- 1China's CanSemi draws record demand ahead of debut▼Betting on light: why China’s CanSemi is drawing record demand ahead of debut
CanSemi, a Chinese photonics-focused chipmaker, is attracting record investor demand ahead of its market debut, according to the South China Morning Post. The company, which works with silicon photonics technology used in optical communications, has drawn unusually strong interest in its listing, reflecting continued investor appetite for China's domestic semiconductor sector despite broader market uncertainty.
- 2Quantum memory stores single photons for record time▼Quantum memory stores single photons for record time in major leap towards a quantum internet
Researchers report a quantum memory that has stored single photons for a record length of time, a result described as a major step towards building a quantum internet. Long-lived storage of individual light particles is a key requirement for quantum repeaters, the devices needed to send entangled signals across continental distances. The achievement is drawing attention as a milestone in quantum communication research.
- 3Scientists Simulate Matter Emerging From Pure Energy On Quantum Computer●Scientists Simulated How Matter Can Emerge From Pure Energy On A Quantum Computer
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.

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.
- 5Photon Travels 2 Billion Light-Years Despite Physics Saying It Shouldn't▼A photon crossed 2 billion light-years to reach Earth when physics says it shouldn’t
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.
- 6Ultrafast Lasers Track Material Light Response at Electron Level●Optica Ultrafast Lasers Reveal Material Light Response Down To The Electron
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.
