I-Absolute Zero Ifuna Ukunemba Okuphelele

I-Large Hadron Collider ye-CERN isebenzisa amakhilomitha ayi-12ipayipi elinejakethi ye-vacuumukujikeleza i-helium ewuketshezi (-269°C) ngokusebenzisa omaginethi abaqhuba i-superconducting. Ukushisa kwesistimu okungu-0.05 W/m·K—okungaphansi ngo-50% kunemigqa ejwayelekile ye-cryogenic—kuvimbela ukucima okubiza u-$500,000 ngesigameko ngasinye.

I-Cold Revolution ye-Quantum Computing

Iprosesa ye-quantum ye-Sycamore 3.0 ye-Google isebenzisa amapayipi e-cryogenic afakwe i-vacuum ngokwezifiso ukuze apholise ama-qubits abe ngu-15 mK. Umklamo we-copper-MLI ohlanganisiwe wehlisa ukungalingani okubangelwa ukudlidliza ngo-70%, okwenza amazinga amaphutha angaphansi kuka-10⁻⁵—ingqophamlando yezinhlelo ze-quantum ezingalinganiswa.

Ukulondolozwa kweHelium: Okubalulekile Kwezomnotho

I-MIT ka-2024ipayipi eliguquguqukayo lejakethi ye-vacuumuhlelo lubuyisa u-94% we-helium coolant ngamanethiwekhi e-VIH avaliwe, lunciphisa izindleko zonyaka kusuka ku-2.8Mto2.8Mto400,000—imodeli yocwaningo lwefiziksi oluqhubekayo.
