I-Absolute Zero Ifuna Ukunemba Okuphelele

I-CERN's Large Hadron Collider isebenzisa u-12 km weipayipi le-vacuum jacketedukuzungeza i-helium ewuketshezi (-269°C) ngozibuthe abakhulu. I-thermal conductivity yesistimu engu-0.05 W/m·K—amaphesenti angu-50 aphansi kunemigqa evamile ye-cryogenic—ivimbela ukucisha okubiza u-$500,000 ngesigameko ngasinye.

I-Quantum Computing's Cold Revolution

Iphrosesa ye-Sycamore 3.0 ye-quantum ye-Google isebenzisa amapayipi e-vacuum-insulated cryogenic angokwezifiso ukupholisa ama-qubits kuya ku-15 mK. Idizayini eyinhlanganisela ye-copper-MLI yehlisa ukungezwani okubangelwa ukudlidliza ngo-70%, ivumela amazinga ephutha angaphansi kuka-10⁻⁵—ingqopha-mlando yezinhlelo ze-quantum ezingakala.

Ukongiwa kwe-Helium: Okubalulekile Kwezomnotho

I-MIT ka-2024i-vacuum-jacket hose eguquguqukayouhlelo lubuyisa u-94% we-helium coolant ngokusebenzisa amanethiwekhi e-VIH avaliwe, inciphisa izindleko zonyaka zisuka ku-2.8Mto2.8Mto400,000—imodeli yocwaningo oluqhubekayo lwe-physics.
