems. The four independently addressable traps achieved atom lifetimes in line with existing bulk-optics platforms. Pasqal estimates the architecture can shrink optical hardware by up to 50 times en route to systems exceeding 10,000 atoms and 100 logical qubits.
SAXON Q has opened commercial orders for its SXQ128 and SXQ512 quantum computers, listed with aggregate qubit counts of 128 and 512. The company describes the systems as the first diamond-based NV-center machines to exceed 10 qubits. They operate at room temperature and eliminate cryogenic infrastructure while relying on standard photonics and control hardware. A proprietary multi-core operating system coordinates locally entangled qubits within each core (eight on the SXQ128, 16 on the SXQ512). The SXQ128 is available for delivery within three months; the SXQ512 begins deliveries in Q2 2027.
QuiX Quantum has announced commercial availability of Alquor 2.0, its next-generation rack-mountable photonic quantum processor platform offered in 8-mode, 20-mode, and 32-mode configurations.
QTREX Quantum Ltd. announced that its proprietary printed coaxial quantum interconnect platform exceeded RF performance requirements set by strategic partners. Characterization confirmed continuous broadband transmission from 10 MHz to 20 GHz, minimum 68 dB isolation, 4.4 picosecond average channel-to-channel skew, and high manufacturing consistency. The results validate the Additively Manufactured Electronics platform for commercial application development in dense quantum computing systems and are expected to advance existing strategic engagements.
The Pittsburgh Supercomputing Center, HPE, and Rigetti Computing will construct TangleLab, a hybrid quantum-classical supercomputing testbed funded by a $5 million NSF grant. The system integrates a 9-qubit Rigetti Novera QPU with HPE classical HPC hardware. Construction begins September 1, 2026, with operations expected in 2027. The testbed supports research, education, and hybrid workflow development.
Hangzhou-based Heguang Quantum has announced completion of a seed round and reported progress toward deterministic generation of photonic Gottesman-Kitaev-Preskill error correction codes. The company describes a proprietary pluggable nonlinear module intended to address probabilistic preparation barriers. Reported to be founded by Dr. Shang Yu, who trained under Academician Guo Guangcan, Heguang emphasizes modular distributed photonic systems and plans 2027 sales of its HQ10 quantum accelerator for hybrid classical-quantum use.
The EuroHPC JU has launched procurement for MeluXina-Q, a quantum computer to be hosted by LuxProvide in Luxembourg and integrated with the MeluXina supercomputer. The system will start with at least 10 semiconductor spin qubits and is planned to scale beyond 80 physical qubits. Acquisition is budgeted at up to €11.95 million ($13.6 million USD), co-financed equally by the EuroHPC JU and the Luxembourg Government. Once deployed, MeluXina-Q will support hybrid classical-quantum workflows for scientific, industrial, and public-sector users across Europe.
BTQ Technologies announced its subsidiary, QPerfect, is collaborating with the University of Strasbourg to support aQCess, France’s first public neutral-atom quantum computing platform. QPerfect will deliver a hardware-accurate digital twin of the processor using its MIMIQ simulation platform. The aQCess system targets more than 400 ytterbium-based qubits with Rydberg interactions and is designed for open access by researchers and industry. The partnership places advanced software tools in direct contact with scaling European quantum hardware.
