Koi Pono ʻo Zero Absolute

Hoʻohana ka CERN's Large Hadron Collider i 12 km opaipu ʻaʻahu ʻaʻahue kaapuni i ka helium wai (-269°C) ma o ka superconducting magnets. ʻO ka 0.05 W/m·K thermal conductivity o ka ʻōnaehana—50% haʻahaʻa ma mua o nā laina cryogenic maʻamau-pale i nā kinai i kūʻai ʻia he $500,000 no kēlā me kēia hanana.

ʻO Quantum Computing's Cold Revolution

Hoʻohana ka Google's Sycamore 3.0 quantum processor i nā paipu cryogenic i hoʻopaʻa ʻia i ka vacuum-insulated maʻamau e hoʻomaha i nā qubits i 15 mK. ʻO ka hoʻolālā copper-MLI composite e hōʻemi ana i ka decoherence i hoʻokomo ʻia i ka vibration e 70%, e hiki ai i nā helu kuhi ma lalo o 10⁻⁵—he milestone no nā ʻōnaehana quantum scalable.

Helium Conservation: He Pono Hoʻokele waiwai

ʻO MIT ka makahiki 2024hose hikiwawe i ka vacuum-jacketHoʻihoʻi ka ʻōnaehana i ka 94% o ka mea hoʻoheheʻe helium ma o nā pūnaewele VIH i pani ʻia, e hōʻemi ana i nā kumukūʻai makahiki mai 2.8Mto2.8Mto400,000—he kumu hoʻohālike no ka noiʻi physics hoʻomau.
