I-Absolute Zero ifuna ukuchaneka ngokupheleleyo

I-Large Hadron Collider yaseCERN iqeshe iikhilomitha ezili-12 ukusuka apho.umbhobho ofakwe ijakethi ye-vacuumukujikeleza i-helium engamanzi (-269°C) ngeemagnethi eziqhuba i-superconducting. Ukuhanjiswa kobushushu benkqubo ye-0.05 W/m·K—ingaphantsi kwama-50% kunemigca eqhelekileyo ye-cryogenic—kuthintela ukucima okubiza i-$500,000 ngesiganeko ngasinye.

Uguquko olubandayo lweQuantum Computing

Iprosesa ye-quantum yeSycamore 3.0 kaGoogle isebenzisa imibhobho ye-cryogenic eyenziwe ngokwezifiso ye-vacuum-insulated ukuze ipholise ii-qubits ukuya kwi-15 mK. Uyilo lwe-copper-MLI oludibeneyo lunciphisa ukungafani kwe-vibration-induced decoherence nge-70%, okuvumela amazinga eempazamo angaphantsi kwe-10⁻⁵—isiganeko esibalulekileyo kwiinkqubo ze-quantum ezinokukhula.

Ukugcinwa kweHelium: Umthetho Obalulekileyo Kwezoqoqosho

I-MIT ka-2024ipayipi eguquguqukayo yejakethi ye-vacuumInkqubo ifumana i-94% ye-helium coolant ngokusebenzisa iinethiwekhi ze-VIH ezivaliweyo, inciphisa iindleko zonyaka ukusuka kwi-2.8M ukuya kwi-2.8M ukuya kwi-400,000—imodeli yophando lwefiziksi oluzinzileyo.
