10. Ra'ayin Mai Nazarin Masana'antu

Fahimta ta Asali: Wannan takarda ba bita ce kawai ta fasaha ba; hanyar dabara ce don haɗuwar ka'idojin masana'antu guda biyu masu rushewa: Fasahar Kwantum da Ƙirƙirar Ƙari. Babban jigon shi ne cewa AM ba kayan aiki ne kawai mai dacewa ba amma shine mahimmin tushen masana'antu don shawo kan "matsalar SWAP" da ke hana firikwensin kwantum barin dakin gwaje-gwaje. Ainihin ƙimar shawara ita ce haɗin kai na tsarin da yawan aiki, ba kawai maye gurbin sashi ba.

Kwararar Ma'ana & Matsayin Dabarun: Marubutan sun yi wayo wajen tsara hujja ta fara da aikace-aikacen da ke da ƙima, na ɗan gajeren lokaci: firikwensin kwantum don kewayawa, hoton likita, da binciken albarkatu. A nan ne a halin yanzu aka tattara kuɗin kasuwanci da na gwamnati (misali, shirin Quantum Aperture na DARPA, Shirin Fasahar Kwantum na Ƙasar Burtaniya). Ta hanyar sanya AM a matsayin mabuɗin ƙanƙantar da waɗannan firikwensin don aiki da sararin samaniya, sun ba da hujja mai ƙarfi don saka hannun jari nan da nan na R&D. Kwararar ta faɗaɗa zuwa tsarin da suka fi rikitarwa (kwamfutoci, na'urori masu kwaikwayo), suna kafa rawar tushen AM a cikin dukkan tarin QT.

Ƙarfi & Kurakurai: Ƙarfin takardar shine cikakken iyakokinta, mai faɗin fannoni, yana haɗa takamaiman dabarun AM (2PP, LPBF) zuwa buƙatun ƙaramin tsarin QT na zahiri. Duk da haka, tana nuna kuskure na gama gari a cikin bita masu sa ido: ba ta nuna kalubalen kimiyyar kayan aiki da auna ma'auni ba. Cimma "matakin kwantum" na aiki—tunanin ƙananan ƙazantaccen saman nanometer don tarkon atom, matakan ƙazanta na ɗari bisa biliyan don da'irori masu gudanar da wutar lantarki, ko kusan sifili fitar da iskar gas a cikin UHV—tare da hanyoyin AM babbar cikas ce. Takardar ta ambaci ci gaban kayan amma ba ta jaddada cewa wannan ita ce hanyar da ta fi mahimmanci ba. Kayan AM na yanzu, kamar yadda aka lura a cikin bita na MRS Bulletin [3], sau da yawa ba su da tsafta da daidaiton kaddarorin da lokutan haɗin kai na kwantum ke buƙata.

Fahimta Mai Aiki: Ga masu saka hannun jari da manajoji na R&D, abin da za a ɗauka a bayyane yake: mayar da hankali kan triad na kayan-tsari-aiki.

1. Saka Hannun Jari a cikin Kamfanonin Farawa na Kayan Musamman: Goyon bayan kamfanoni masu haɓaka kayan abinci na AM na gaba (misali, ƙura na karafa mai tsafta, photopolymers masu ƙarancin fitar da iskar gas, masu gudanar da wutar lantarki masu bugawa).
2. Kuɗi na Auna Ma'auni da Ma'auni: Taimaka wa ƙaddamarwa don ƙirƙirar ka'idojin gwaji don siffanta sassan AM a cikin yanayin da ya dace da kwantum (sanyi mai tsanani, UHV, babban RF). Wannan gibi ne da ke hana amfani.
3. Ba da Fifiko ga "Gaurayawan" Masana'antu: Hanyar da ta fi dacewa na ɗan gajeren lokaci ba AM kawai ba ce, amma AM a matsayin tushe don aiki daidai. Misali, buga ɗakin sararin samaniya mai kusa da siffa tare da LPBF, sannan yi amfani da zubar da Layer Atomic (ALD) don shafa cikakken rufi na ciki mai rufi da ƙarancin fitar da iskar gas. Haɗin gwiwa tare da kamfanonin kayan aikin ALD.
4. Duba Bayan Dakunan Gwaje-gwaje na Duniya: Kasuwar farko mafi ƙarfi kuma mai kariya na iya zama sassan da suka cancanta sararin samaniya. Bukatun SWAP suna da matuƙar tsanani, girma yana da ƙasa, kuma keɓancewa yana da girma—cikakkiyar dacewa ga ƙimar shawarar AM. Yi hulɗa da hukumomin sararin samaniya da sabbin kamfanonin Sararin Samaniya yanzu.

A ƙarshe, wannan bita ya gano daidai canji mai girman gaske. Wadanda suka yi nasara a mataki na gaba na kasuwancin fasahar kwantum ba kawai waɗanda ke da mafi kyawun qubits ba ne, amma waɗanda suka ƙware fasaha da kimiyyar gina akwatin da ke ɗauke da su.
