A standard catalogue model: the dimensions, control package and finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and interface language can be adapted without a new design cycle.

01 / Overview

Quantum communication transmits secure signals through optical fibers, but only during the transmission process. Satellite ground communication requires precise alignment with satellites to address the challenges posed by high-speed satellite movement.

02 / How visitors use it

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

03 / The science behind it

Quantum communication is based on optical fibers and achieved through the transmission of optical signals. The high-precision optical path alignment technology between satellite and ground is used to establish high-precision laser links between the satellite and two ground stations simultaneously while the satellite is in high-speed motion.

04 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
