Koi ka ʻAʻohe Loa i ka Pololei Loa

Hoʻohana ka Large Hadron Collider o CERN i 12 km opaipu ʻaʻahu vacuume hoʻohele i ka helium wai (-269°C) ma o nā magnet superconducting. ʻO ka conductivity wela o ka ʻōnaehana he 0.05 W/m·K—50% haʻahaʻa ma mua o nā laina cryogenic maʻamau—kāohi i nā quenching e uku ʻia he $500,000 no kēlā me kēia hanana.

ʻO ka hoʻokahuli anuanu o Quantum Computing

Hoʻohana ka mea hana quantum Sycamore 3.0 a Google i nā paipu cryogenic maʻamau i hoʻopaʻa ʻia i ka vacuum e hoʻomaʻalili i nā qubits i 15 mK. Hoʻemi ka hoʻolālā composite keleawe-MLI i ka decoherence i hoʻokomo ʻia e ka haʻalulu ma 70%, e hiki ai i nā helu hewa ma lalo o 10⁻⁵—he hanana koʻikoʻi no nā ʻōnaehana quantum scalable.

Mālama ʻana i ka Helium: He Pono Hoʻokele Waiwai

ʻO ka makahiki 2024 o MITpaipu palupalu ʻaʻahu hoʻomaʻemaʻeHoʻōla ka ʻōnaehana i 94% o ka helium coolant ma o nā pūnaewele VIH loop pani, e hōʻemi ana i nā kumukūʻai makahiki mai 2.8Mt a i 2.8Mt a i 400,000—he kumu hoʻohālike no ka noiʻi physics hoʻomau.
