Today, IonQ announced that it has reached a definitive agreement with each of SK Telecom and ID Quantique (IDQ), a global leader in quantum safe networking and sensing headquartered in Geneva, Switzerland with offices in Seoul (South Korea), Vienna (Austria), and Boston (USA), to acquire a controlling stake in IDQ. Alongside the transaction, IonQ expects to enter into a strategic partnership focused on quantum with SK Telecom, the largest wireless telecommunications operator in South Korea.

ID Quantique (IDQ) is proud to announce it is partnering with ORCA Computing, a leader in quantum computing, to incorporate IDQ’s breakthrough single-photon detection technology in ORCA’s newest PT-2 photonic quantum computing system.

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.

An international team from LMU, Harvard University and the Institute of Materials Science in Japan has successfully demonstrated the detection of individual photons in the infrared spectrum by utilizing a revolutionary material called magic-angle twisted bilayer graphene. This discovery represents a significant step towards extending superconducting single-photon detection to longer-wavelength photons. The results are featured in Science Advances.

Researchers from ID Quantique and the University of Geneva have made a significant advancement in superconducting nanowire single-photon detector (SNSPD) technology. A new 28-pixel parallel SNSPD (P-SNSPD) combines state-of-the-art photon-number resolution (PNR) and ultra-high-speed performance.

Diamonds with certain optically active defects can be used as highly sensitive sensors or qubits for quantum computers, where the quantum information is stored in the electron spin state of these colour centres. However, the spin states have to be read out optically, which is often experimentally complex. Now, a team at HZB has developed an elegant method using a photo voltage to detect the individual and local spin states of these defects. This could lead to a much more compact design of quantum sensors.

Single Quantum is proud to announce the expansion of its operations with the opening of Single Quantum Germany, a new office based in Stuttgart, one of Europe’s foremost centers for quantum research and technology. This move represents a significant step in their continued growth and commitment to providing world-class single photon detection solutions to both their current and future customers.

Bluefors today announced a new, compact, high-performance, two-stage pulse tube cryocooler – the Cryomech PT205 – designed to support advanced scientific applications and superconducting technologies.

The Quantum Economic Development Consortium (QED-C) today announced the results of a research and development (R&D) program that focused on using cryogenic technologies to advance innovation in quantum technology.

Penn and CUNY researchers collaborated to develop a device that uses quantum principles to relay information securely—an advance that could improve encryption in critical service areas like banking and health care.
