Researchers have used a quantum computer to simulate how matter can emerge from pure energy, a process linked to pair production in which energetic particles such as photons convert into particle-antiparticle pairs. The demonstration shows how quantum hardware can model fundamental physics processes that are extremely difficult to capture with classical computers, offering a new tool for studying high-energy phenomena.

French quantum computing company Quandela is looking to work with South Korean firms to manufacture its photonic quantum chips. The move would pair Quandela's light-based quantum processor technology with Korea's advanced semiconductor manufacturing base. Details on specific partners or timelines have not yet been announced.

Researchers report that hyperbolic wave attractors, structures that trap and concentrate light waves, could be used to build next-generation optical chips. By confining light more efficiently, the approach may improve photonic circuits used in computing and communications. Details of the research and its practical applications remain limited in the available reporting.

RoboTechnik completed its Hong Kong listing on September 29 and began trading on the Hong Kong Stock Exchange. The company, active in photonics and silicon automation for manufacturing, adds to the flow of semiconductor-related firms seeking listings in Hong Kong. The move gives the company access to public capital markets as demand for automation and chip manufacturing equipment remains strong.

Reports describe a single photon that traveled roughly 2 billion light-years before reaching Earth, a journey that current physics supposedly says should not have been possible. The claim is circulating widely, but no specific observatory, source event, or research team has been named, so the finding's details and significance remain unverified.

Researchers working under Optica's ultrafast laser research report that new laser techniques can reveal how materials respond to light down to the level of individual electrons. The advance gives scientists a more direct view of the electron dynamics that underpin light-matter interactions, with potential relevance for photonics, electronics and materials science, though detailed findings remain limited in available coverage.

LightCounting has published a roundup of highlights from CIOE 2026, the China International Optoelectronic Exposition. The recap covers developments showcased at the event, a key gathering for the optical communications and photonics industry. Industry watchers are looking to the show for signals on optical component and module trends.

Researchers report that a quantum Hall insulator can be used to link resonators so that signals travel in only one direction, a property known as nonreciprocal transmission. The approach exploits the topological edge states characteristic of the quantum Hall effect, which could prove useful for routing signals in photonic or microwave circuits without backward reflections or interference.

Xanadu Quantum Technologies, the Toronto-based photonic quantum computing company now trading under the ticker XNDU, is drawing attention as investors follow its share price, quotes and company news on financial platforms. The stock is being watched as part of broader interest in publicly listed quantum computing firms, where early-stage commercial timelines make valuations volatile and each company announcement or sector development can move prices noticeably.
