Summarize this article with:
Welinq Releases Commercial Entangled Photon Pair Source Following First Sale Welinq has announced the commercial launch and initial sale of its rack-mounted Entangled Photon Pair Source. The first unit has been delivered to a leading European institution, marking the company’s second commercial hardware milestone following the previous deployment of its QDrive quantum memory. The system is designed to provide the underlying photonic infrastructure required for secure communications and the interconnection of disparate quantum processing units (QPUs). The source is engineered for integration into standard fiber-optic and data center environments, utilizing a 19-inch rack-mount form factor and designed for continuous room-temperature operation. It features narrowband emission with linewidths ranging from 2 to 20 MHz, specifically calibrated for interfacing with atomic-based quantum technologies. The device generates dual-wavelength entangled pairs: one photon is emitted in the telecom C-band for low-loss transmission over existing fiber networks, while the entangled partner is emitted at a visible wavelength optimized for coupling with atomic qubits. Technically, the source is designed for full-stack interoperability with Welinq’s quantum memory modules and its software suite for algorithm partitioning. This enables the establishment of on-premises quantum nodes capable of managing distributed entanglement across various quantum computing modalities. By providing both the entanglement source and the memory components as production-ready modules, the architecture facilitates the transition from laboratory-scale experiments to operational quantum networking for research and industrial applications.
