Zero Mtheradi Imafuna Kulondola Kwambiri

Cern's Large Hadron Collider amagwiritsa ntchito 12 km kuchokeravacuum jekete chitolirokuti azizungulira madzi a helium (-269°C) kudzera mu maginito amphamvu kwambiri. Dongosolo la 0.05 W/m·K matenthedwe matenthedwe—50% kutsika kuposa mizere wamba ya cryogenic—amateteza kuzimitsa komwe kumawononga $500,000 pa chochitika chilichonse.

Quantum Computing's Cold Revolution

Purosesa ya Google ya Sycamore 3.0 quantum imagwiritsa ntchito mapaipi a vacuum-insulated cryogenic kuti aziziziritsa ma qubits mpaka 15 mK. Mapangidwe a copper-MLI amachepetsa kugwedezeka koyambitsa kugwedezeka ndi 70%, zomwe zimapangitsa kuti zolakwika zikhale pansi pa 10⁻⁵-chinthu chofunika kwambiri cha machitidwe a scalable quantum.

Kusunga Helium: Chofunika Kwambiri Pazachuma
