Xov tooj cua zaus (RF) cables thiab interconnect Cheebtsam ua si ib qho tseem ceeb, txawm tias tsis pom, lub luag hauj lwm nyob rau hauv quantum xam thiab kev sib txuas lus. Vim hais tias lub xeev ntawm qubits yog qhov tsis yooj yim heev, txawm tias qhov cuam tshuam sab nraud me ntsis tuaj yeem ua rau lawv poob lawv cov cuab yeej superposition (piv txwv li, quantum decoherence). Yog li ntawd, lub luag haujlwm tseem ceeb ntawm RF cables yog muab qhov tseeb, ruaj khov, thiab ultra- qis- suab nrov microwave tsav teeb liab rau qubits.
Tshwj xeeb, daim ntawv thov ntawm RF cables nyob rau hauv quantum teb ntsib cov kev xav tau siab heev, ua rau muaj ntau yam kev txiav - ntug kev daws teeb meem:
I. Core Application Challenges thiab Technical Requirements
Txhawm rau tswj hwm kev tswj hwm ntawm qubits hauv qhov tsis tshua muaj siab - qhov kub thiab txias ib puag ncig, quantum- tshwj xeeb RF interconnect Cheebtsam yuav tsum ua raws li cov qauv nruj hauv qab no:
Tsis tshua muaj suab nrov thiab tsis tshua muaj suab nrov: Txo cov teeb liab attenuation thiab theem suab nrov, tiv thaiv RF suab nrov qhia los ntawm ib puag ncig thermal, sib nqus, los yog cov khoom siv los ntawm kev puas tsuaj rau cov ntaub ntawv khaws cia hauv qubits.
Kev ruaj ntseg ntawm qhov kub thiab txias: Quantum computers feem ntau ua haujlwm nyob rau hauv ib puag ncig zero kiag li (qis dua 4K lossis txawm tias 10mK), thiab cov cables yuav tsum muaj kev ruaj ntseg ntawm lawv cov yam ntxwv hluav taws xob thoob plaws qhov kub ntawm qhov kub ntawm chav tsev mus rau qhov kub thiab txias.
Magnetic Interference Resistant thiab Non-Magnetic Design: Txhawm rau tiv thaiv electromagnetic cuam tshuam los ntawm kev ua yuam kev, cov khoom sib txuas thiab cov kab hluav taws xob hauv cov chaw teeb liab tseem ceeb yuav tsum siv cov khoom tsis yog- cov khoom sib nqus kom tsis txhob muaj hluav taws xob cuam tshuam.
Siab -Frequency thiab High-Density Cabling: Raws li qhov system complexity nce, kev txhawb nqa rau siab - zaus ntawm ob peb GHz mus rau kaum ntawm GHz yog xav tau, thaum cov khoom sib txuas yuav tsum muaj daim ntawv cog lus kom hloov mus rau qhov chaw - txwv ib puag ncig.
II. Mainstream Application Solutions thiab Product Forms: Txhawm rau daws cov teeb meem no, kev lag luam tau pib ntau lub RF kev daws teeb meem tshwj xeeb tsim rau quantum daim ntawv thov:
1. Cryogenic Coaxial Cables thiab Cov Txuas Tshwj Xeeb:
Cryogenic Superconducting RF Cables: Cov tuam txhab hauv tsev xws li Fujitec tau ua tiav kev tsim cov khoom siv hluav taws xob RF thiab cov khoom siv microwave ntsig txog, tshwj xeeb tsim los rau cov teeb liab ruaj khov thiab kev tswj hwm hauv qhov tsis tshua muaj siab - qhov kub thiab txias. Cov khoom me me -batch tam sim no tau muab rau cov koom haum tshawb fawb hauv tsev.
Niobium-Titanium Alloy/Copper-Nickel Cables: Qee lub tuam txhab tshwj xeeb tau tsim nws tus kheej tsim superconducting niobium-titanium alloy cables uas tsis tshua muaj thermal conductivity (txog 10⁻⁸ W / mK) thiab qis thermal conductivity tooj liab- ua kom tau raws li cov khoom siv hluav taws xob thermal xam . 1. Miniaturized Non-Magnetic Connectors: Xws li SMP / SMPM series thawb- hauv cov khoom sib txuas, cov no tsis yog tsuas yog compact thiab haum rau qhov muag tsis pom kev, tab sis kuj muaj cov tsis muaj - sib nqus cov kev daws teeb meem raws li tshwj xeeb uas tsis yog- ferrous hlau, zoo tiv thaiv magnetic teb cuam tshuam.
2. RFoF (Xov tooj cua Frequency Optical Fiber Transmission) Technology: Hauv kev faib quantum tes hauj lwm thiab ntev -kev soj ntsuam quantum kev sib txuas lus, ib txwm coaxial cables muaj kev cuam tshuam loj ntawm cov zaus siab. RFOF cov kev daws teeb meem los ntawm cov tuam txhab xws li OpticalZonu tau txais los ntawm cov koom haum xws li Duke Quantum Center. Lub tshuab no hloov cov xov tooj cua zaus hloov pauv mus rau cov teeb liab kho qhov muag rau kev sib kis hauv cov fibers kho qhov muag, txo cov teeb liab attenuation los ntawm 100 npaug piv rau cov kab hluav taws xob ib txwm siv, nrog rau latency mus rau qib nanosecond, zoo heev txhim kho kev ncaj ncees ntawm quantum entanglement distribution thiab siab -precision network testing.
3. Customized Flexible Cable Assemblies: Cov tuam txhab thoob ntiaj teb zoo li Radiall siv cov thev naus laus zis xws li 3D dabtsi yog khoov tshuab los kho ib nrab- nruj lossis siab- zaus SHF cable sib dhos rau quantum computers. Cov rooj sib txoos no hais txog kev ua kom nyias nyias, yooj yim, thiab rwb thaiv tsev, ua haujlwm seamless / solderless txheej txheem los muab kev ntseeg siab dua, yog li ua kom muaj kev sib luag hauv cov txheej txheem quantum complex.
