Insider Brief NIST researchers and collaborators demonstrated the transmission of entangled photons through 62 kilometers of existing above-ground fiber infrastructure, supporting research into practical quantum networks. The team used real-time polarization stabilization technology developed by […]
Insider Brief DARPA has launched the “It’s About Time” program to establish a pilot manufacturing pipeline for optical clocks. The initiative builds on DARPA’s ROCkN and OASIC programs, which advanced compact optical clocks while developing […]
Insider Brief Xanadu reported higher year-over-year second-quarter revenue while increasing investment in photonic quantum computing research, manufacturing and U.S. expansion, ending the quarter with $312.8 million in cash. The company expanded photonic chip manufacturing, reported […]
Guest Post by Michael Osei, M.Sc. in Physics. Press release – Quantum technology can sound like science fiction: computers that solve problems beyond the reach of today’s machines, sensors that detect the almost undetectable, and […]
By combining the long-range connectivity of photonic qubits with near-deterministic entanglement mediated by cavity-coupled atoms, Quantum Source’s new blueprint lays out a concrete, quantitative path toward practical fault-tolerant quantum computing. Insider Brief Quantum Source has […]
Insider Brief IonQ’s subsidiary Capella has received a contract under the National Reconnaissance Office’s Radar Commercial Augmentation program to provide commercial synthetic aperture radar imagery and data services. The agreement will support U.S. national security […]
An international team of researchers has succeeded in producing atomic quantum gas mixtures with an unprecedented particle flux. In the journal Nature Communications, the scientists report on experiments conducted with the MAIUS-B apparatus, in which […]
Super-thin superconducting materials, which are only one or a few atoms thick, have unique properties scientists can leverage to produce more compact, scalable, and efficient quantum devices. But these fragile materials degrade so rapidly in […]
Insider Brief IonQ reported record second-quarter revenue of $80.1 million, up 287% year over year, and raised its full-year 2026 revenue guidance to $280 million to $290 million while reaffirming expectations for 100% organic revenue […]
