Izinsimbi Ze-Zurich kanye ne-QuantWare Zinikeza Ukufundwa Kwe-Qubit Ngaphandle Kwebhokisi

Zurich Izinsimbi futhi I-QuantWare, abaholi bezinhlelo zokulawula i-quantum kanye namadivayisi we-superconducting quantum, ngokulandelana, babambisene ukuthuthukisa ukufinyeleleka nokusebenza kobuchwepheshe bekhompyutha be-quantum. Bethula inoveli, isixazululo esihlanganisiwe esenza kube lula ukushuna uchungechunge lokufunda oluphelele lwe-qubit, olubalulekile ekuzuzeni ukufundwa kwe-qubit okuthembekile. Lesi sixazululo sihlanganisa i-QuantWare's Crescendo-S, isikhulisi sepharamitha wamagagasi ohambahambayo esidizayinelwe ukufundeka kalula, nesilawuli esithuthukisiwe se-Zurich Instruments kanye ne-elekthronikhi efundwayo. Lokhu kubambisana kuthembisa ukusebenza kokufunda okunomkhawulo we-quantum futhi kuhloswe ukusheshisa ukuthuthukiswa kwezinhlelo zokusebenza zekhompuyutha ezisebenzayo ngokwenza ubuchwepheshe obuyindida busebenziseka kalula futhi busebenze ngempumelelo. Ukuhlanganiswa kusekelwa futhi isilawuli sephampu yepharamitha ehlukile ye-Zurich Instruments kanye nesofthiwe ye-LabOne Q, ethuthukisa ukwethembeka kokufunda nokwenza lula ukusethwa okuphelele kwabasebenzi bekhompuyutha be-quantum.

I-Quantum Computing Inc. Ivikela Ukuthengiswa Kwe-Revolutionary Underwater LiDAR Prototype

Inkampani ye-Quantum Computing, Inc. (QCi), iphayona ku-quantum optics kanye ne-nanophononics, kumemezela ukuthengiswa kwe-prototype yayo ye-quantum ye-LiDAR e-Johns Hopkins University ngama- $200,000. I-prototype, enesixazululo esingu-3mm futhi ingasebenza kuze kufike kumamitha angama-30 ngaphansi kwamanzi, imele impumelelo ebalulekile kubuchwepheshe be-LiDAR obungaphansi kwamanzi. Lolu hlelo luhlukaniswa ngekhono lalo lokushuna kanye nesango lesikhathi ama-photon angawodwa kumasiginali yokubuyisela ye-LiDAR, okuthuthukisa ukunemba nokujula kwezifundo zemvelo ezingaphansi kwamanzi. U-Johns Hopkins uzosebenzisa i-prototype ukwenza ucwaningo nentuthuko, okungenzeka ukuthi ithuthukise ukuqonda kwethu izenzakalo zangaphansi kwamanzi. Ubuchwepheshe be-QCi, obuhlanganisa ukutholwa kwe-photon okuthuthukisiwe kanye ne-laser eluhlaza ukuze kungene amanzi anele, ihlose ukwenza lula amasu aphelele okuphathwa kwemvelo kanye nokuvikela ngokunikeza imininingwane engakaze ibonwe kanye nokunemba ekufanekisweni kwamanzi ngaphansi kwamanzi.

Isikhungo Solwazi Lwe-Quantum (CQI), Inyuvesi yaseTsinghua, Abacwaningi baseBejing Bamemezela Ukuhlolwa Okuyimpumelelo Kwe-Quantum Memory Framework

Abacwaningi at Isikhungo Solwazi Lwe-Quantum at Tsinghua University e Beijing wenze intuthuko enkulu ku-quantum computing ngokwakha nokuhlola ngempumelelo uhlaka olusha lwenkumbulo ye-quantum oluhlelekayo, olusanda kuchazwa kabanzi ekushicilelweni kwabo Ukubuyekezwa Komzimba X iphephabhuku. Le nkumbulo ye-quantum ingagcina ama-optical qubits angama-72 futhi isingathe imisebenzi yokufunda noma yokubhala eyi-1,000 elandelanayo, ekhombisa umthamo nokusebenza okudlula kakhulu amamodeli angaphambilini. Umsebenzi wabacwaningi ugqamisa amandla enkumbulo ye-quantum njengobuchwepheshe obuyisisekelo bokuphindaphinda kwe-quantum, ebalulekile ekwakheni amanethiwekhi abanzi we-quantum kanye nokwenza lula ukubala kwe-quantum yenethiwekhi. Lokhu kuphumelela kusekela ukusunduza komhlaba wonke ekufezeni amanethiwekhi we-quantum asebenzayo, ahambisana nemizamo eqhubekayo ye-inthanethi ye-quantum emadolobheni afana ne-Chicago, NYC, ne-Chattanooga, kanye nabahlinzeki bamafu abakhulu njenge-AWS. Inkumbulo ye-quantum entsha yeqembu le-Tsinghua ithembisa ukuthuthukisa ngokuphawulekayo amandla nokusebenza kahle kwamanethiwekhi e-quantum, ivule indlela yezinhlelo zokusebenza zekhompuyutha ze-quantum eziyinkimbinkimbi.

Ososayensi be-MIT bashuna isakhiwo sokubopha ngoxhaxha lwama-qubits

Abacwaningi basuka Ama-MIT's Iqembu le-Engineering Quantum Systems (EQuS) lina ithuthuke kakhulu i-quantum computing ngokwakha isu lokukhiqiza nokulawula ukubambelela phakathi kwama-superconducting qubits ngempumelelo. Le mpumelelo, eshicilelwe kuMvelo, ivumela ukukhohlisa izinhlobo zokubopha kanye nokushintsha phakathi komthetho wevolumu kanye nokubambeka komthetho wendawo, okubalulekile ekuthuthukiseni amandla ekhompuyutha ye-quantum. Ithimba lisebenzise iphrosesa ye-quantum enama-qubits angu-16 ahlelwe ngegridi enezinhlangothi ezimbili, lisebenzisa ubuchwepheshe be-microwave ukuze lilungise imvelo yokubambeka. Leli khono libonisa amandla okulingiswa kwe-quantum okuthuthukisiwe futhi liphawula igxathu eliya phambili ekuqondeni nasekusebenziseni ukubambelela kwezinhlelo zokusebenza zekhompuyutha ze-quantum ezisebenzayo. Impumelelo yokuhlolwa igqamisa amandla aqinile we-superconducting quantum processors. Ibeka isiteji sokuhlola okuzayo ekuziphatheni kwe-thermodynamic kwamasistimu e-quantum ayinkimbinkimbi, angenakufinyeleleka ezindleleni zekhompuyutha zakudala.

Abacwaningi baseCarnegie Mellon University bathuthukisa enye indlela yokufunda ejulile yokuqapha i-laser powder bed fusion

ECarnegie Mellon University's College of Engineering, abacwaningi athuthukile indlela yokufunda ejulile enoveli yokuqapha okubonakalayo kwe-in-situ kokukhiqizwa kwezithako zensimbi (AM), ikakhulukazi ngesikhathi senqubo ye-laser powder bed fusion (LPBF). Le ndlela yokusungula isebenzisa i-acoustic ekhishwa emoyeni kanye ne-thermal ukuze ithwebule futhi ihlaziye i-melt pool geometries, inikeze enye indlela engabizi kakhulu kunezinhlelo zamakhamera ezijwayelekile ezinesivinini esikhulu, ezidinga amathuluzi abizayo kanye nokuphathwa kwedatha okubanzi. Ishicilelwe ku Ijenali Yokukhiqiza Okungeziwe, indlela yeqembu cishe ingabikezela ngokushesha ukuhlukahluka kwechibi elincibilikayo futhi ithole amaphutha avamile njengokuntuleka kokuhlanganisa. Le nqubo inciphisa izindleko nobunzima bokuqapha futhi ithuthukisa amandla okukhiqiza imikhiqizo ehlala isikhathi eside ngokuhlonza nokulungisa amaphutha ngesikhathi sangempela. Ucwaningo luhlose ukwandisa ukusetshenziswa kwalo kwezinye izinto zokwakha kanye nezinqubo zokukhiqiza okungeziwe, okungenzeka kube nokuguqula ukuqapha kwe-AM ngobuchwepheshe obufinyeleleka kalula nobusebenza kahle.

Ukuboniswa kokuboshelwa kwezithombe ezintathu okumenyezelwe ku-photonic chip evela e-University of Science and Technology of China

Abacwaningi e-University of Science and Technology of China baye bathuthuke kakhulu kwi-photonic quantum computing by ukubonisa isimo seqoqo elikhulu, ikakhulukazi i-three-photon entanglement, okuyintuthuko ebalulekile ekusebenziseni i-quantum computation ezinhlelweni ze-photonic. Ishicilelwe ku Izincwadi zokubukeza ngokomzimba, ucwaningo lwabo lubhekana nenselelo yokusebenzelana okubuthakathaka kwe-photon, okuye kwaba yisithiyo esikhulu ekuzuzeni i-quantum computation ene-photons. Ithimba lenze ngempumelelo isimo se-3-GHZ esimenyezelwe ku-photonic chip lisebenzisa ichashazi lezinga eliphezulu le-InAs/GaAs le-quantum njengomthombo wesithombe esisodwa ngokusebenzisa amasu afana nokuhlanganisa nokukhipha i-percolation. Lokhu kuphumelela kungase kusheshise ukuthuthukiswa kwamakhompuyutha amelana namaphutha, amakhulu e-optical quantum computer, kuthuthukise ukusebenza kahle kanye nekhono le-photonic quantum computing futhi kusisondeze ekuboneni okuhle okungase kube khona, okuhlanganisa ukusebenza endaweni yokushisa kanye nokungahlangani kahle.

Kwezinye Izindaba: Airbus isihloko: “Ingabe i-quantum computing inika amandla i-decarbonisation yendiza?” 

Airbus ihlola ngamandla ekhompuyutha ye-quantum ukuze iguqule ubuchwepheshe be-aerospace, ikakhulukazi ezindaweni ezifana nokwenza kahle kwendiza kanye nokulayisha impahla, njengoba kushiwo enguqulweni yakamuva. iposi blog. Esikhungweni sayo sokusungula iSilicon Valley, i-Acubed, i-Airbus yenze ucwaningo ngokusebenza kahle kwe-quantum trajectory ngo-2023, ikhombisa ukuthi ama-algorithms e-quantum angahle ayenze ibe ngcono kanjani izindlela zendiza ngesikhathi sangempela ngokubala izinto eziguquguqukayo eziyinkimbinkimbi njengokuhamba komoya nesimo sezulu. Ngo-2022, i-Airbus yaphinde yasebenzisa ikhompuyutha ye-IonQ ye-quantum yecala lokusebenzisa ukulayisha impahla, ihlose ukuxazulula 'inkinga ye-knapsack' eyinkimbinkimbi yokulayisha ngempumelelo iziqukathi zempahla. Ngale kwalezi zinhlelo zokusebenza ezingokoqobo, i-Airbus iphinde ihlole i-quantum computing ku-computational fluid dynamics ukuze kuthuthukiswe ukwakheka kwendiza kanye nokusebenza kwe-aerodynamics, kwephule izingqinamba zamanje zokubala. Lolu hlelo luyingxenye yemizamo ebanzi, okuhlanganisa ukusebenzisana nabakwa-BMW ngokusebenzisa i-Quantum Mobility Quest, ukuze kuthuthukiswe ubuchwepheshe be-quantum ekuthuthukiseni izixazululo ezisimeme zezindiza kanye nokunciphisa imboni ye-carbon footprint.
