The companies report a component-level measurement of 7 mdB, about a third of the roughly 20 mdB published in 2025. In photonic quantum computers, photon loss accumulates across switches.
An air-filled core lets light travel at a speed close to 300 thousand kilometres per second, and delay fell by about 30%. The test ran on a specially assembled line, not a live network.
Ring Rover Cam patrols premises on a set route or goes to alarms from other Ring devices; a charge lasts about 30 minutes.
Researchers calibrated a low-cost digital camera to read the infrared electroluminescence of silicon modules and derive open-circuit voltage; tested on eight modules built 1978–2022.
The EU programme splits €440 million in grants and €85 million for a digital platform; early-stage teams can apply for up to €100.000 for proof-of-concept prototypes.
Photon pairs from two independent gallium arsenide quantum dots were used for entanglement swapping in a laboratory setup, a step toward quantum repeaters. Fidelity reached 0.71 with time selection.
Intensity cycling added to transient scattering microscopy isolates single-particle transport in van der Waals semiconductors and tracks exciton–exciton annihilation in lab experiments.
Under the IMT-2020 (5G) Promotion Group, test terminals on the Qualcomm X105 modem were checked with ZTE network equipment in uplink and beam-management scenarios.
Tesla is studying a laser that clears only the windshield area in front of a self-driving camera; an updated patent was granted on 31 March.
A prototype speckle spectrometer built around an integrating sphere resolves 6 fm at 780 nm, about 80 times finer than earlier speckle devices, and measured rubidium hyperfine structure.
ZDNET Korea reports Samsung is developing hybrid-bonded 3D chip stacking with a pitch of about 6 μm, versus at least 25 μm for thermocompression bonding.
Hong Kong Polytechnic University researchers found that uneven charge losses between neighbouring grains speed up light ageing; an additive slowed it in small lab cells.
A spin-cast perovskite film conducts heat at about 0.04 W/(m·K) yet has a 7.7 GPa modulus, above most plastics, foams and aerogels. It is still a lab sample.
A flip-chip packaged gallium oxide module handled pulsed 1000 V, 1000 A switching, raising ultra-wide bandgap power capacity by over two orders of magnitude, the authors report.
A persistent 1-minute oscillation in grid frequency on several continents is linked to synchronized control software in UPS and battery storage. The amplitude has grown in several grids.
A single silicon photonic platform with a hybrid laser covered both short data-center-scale links and long-haul lines in an experimental demonstration.
Researchers filled the pores of a copper-based MOF with ionic liquid and etched it with a gallium ion beam, avoiding the cryogenic cooling previously required for such patterning.
A review of earlier lab work describes proteins, DNA and other biomaterials as light guides, emitters and converters; medical sensors look most promising, but integration is hard.
The dual-station tool handles 200 and 300 mm wafers, dicing lane widths down to 5 μm and thicknesses of 25–700 μm, according to the company.
Japan's Kirin Holdings sells a spoon that passes electric current to make low-sodium food taste saltier. It costs 24,750 yen and is sold only within Japan.
