Welinq, a leader in quantum networking technology, has launched the first commercial quantum memory designed specifically for quantum data centers with world-record performance. Quantum computing is reaching a turning point: with more than 100 individual quantum computers deployed in dedicated infrastructures, the next challenge is networking them into scalable, high-performance architectures.

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.

A research team at the Department of Energy’s Oak Ridge National Laboratory created a novel advanced microscopy tool to “write” with atoms, placing those atoms exactly where they are needed to give a material new properties.

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.

The group of CQT Principal Investigator Gao Weibo and their collaborators are the first to achieve near-unity quantum efficiency in 2D single photon emitters.

onQ, a leader in the quantum computing industry, today announced it has generated photons entangled with ions repeatedly and reproducibly, creating a quantum state which allows future quantum systems to communicate and transfer information between each other.

HRL Laboratories and Boeing have completed construction and technical validation on a quantum communication subassembly for Boeing’s Q4S satellite mission – a first-of-its-kind effort to demonstrate four-photon quantum entanglement swapping in space. This powerful capability is essential to enabling future secure communications and distributed quantum networks.

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.

Research teams led by Prof. PAN Jianwei, LU Chaoyang, HU Yongheng, and others have realized a high-performance single-photon source with an efficiency beyond the scalable linear optical quantum computing loss tolerance threshold for the first time, and the comprehensive indicators have reached the international advanced level. The results were published in Nature Photonics on February 28th.
