Nyob rau hauv tej teb xws li semiconductor manufacturing thiab quantum precision ntsuas, uas yog rhiab heev rau electromagnetic ib puag ncig, txawm lub slightest electromagnetic cuam tshuam nyob rau hauv cov cuab yeej yuav ua rau precision deviations, cuam tshuam rau qhov kawg khoom zoo thiab kev sim. Raws li cov khoom tseem ceeb txhawb nqa cov cuab yeej precision, cov yam ntxwv sib nqus ntawm cov granite precision platforms tau dhau los ua qhov tseem ceeb hauv kev ua kom ruaj khov ntawm cov khoom siv. Kev tshawb nrhiav qhov tob ntawm qhov sib nqus susceptibility kev ua tau zoo ntawm granite precision platforms yog qhov tsim nyog rau kev nkag siab txog lawv cov nqi hloov tsis tau hauv high-end manufacturing thiab scientific scenarios. Granite feem ntau yog tsim los ntawm cov zaub mov xws li quartz, feldspar thiab mica. Cov qauv hluav taws xob ntawm cov pob zeb hauv cov pob zeb no txiav txim siab cov yam ntxwv sib nqus susceptibility ntawm granite. Los ntawm kev tsom xam, nyob rau hauv cov zaub mov xws li quartz (SiO_2) thiab feldspar (xws li potassium feldspar (KAlSi_3O_8)), electrons feem ntau muaj nyob hauv khub hauv covalent lossis ionic bonds. Raws li Pauli tshem tawm txoj cai hauv quantum mechanics, cov kev taw qhia tig ntawm cov khoom siv hluav taws xob sib txawv, thiab lawv lub sijhawm sib nqus tshem tawm ib leeg, ua rau tag nrho cov lus teb ntawm cov ntxhia rau sab nraud magnetic teb tsis muaj zog heev. Yog li ntawd, granite yog ib yam khoom siv diamagnetic uas tsis tshua muaj kev sib nqus, feem ntau nyob ib ncig ntawm qhov kev txiav txim ntawm \(-10^{-5}\), uas yuav luag tsis quav ntsej. Piv nrog rau cov khoom siv hlau, qhov sib nqus susceptibility kom zoo dua ntawm granite yog qhov tseem ceeb heev. Feem ntau cov khoom siv hlau xws li hlau yog ferromagnetic los yog paramagnetic cov khoom, nrog ntau cov khoom siv hluav taws xob tsis sib xws hauv. Lub sijhawm sib nqus sib nqus ntawm cov electrons tuaj yeem ceev ceev Orient thiab ua raws li qhov kev txiav txim ntawm ib qho chaw sib nqus sab nraud, ua rau muaj kev cuam tshuam ntawm cov khoom siv hlau zoo li qhov kev txiav txim ntawm \(10^2-10^6\). Thaum muaj cov teeb liab electromagnetic los ntawm sab nraud, cov ntaub ntawv hlau yuav sib zog ua ke nrog cov khoom sib nqus, tsim cov hluav taws xob electromagnetic eddy tam sim no thiab hysteresis poob, uas cuam tshuam nrog kev ua haujlwm ntawm cov khoom siv hluav taws xob hauv ib txwm muaj. Granite precision platforms, nrog rau lawv tsis tshua muaj magnetic susceptibility, tsis tshua muaj kev cuam tshuam nrog sab nraud magnetic teb, zoo zam tiam ntawm electromagnetic cuam tshuam thiab tsim ib tug ruaj khov kev khiav hauj lwm ib puag ncig rau precision khoom. Hauv kev siv tswv yim, qhov tsis tshua muaj kev sib nqus tsis zoo ntawm granite precision platforms plays lub luag haujlwm tseem ceeb. Nyob rau hauv quantum computer systems, superconducting qubits yog rhiab heev rau lub suab nrov electromagnetic. Txawm tias qhov sib nqus ntawm qhov sib nqus ntawm 1nT (nanotesla) qib tuaj yeem ua rau poob ntawm qubits, ua rau kev ua yuam kev. Tom qab ib pab neeg tshawb fawb tau hloov qhov kev sim platform nrog cov khoom siv granite, cov suab nrov tom qab magnetic teb nyob ib ncig ntawm cov cuab yeej poob qis los ntawm 5nT mus rau qis dua 0.1nT. Lub sijhawm sib koom ua ke ntawm qubits tau txuas ntxiv los ntawm peb zaug, thiab kev ua haujlwm yuam kev raug txo los ntawm 80%, ua kom muaj kev ruaj ntseg thiab qhov tseeb ntawm quantum xam. Nyob rau hauv lub tshav pob ntawm semiconductor lithography cov cuab yeej, cov huab ultraviolet lub teeb qhov chaw thiab precision sensors thaum lub sij hawm lithography txheej txheem yuav tsum nruj me ntsis rau lub electromagnetic ib puag ncig. Tom qab siv lub granite precision platform, cov cuab yeej siv tau zoo tiv thaiv kev cuam tshuam sab nraud ntawm electromagnetic cuam tshuam, thiab qhov chaw raug tau raug txhim kho los ntawm ± 10nm rau ± 3nm, muab cov khoom lav rau kev ruaj khov ntawm cov txheej txheem siab heev ntawm 7nm thiab hauv qab no. Tsis tas li ntawd, nyob rau hauv high-precision electron microscopes, nuclear magnetic resonance imaging cov cuab yeej thiab lwm yam cuab yeej rhiab rau electromagnetic ib puag ncig, granite precision platforms kuj xyuas kom meej tias cov cuab yeej ua tau zoo tshaj plaws vim lawv cov yam ntxwv tsis tshua muaj magnetic susceptibility. Qhov zero magnetic susceptibility ntawm granite precision platforms ua rau lawv ib tug zoo tagnrho xaiv rau precision khoom los tiv thaiv electromagnetic cuam tshuam. Raws li thev naus laus zis tau nce mus rau qhov siab dua thiab cov txheej txheem nyuaj dua, cov kev xav tau rau cov khoom siv hluav taws xob sib xyaw ua ke tau dhau los ua nruj. Granite precision platforms, nrog rau qhov tshwj xeeb kom zoo dua no, tau ua haujlwm txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv kev tsim khoom siab thiab kev tshawb fawb txog kev tshawb fawb, pab kev lag luam tas li cuam tshuam los ntawm cov kev tsis sib haum xeeb thiab mus txog qhov siab tshiab.
