Light Chip Plays Quantum Pinball ⚡ экспресс
A 3D photonic chip with 128 reconfigurable optical channels is unveiled, capable of manipulating single photons. Using thermo-optic control, the chip performs large-scale quantum state transformations. With it, boson sampling (a task impossible for classical computers) was carried out on 4 photons from quantum dots, demonstrating random number generation. Agreement with theory confirmed the device’s reliability. Interestingly, boson sampling can be compared to the scattering of light in a tangled maze, where classical predictions are powerless.
A glass chip with 128 waveguides works like a quantum pinball machine. Instead of balls — photons, instead of flippers — microheaters that change routes on the fly. The task is simple: launch up to four identical particles and see where they end up. This puzzle, boson sampling, is beyond regular computers, so it became a test of quantum supremacy.
Scott Aaronson proposed it in 2011 as a paradox that could bypass supercomputers. The practical value is huge: the distribution of photons at the chip's output, Qolossus 3D, is genuinely random, not pseudo-random like in laptops. Such randomness is ideal for encryption — it can't be predicted.
Amazingly, the chip needs no bulky coolers: the quantum game runs at room temperature. Here, heat is not a hindrance but a tool.
🎯 Boson sampling resembles pinball, where even knowing all the settings, you can't predict the final position of the balls — no supercomputer can handle this task.
🎬 If in movies quantum computers crack codes, the Qolossus 3D chip does the opposite: it creates randomness that no hacker can break.
