Zero Wosatha Amafuna Kulondola Konse

Kampani ya Large Hadron Collider ya CERN imagwiritsa ntchito mtunda wa makilomita 12 kuchokera kuchitoliro chopangidwa ndi jekete la vacuumkuti ifalitse madzi a helium (-269°C) kudzera mu maginito a superconducting. Dongosolo la 0.05 W/m·K kutentha kwa mpweya—kotsika 50% kuposa mizere yokhazikika ya cryogenic—limaletsa kuzimitsa komwe kumawononga $500,000 pa chochitika chilichonse.

Kusintha kwa Cold kwa Quantum Computing

Purosesa ya quantum ya Sycamore 3.0 ya Google imagwiritsa ntchito mapaipi a cryogenic omwe amatetezedwa ndi vacuum kuti aziziritse ma qubits kufika pa 15 mK. Kapangidwe ka copper-MLI composite kamachepetsa kusagwirizana komwe kumachitika chifukwa cha kugwedezeka ndi 70%, zomwe zimapangitsa kuti zolakwika zikhale zosakwana 10⁻⁵—chinthu chofunikira kwambiri pamakina a quantum omwe angathe kukulitsidwa.

Kusunga Helium: Chofunika Kwambiri pa Zachuma

MIT ya 2024payipi yosinthasintha ya jekete la vacuumDongosololi limapezanso 94% ya helium coolant kudzera mu ma network a VIH otsekedwa, kuchepetsa ndalama zomwe zimagwiritsidwa ntchito pachaka kuchokera pa 2.8Mto2.8Mto400,000—chitsanzo cha kafukufuku wokhazikika wa sayansi ya fizikisi.
