Ke alakaʻi nei ʻo Canada i ke ala i ka quantum e hiki mai ana

ʻO ka hui ʻo D-Wave ʻo Kanada kahi ʻanuʻu kokoke i ka hōʻoia ʻana i ka pono o kā lākou kamepiula quantum D-Wave ʻElua. Ua paʻi hou ʻia nā hopena o kahi hoʻokolohua e hōʻike ana i nā hōʻailona o ka hana quantum i loko o ke kamepiula ma Physical Review X, kahi puke pai i nānā ʻia e nā hoa.

Akā he aha ke kamepiula quantum?

Hoʻolohe ka computer quantum i nā kānāwai o ka quantum physics, ʻo ia hoʻi, physics ma kahi liʻiliʻi loa. ʻOkoʻa loa ke ʻano o nā ʻāpana liʻiliʻi ma mua o nā mea o kēlā me kēia lā a mākou e ʻike ai. Hāʻawi kēia iā lākou i nā mea maikaʻi ma mua o nā kamepiula maʻamau, e mālama ana i nā kānāwai o ka physics kahiko.

No ka laʻana, hoʻoponopono kāu kamepiula i ka ʻike ma ke ʻano he mau bits: nā zeroes a i ʻole kekahi. Hoʻohana nā computer quantum i nā qubits, mahalo i kahi hanana quantum i kapa ʻia ʻo "superposition," hiki ke lilo i zeroes, hoʻokahi, a i ʻole nā ​​​​mea ʻelua i ka manawa like. No ka mea hiki i ke kamepiula ke hana i nā koho āpau i ka manawa hoʻokahi, ʻoi aku ka wikiwiki ma mua o kāu kamepiula.

ʻIke ʻia nā pōmaikaʻi o kēia wikiwiki i ka wā e hoʻonā ai i nā pilikia makemakika paʻakikī kahi i nui loa ka ʻikepili e kānana me nā ʻōnaehana maʻamau.

Mea Hoohewa Kuantum

Ua kūʻai aku ka hui o British Columbia i kāna mau kamepiula iā Lockheed Martin, Google, a me NASA mai ka makahiki 2011. ʻAʻole kēia manaʻo nui i hoʻōki i ka poʻe kānalua mai ka hoʻopiʻi ʻana i nā ʻōlelo a ka hui. ʻO Scott Aaronson, he polopeka ma ka Massachusetts Institute of Technology, ʻo ia kekahi o nā leo leo nui loa o kēia.

Ma kāna blog, ʻōlelo ʻo Aaronson ʻaʻole i kākoʻo ʻia nā ʻōlelo a D-Wave e nā hōʻike i loaʻa i kēia manawa. ʻOiai ua ʻae ʻo ia e hoʻohana ana ke kamepiula i nā kaʻina quantum, hōʻike ʻo ia ua ʻoi aku kekahi o nā kamepiula maʻamau i ka D-Wave Two. Ua ʻae ʻo ia ua holomua ʻo D-Wave, akā ʻōlelo ʻo kā lākou "hoʻopiʻi ... ʻoi aku ka ikaika ma mua o kēlā."

Ka Hoʻoilina Quantum o Kanada

ʻAʻole nā ​​kamepiula a D-Wave wale nō ka holomua o ka quantum physics e hoʻokomo i kahi hōʻailona Kanada.

I ka makahiki 2013, ua hoʻomau ʻia nā qubits i hoʻopaʻa ʻia ma ka lumi wela no kahi kokoke i 100 mau manawa lōʻihi ma mua o ka wā ma mua. Ua alakaʻi ʻia ka hui honua i loaʻa i ka hopena e Mike Thewalt o ke Kulanui ʻo Simon Fraser ma British Columbia.

Ma Waterloo, Ont., Raymond Laflamme, ka luna hoʻokele o The Institute for Quantum Computing (IQC), ua kūʻai kūʻai aku i kahi mea ʻike photon e hoʻohana ana i ka ʻenehana quantum. ʻO kāna pahuhopu hou aʻe no ke kikowaena, ʻo ia ke kūkulu ʻana i ka lolouila quantum maʻamau. Akā, he aha ka mea hiki ke hana i kēlā mea hana?
