Hawthorn Photonics (US) develops with quantum AdvR, Inc. name change.

Hawthorn Photonics is streamlining its brand portfolio by rebranding AdvR products as Covesion, establishing the latter as its dedicated components brand. The move accompanies a full corporate identity overhaul, with AdvR, Inc. becoming Hawthorn Photonics (US), Inc. and similar changes planned for its UK and Spanish entities. Radiantis will continue as the group’s systems brand for broadly tunable and frequency locked laser systems. AdvR Rebranding Establishes Covesion as Components Brand Covesion’s specialization in magnesium oxide-doped lithium niobate (MgO:LN) crystals and locked laser systems positions it as a key supplier for rapidly developing fields like quantum light source development and cold-atom sensor technology. Founded in 2007 and headquartered in Southampton, United Kingdom, Covesion previously operated as a distinct entity but now fully integrates as the components division of the larger photonics group, benefiting from shared resources and a streamlined operational structure. This move follows a period of growth for Covesion, including its support of sea trials for the HARLEQUIN quantum-hybrid inertial navigation system in November 2025, utilizing its LL2-Rb locked laser system aboard the Trinity House vessel THV Galatea. According to Mike Day, President of Hawthorn Photonics, transitioning AdvR to the Covesion brand creates a clearer identity for its components offering while maintaining the same products, people, and technical expertise customers know and trust. UKRI records demonstrate Covesion’s long-standing involvement in quantum projects, including the BLINQ project focused on blue laser integration with networked quantum memories and the QWISPS single-photon source waveguide projects spanning 2015 to 2017, the company says. The company’s expertise in manufacturing MgO:PPLN devices for efficient non-linear wavelength conversion, covering wavelengths from 390nm to 6μm, underpins its ability to serve diverse sectors including medical, aerospace, and scientific research, ensuring continued support for existing customers and expansion into new markets.

Tags: Ivy Delaney Ivy Delaney has been working with neural networks and machine learning since the mid-nineties, back when a couple of hidden layers and a long afternoon of training counted as ambitious. She has watched the field go from academic curiosity to the thing quietly running underneath everything, and she brings that long view to quantum computing.

For Quantum Zeitgeist she covers the ground where the two fields meet. That means quantum machine learning and the variational algorithms it leans on, and it also means the less glamorous but more interesting story of classical machine learning already doing real work inside quantum machines, decoding error-correcting codes, calibrating noisy hardware and learning the error models that simulators depend on. She writes about the hardware those algorithms have to run on too, and about the post-quantum cryptography scramble that the same hardware has set off. Her stories typically start with the paper, whether that is peer-reviewed work, conference proceedings or an arXiv preprint, with the source linked so you can hold a claim up against the research it came from. She is unimpressed by benchmarks that will not say what they beat, and by demonstrations that only work in the press release.
