Photonic quantum xam yog nce mus sai heev -tab sis scaling hardware platforms yuav tsum tau ntau tshaj qubit innovation. Fiber-rau-chip connectivity, tshwj xeeb tshaj yog, tau tshwm sim raws li kev txwv engineering.
Photonic quantum computers cia siab rau multichannel fiber ntau arrays rau ob peb lub teeb rau hauv photonic integrated circuits (PICs). Txawm nanometer-scale misalignment tuaj yeem qhia qhov poob ntawm photon, degrade entanglement fidelity, thiab cuam tshuam tag nrho cov system kev ua tau zoo. Thaum cov pa fiber ntau arrays tsim rau datacom thiab telecom daim ntawv thov muaj kev nkag siab, lawv tsis tau tsim los ua kom tau raws li ultralow -cov kev xav tau ntawm quantum architectures. Raws li kev lag luam hloov pauv los ntawm kev tshawb fawb prototypes mus rau kev lag luam thaum ntxov, ntim precision yuav tsum hloov zuj zus los ntawm kev sim ntsuas mus rau kev muaj peev xwm ua lag luam.
Qhov kom zoo dua ntawm qhov kev sib tw ua kom nquag plias xa mus zoo tshaj quantum systems. Txhua daim ntawv thov photonic ua haujlwm nrog cov nyiaj siv kho qhov muag tsis zoo-txawm yog rau kev sib txuas lus hauv qhov chaw, kev paub txog kev tiv thaiv, datacom, lossis telecom infrastructure- tau txais txiaj ntsig ncaj qha los ntawm kev poob qis qis thiab nruj dua channel- mus rau -channel uniformity. Rau analog optical sensing daim ntawv thov, txo coupling poob ua rau kom paub txog cov teeb liab tsis muaj zog thiab siv tau ntau dua ntawm tag nrho cov laser bandwidth ntawm, piv txwv li, lub teeb superluminescent-emitting diode (SLED; depicted nyob rau hauv daim duab hauv qab no ntawm sab xis thiab sab laug, feem). Kev poob qis kuj txhais tau hais tias lub zog tsav laser tsawg dua yuav tsum tau ua kom tau raws li cov peev txheej kho qhov muag: Lasers khiav txias dua, tsim kom muaj cua sov tsawg dua, thiab kav ntev dua. Qhov tshwm sim yog ib qho me me thermal hneev taw, txo cov cua txias saum taub hau, thiab txhim kho cov khoom lag luam thoob plaws lub rooj tsavxwm.
Tsiv dhau passive kev sib raug zoo
MicroAlign tau tsim lub micromanipulation platform los ua kom cov fibers ib leeg nrog nanometer -theem precision. Ib txwm fiber ntau arrays cia siab rau passive tso rau hauv precision V-grooves, qhov twg mechanical tolerances accumulates nyob rau hauv raws. Kev sib raug zoo, los ntawm qhov sib txawv, dynamically kho fiber ntau txoj hauj lwm thaum lub sij hawm sib dhos, kho lub suab sib txawv ua ntej fixation mus tas li. Txoj hauv kev no ua rau muaj ntau cov kab sib txuas ua kom zoo tshaj plaws rau qhov poob qis tsawg.
Raws li kev ua tau zoo lub hom phiaj nruj, kho qhov muag -coupling poob qis dua 0.5 dB tau nce siab hauv quantum thiab lwm yam siab - kawg photonic daim ntawv thov. Kev tuav cov qib poob tsis tu ncua thoob plaws cov ntim ntau lawm yuav tsum tsis yog tsuas yog precision, tab sis kuj tseem tswj cov txheej txheem rov ua dua.
Scaling ntau lawm rau cov kev xav tau tshiab
Txhawm rau txhawb kev lag luam, MicroAlign tau txais € 2.5M ($ 2.8M) EIC Accelerator Grant, uas suav nrog cov khoom sib npaug, txhawm rau ua kom lub zog ntawm peb cov fiber ntau -array manufacturing. Cov nyiaj pab txhawb nqa kev tsim cov khoom lag luam tawm thaum tswj xyuas qhov zoo ib yam, siab - cov zis zoo. Qhov kev hloov pauv no tseem ceeb heev vim tias quantum computing tuam txhab pib npaj loj dua - teev kev xa tawm. Fiber arrays tsis yog marginal subsystems hauv photonic quantum computers. Ib qho loj - nplai qhov system tuaj yeem xav tau ntau txhiab arrays. Raws li kev saws me nyuam nrawm, ib qho kev txhim khu kev qha thiab cov khoom lag luam tuaj yeem hloov tau yog qhov tseem ceeb tshaj plaws.
Ntau qhov ntom ntom ntom ntom ntom ntom ntom
Tshaj li qhov ntsuas qhov ntsuas, peb tseem hais txog qhov ceev. Thaum xyoo 2026, MicroAlign npaj yuav ua kom paub cov tiam tshiab ntawm ultrahigh - qhov tseeb fiber ntau arrays nrog channel pitches mus rau 127 µm. Kev txo qis ua rau muaj kev ntim khoom ntim ntau dua thiab txhawb nqa I / O ceev dua ntawm cov chips sib xyaw. Raws li photonic circuits suav nrog nce channel suav, ntom fiber ntau arrays dhau los ua qhov tseem ceeb los tswj cov hneev taw thiab kev ua haujlwm nyuaj.
Active alignment offers advantages in such dense configurations, where small positional errors can significantly affect aggregate optical loss across multiple channels.
Tshaj li quantum applications
Txawm hais tias quantum suav yog tus tsav tsheb tseem ceeb, qhov kev xav tau ntawm ultralow - kev sib txuas tsis tau txuas mus rau ntau lwm qhov kev tshaj lij photonic domains - thiab lub sijhawm ua lag luam hauv cov khw no yuav ua pov thawj tseem ceeb.
Hauv kev hloov kho qhov muag thiab kev ua haujlwm, microelectromechanical systems (MEMS) keyboards thiab wavelength -cov keyboards xaiv yog cov khoom tseem ceeb ntawm cov network reconfigurable rau datacenters thiab telecom backbones. Cov khoom siv no muaj kev nkag siab zoo rau qhov poob: Txhua qhov ntxiv 0.1 dB ntawm kev sib txuas tsis ua haujlwm ntawm fiber ntau - mus rau -chip interface ncaj qha erodes system margin thiab tej zaum yuav yuam kom siv cov nqi kho qhov muag ntau dua. Active-cov arrays uas muaj peev xwm ua tsis tu ncua los tsoo sub-0.5 dB poob lub hom phiaj ua rau cov neeg tsim qauv ua kom lub zog xav tau, txo qis kev siv hluav taws xob, thiab txuas mus txog yam tsis muaj kev cuam tshuam ntxiv.
Kev tiv thaiv thiab qhov chaw photonics nthuav tawm cov ntaub ntawv sib npaug. Dawb -chaw kho qhov muag qhov chaw sib txuas lus, LiDAR sensors, thiab satellite payloads txhua tus xav tau qhov ua tau zoo tshaj plaws ntawm kev sib txuas ua haujlwm kom ntseeg tau raws li qhov txwv loj, qhov hnyav, thiab lub zog (SWaP) pob nyiaj siv. Rau cov cheeb tsam no, ib feem ntawm cov decibel khaws cia ntawm fiber ntau -chip interface tuaj yeem txhais ncaj qha rau hauv qhov me me, sib dua, ntev dua - kab ke. Kev ua tau zoo sib xws thoob plaws txhua txoj kev-ib qho cim ntawm kev ua haujlwm- ua raws cov arrays- yog qhov tseem ceeb tshwj xeeb tshaj yog rau ntau cov channel sensor arrays nyob rau hauv uas channel -rau-channel variation tuaj yeem degrade ntsuas qhov tseeb.
Los ntawm 2029, MicroAlign lub hom phiaj los txhawb nqa ib feem tseem ceeb ntawm photonic quantum xam systems thoob ntiaj teb nrog nws cov ultrahigh - fiber ntau arrays. Peb lub hom phiaj tseem ceeb yog ceev ceev- loj hlob tsis yog- quantum ntu, suav nrog kev hloov kho qhov muag, kev sib txuas lus sib txuas, kev hnov lus, thiab tiv thaiv photonics- qhov twg tib lub peev xwm tsim tau zoo nyob zoo - tsim thiab ceev cov neeg siv khoom xav tau.
Precision ntim raws li kev sib tw sib txawv
Kev lag luam ntawm kev ua haujlwm sib raug zoo qhia txog kev hloov pauv dav dav rau kev tsim khoom photonics. Fiber arrays tau hloov zuj zus los ntawm cov khoom lag luam hauv xov tooj mus rau qhov tseeb -engineered subsystems hauv nruab nrab rau kev ua haujlwm ntawm lub cev- hla quantum suav, kev paub siab, kev sib txuas lus kho qhov muag, thiab kev tiv thaiv photonics.
Kev tawm quantum thiab siab -kawg photonics kev lag luam yog rov txhais cov kev cia siab: Nanometer- nplai qhov tseeb, sub-0.5 dB txuas poob, siab channel ceev, thiab scalable automation. Lub rooj sib tham tag nrho plaub ib txhij yuav tsum rov xav txog cov txheej txheem sib dhos.
Raws li photonic quantum xam txav mus rau kev xa mus rau kev lag luam, qhov scalability ntawm ntim technologies yuav ua pov thawj tseem ceeb li kev nce qib hauv qubit architectures. Thiab rau ntau lub siab -kev ua lag luam photonic uas tsis koom nrog ib qho qubit, tib zaj lus qhia siv. Hauv kev lag luam uas txhua feem ntawm ib qho decibel tseem ceeb, kev ntim khoom tsis yog qhov nthuav dav ntxiv lawm - nws yog ib qho txiaj ntsig zoo.
