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.

PsiQuantum today announces Omega, a quantum photonic chipset purpose-built for utility-scale quantum computing. Featured in a newly published paper in Nature, the chipset contains all the advanced components required to build million-qubit-scale quantum computers and deliver on the profoundly world-changing promise of this technology. Every photonic component is demonstrated with beyond-state-of-the-art performance. The paper shows high-fidelity qubit operations, and a simple, long-range chip-to-chip qubit interconnect – a key enabler to scale that has remained challenging for other technologies. The chips are made in a high-volume semiconductor fab, representing a new level of technical maturity and scale in a field that is often thought of as being confined to research labs. PsiQuantum will break ground this year on two datacenter-sized Quantum Compute Centers in Brisbane, Australia and Chicago, Illinois.

Quandela in consortium with attocube systems AG announce that they have been selected by EuroHPC Joint Undertaking and EuroQCS-France to deliver a universal photonic quantum computer, with at least 12 qubits, the most powerful in Europe. The system, owned by EuroHPC and co-acquired by GENCI, will be hosted and operated by CEA at TGCC. It will be coupled to the Joliot-Curie supercomputer, and will be made available to scientific communities in 2025 as part of open research.

Toshiba Corporation, a leading innovator in technologies realizing quantum key distribution (QKD) for secure network communications, has announced two significant advances in essential technologies for establishing global-scale quantum networks: Large-Scale Quantum Key Distribution Network Control Technology, and High-Speed Quantum Key Distribution Technology.

That’s exactly what Harvard physicists have done, using existing Boston-area telecommunication fiber, in a demonstration of the world’s longest fiber distance between two quantum memory nodes. Think of it as a simple, closed internet carrying a signal encoded not by classical bits like the existing internet, but by perfectly secure, individual particles of light.

MIT physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations that could generate the first purely magnetic quantum gate — a key building block for a new type of quantum computer.

Researchers from Jena, Würzburg and Potsdam have successfully developed a design for the smallest system of its kind so far to take highly secure quantum communication to space: Led by Fraunhofer IOF, the project CubEniK developed an ultracompact payload for a satellite the size of a shoe box, a so called “CubeSat”. The goal of the mini satellite is to transmit a secure quantum key over a distance of 300 kilometers between two ground stations in Jena and Munich.

LuxQuanta has been awarded with the Salvà i Campillo Award for Entrepreneurship at the 30th edition of La Nit de les Telecomunicacions i la Informàtica, one of the most prestigious annual events in Catalonia’s digital and telecommunications sectors.

Lightmatter has announced Passage M1000, a groundbreaking 3D Photonic Superchip designed for next-generation XPUs and switches. The Passage M1000 enables a record-breaking 114 Tbps total optical bandwidth for the most demanding AI infrastructure applications.

Lightmatter, the leader in photonic supercomputing, today announced it appointed Jason Zander to its board of directors. Zander joins as Lightmatter strengthens its foothold in powering the next generation of computing systems to accelerate AI innovation.
