Ma nā kahua ʻokiʻoki e like me ka hana semiconductor a me ke ana ʻana i ka quantum precision, kahi mea koʻikoʻi i nā kaiapuni electromagnetic, ʻo ka liʻiliʻi liʻiliʻi o ka electromagnetic disturbance i nā mea hana hiki ke hoʻololi i ka precision deviations, e pili ana i ka maikaʻi o ka huahana hope a me nā hopena hoʻokolohua. Ma ke ʻano he ʻāpana koʻikoʻi e kākoʻo ana i nā lako kikoʻī, ua lilo nā hiʻohiʻona magnetic susceptibility o nā paepae precision granite i mea nui i ka hōʻoia ʻana i ka hana paʻa o nā mea hana. ʻO ka ʻimi hohonu ʻana o ka hoʻokō ʻana i ka manaʻo o ka granite precision platform e hoʻomaopopo i ko lākou waiwai hiki ʻole ke hoʻololi ʻia i ka hana kiʻekiʻe a me nā hiʻohiʻona noiʻi ʻepekema. ʻO Granite ka mea nui i nā minerale e like me ka quartz, feldspar a me ka mica. ʻO ke ʻano uila o kēia mau kristal mineral e hoʻoholo i nā hiʻohiʻona maʻalahi o ka granite. Mai kahi hiʻohiʻona microscopic, i loko o nā minelala e like me ka quartz (SiO_2) a me ka feldspar (e like me ka potassium feldspar (KAlSi_3O_8)), ʻo ka hapa nui o nā electrons e noho pālua ana i loko o nā paʻa covalent a ionic paha. Wahi a ke kumu hoʻokuʻu ʻia ʻo Pauli i loko o ka mechanics quantum, ʻokoʻa nā ʻōkuhi o nā electrons i hoʻopaʻa ʻia, a ʻo kā lākou mau manawa magnetic e hoʻopau i kekahi i kekahi, e hoʻonāwaliwali loa i ka pane holoʻokoʻa o ka mineral i ke kahua magnetic waho. No laila, ʻo ka granite kahi mea diamagnetic maʻamau me ka haʻahaʻa haʻahaʻa haʻahaʻa loa, ma kahi o ke kauoha o \(-10^{-5}\), a aneane hiki ke nānā ʻole ʻia. Hoʻohālikelike ʻia me nā mea metala, ʻoi aku ka nui o ka pōmaikaʻi o ka granite. ʻO ka hapa nui o nā mea metala e like me ke kila he mau mea ferromagnetic a paramagnetic paha, me ka nui o nā electrons i hui ʻole ʻia i loko. Hiki i nā manawa wiliwili o kēia mau electrons ke hiki wawe ke Orient a hoʻolike ma lalo o ka hana a ke kahua mākēneki o waho, e hopena i ka hiki ke hoʻopalike ʻia o nā mea metala kiʻekiʻe e like me ke kauoha o \(10^2-10^6\). Ke loaʻa nā hōʻailona electromagnetic mai waho, e hoʻopili ikaika nā mea metala me ka māla magnetic, e hoʻohua ana i nā ʻōhua electromagnetic eddy a me nā poho hysteresis, kahi e hoʻopilikia ai i ka hana maʻamau o nā mea uila i loko o ka lako. ʻO nā paepae kikoʻī Granite, me kā lākou haʻahaʻa haʻahaʻa haʻahaʻa, ʻaʻole hiki ke launa pū me nā māla magnetic o waho, me ka pale ʻana i ka hana o ka hoʻopili electromagnetic a me ka hoʻokumu ʻana i kahi kaiapuni hana paʻa no nā mea hana pololei. Ma nā noi kūpono, ʻo ke ʻano haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o nā paepae precision granite ke kuleana nui. Ma nā ʻōnaehana kamepiula quantum, ʻoi aku ka maʻalahi o nā qubits superconducting i ka walaʻau electromagnetic. ʻO ka hoʻololi ʻana o ke kahua magnetic o ka pae 1nT (nanotesla) hiki ke kumu i ka nalowale o ka coherence o nā qubits, e alakaʻi ana i nā hewa helu. Ma hope o ka hoʻololi ʻana o kekahi hui noiʻi i ka paepae hoʻokolohua me nā mea granite, ua hāʻule nui ke kani ʻana o ke kahua magnetic a puni ka mea hana mai 5nT a i lalo o 0.1nT. Ua hoʻonui ʻia ka manawa coherence o nā qubits i ʻekolu mau manawa, a ua hōʻemi ʻia ka helu hewa o ka hana e 80%, e hoʻonui nui ana i ka paʻa a me ka pololei o ka helu helu quantum. Ma ke kahua o nā lako lithography semiconductor, ʻo ke kumu kukui ultraviolet kiʻekiʻe a me nā ʻike kikoʻī i ka wā o ke kaʻina lithography he koi koʻikoʻi no ke kaiapuni electromagnetic. Ma hope o ka hoʻohana ʻana i ka papa hana granite precision, ua pale pono nā mea hana i ka hoʻopili electromagnetic waho, a ua hoʻomaikaʻi ʻia ka pololei o ke kūlana mai ± 10nm a ± 3nm, e hāʻawi ana i kahi hōʻoia paʻa no ka hana paʻa o nā kaʻina hana holomua o 7nm a ma lalo. Eia kekahi, i nā microscopes electron precision kiʻekiʻe, nā mea hana nuklea magnetic resonance imaging a me nā mea hana ʻē aʻe i maʻalahi i nā kaiapuni electromagnetic, ʻo nā paepae precision granite e hōʻoiaʻiʻo e hiki i nā mea hana ke hana maikaʻi loa ma muli o ko lākou mau hiʻohiʻona haʻahaʻa magnetic susceptibility. ʻO ka ʻaneʻane ʻaneʻane ʻaʻole hiki ke hoʻopaʻa ʻia o nā papa hana granite precision i koho maikaʻi loa ia no nā lako kikoʻī e pale aku i ka hoʻopili electromagnetic. Ke piʻi nei ka ʻenehana i ka ʻoi aku ka pololei a me nā ʻōnaehana paʻakikī, ʻoi aku ka paʻakikī o nā koi no ka hoʻohālikelike electromagnetic o nā mea hana. ʻO nā paepae kikoʻī Granite, me kēia pono kūʻokoʻa, ua paʻa e hoʻomau i ka hana koʻikoʻi i ka hana kiʻekiʻe a me ka noiʻi ʻepekema ʻokiʻoki, e kōkua ana i ka ʻoihana e wāwahi mau i nā bottlenecks ʻenehana a hiki i nā kiʻekiʻe hou.
