KDDI Research, Inc. (“KDDI Research”), and Toshiba Digital Solutions Corporation (“Toshiba Digital Solutions”) have developed a multiplexing technology for quantum key distribution (QKD) that is theoretically impossible to eavesdrop. This technology assigns secret keys to the C-band and high-volume data signals to the O-band, enabling multiplexed transmission over a single optical fiber. Furthermore, utilizing this technology, we have successfully transmitted secret keys and high-capacity data signals at 33.4 Tbps over 80 km for the first time.

Thales Alenia Space, the joint venture between Thales (67%) and Leonardo (33%), and Hispasat, Redeia’s satellite services operator, have announced the start of the development, manufacturing, verification, and validation phase of the QKD-GEO prototype, Spain’s quantum key distribution system from geostationary orbit. With a budget of 103.5 million euros, the QKD-GEO mission is a project initiated by the Spanish Secretary of State for Telecommunications and Digital Infrastructures and funded by European funds from the Recovery, Transformation, and Resilience Plan (PERTE Aeroespacial), for which contracting is managed by CDTI.

Infleqtion today announced it has acquired two integrated silicon photonics companies: SiNoptiq Inc. and Morton Photonics Inc. These acquisitions enable Infleqtion to expedite plans for chip-scale integration of lasers and photonic and atomic systems, which is essential for commercializing quantum products, such as sensors and quantum computers, as well as bolstering the overall quantum supply chain and enabling quantum manufacturing at scale.

Yale researchers have figured out a better way to control the path of light on small chips, a breakthrough that could lead to better and cheaper sensors, smart phones, and other devices. Led by Prof. Peter Rakich, the results are published in Nature Photonics.

Scientists at EPFL and IBM Research have developed a compact optical amplifier based on a photonic chip that vastly outperforms traditional optical amplifiers in both bandwidth and efficiency. This breakthrough could reshape data center interconnects, AI accelerators, and high-performance computing.

AROBS Polska, part of the AROBS Group, an entrepreneurial technology company listed on the Bucharest Stock Exchange, has been selected by the European Space Agency (ESA) to develop and implement the Post-Quantum Cryptography Algorithms for Satellite Telecommunication Applications (PQC ASTrAL) project. This project carried out under the ESA Advanced Research in Telecommunications Systems (ARTES) Space Systems for Safety and Security (4S) program within ESA’s Connectivity and Secure Communications directorate, aims to develop a cryptographic key management system for satellites based on post-quantum algorithms, ensuring the protection of communications against emerging threats posed by quantum computers.

A collaboration bringing together UBC Blusson QMI researchers with industry and government partners is set to accelerate research and commercialization of innovative photonic chips. With over $1 million in funding from the Natural Sciences and Engineering Research Council of Canada (NSERC) and the National Research Council Canada (NRC), the project aims to overcome key integration challenges in embedding quantum light sources into semiconductor-based platforms.

Xairos Systems, Inc. (Xairos), a space-based quantum technology company, announces Joseph Campagna as the Chief Strategy Officer – a key leader with expertise not only in space, but also in photonics and laser communications, specifically relevant to Xairos’ quantum technology that leverages photon entanglement for a global timing service.

Xairos Systems, Inc. announces it has been selected by SpaceWERX for a Direct-to-Phase II contract, in the amount of $1.9M, focused on demonstrating a fusion PNT (position, navigation and timing) of quantum and optical synchronization of clock ensembles to address the most pressing challenges in the Department of the Air Force (DAF). Working with partners Luminous Cyber Corporation and Eritek Inc., the team recently completed Preliminary Design Review (PDR).
