kamepiula laser
ʻO ka wikiwiki o ka uaki o nā kaʻina hana 1 GHz he hoʻokahi piliona hana i kēlā me kēia kekona. Nui, akā ʻo nā hiʻohiʻona maikaʻi loa i loaʻa i ka mea kūʻai maʻamau ua loaʻa i nā manawa he nui. He aha inā e wikiwiki ... hoʻokahi miliona manawa?
ʻO ia ka mea i hoʻohiki ʻia e ka ʻenehana kamepiula hou, me ka hoʻohana ʻana i nā pulses o ke kukui laser e hoʻololi i waena o nā mokuʻāina "1" a me "0." Heluhelu maʻalahi kēia quadrillion manawa i kekona.
I nā hoʻokolohua i hana ʻia ma 2018 a wehewehe ʻia i loko o ka puke moʻolelo Nature, ua puhi nā mea noiʻi i nā kukuna laser infrared pulsed ma nā ʻano honeycomb o tungsten a me selenium (1). ʻO kēia ka mea i hoʻololi ai ka chip silicon hui ma waena o ka zero a me ka mokuʻāina hoʻokahi, e like me ka mea hana kamepiula maʻamau, ʻoi aku ka miliona mau manawa ʻoi aku ka wikiwiki.
Pehea i hana ai kēia? Hōʻike ka poʻe ʻepekema i kēia kiʻi, e hōʻike ana he "ʻano ʻē" nā electrons i loko o nā honeycombs metala (ʻaʻole naʻe he nui). Ke hauʻoli, lele kēia mau ʻāpana ma waena o nā mokuʻāina quantum like ʻole, i kapa ʻia "pseudo-wili".
Hoʻohālikelike nā mea noiʻi me nā treadmills i kūkulu ʻia a puni nā molekala. Kapa lākou i kēia mau ala he "awāwa" a wehewehe i ka hana ʻana o kēia mau mokuʻāina ʻo "dolinatronica » (S).
Hoʻoulu ʻia nā electrons e nā pulses laser. Ma muli o ka polarity o nā pulse infrared, "noho" lākou i kekahi o nā "awāwa" ʻelua a puni nā ʻātoma o ka lattice metala. Manaʻo koke kēia mau mokuʻāina ʻelua i ka hoʻohana ʻana i ke ʻano ma ka lolouila kamepiula zero-one.
He wikiwiki loa ka lele uila, i nā pōʻai femtosecond. A eia ka mea huna i ka wikiwiki kupaianaha o nā ʻōnaehana alakaʻi laser.
Eia kekahi, ua hoʻopaʻapaʻa nā kānaka ʻepekema ma muli o nā hopena kino, aia kēia mau ʻōnaehana, ma ke ʻano, ma nā mokuʻāina ʻelua i ka manawa like (kūlana kiʻekiʻe), e hana ana i na manawa no. Hoʻomaopopo ka poʻe noiʻi i kēia mau mea a pau i loko wela lumiʻoiai ʻo ka hapa nui o nā kamepiula quantum e koi nei i nā ʻōnaehana hoʻomaha o nā qubits i nā mahana kokoke i ka ʻole ʻole.
"I ka wā lōʻihi, ʻike mākou i kahi hiki maoli ke hana i nā mea quantum e hana wikiwiki i nā hana ma mua o hoʻokahi oscillation o kahi nalu māmā," i ʻōlelo ai ka mea noiʻi ma kahi ʻōlelo. Rupert Huber, Polopeka no ka Physics ma ke Kulanui o Regensburg, Kelemānia.
Eia nō naʻe, ʻaʻole i hana nā ʻepekema i nā hana quantum maoli ma kēia ʻano, no laila, ʻo ka manaʻo o kahi kamepiula quantum e hana ana i ka lumi wela e noho mau wale nō. Hoʻohana like ia i ka mana helu maʻamau o kēia ʻōnaehana. ʻO ka hana o nā oscillations wale nō i hōʻike ʻia a ʻaʻohe hana helu maoli i hana ʻia.
Ua hoʻokō ʻia nā hoʻokolohua e like me nā mea i hōʻike ʻia ma luna. Ma 2017, ua paʻi ʻia kahi wehewehe o ka noiʻi ma Nature Photonics, me ke Kulanui o Michigan ma US. Ma laila, 100-femtosecond pulses o ke kukui laser i hele i loko o ke aniani semiconductor e nānā i ke kūlana o nā electrons. Ma ke ʻano maʻamau, ua like nā hanana i loko o ke ʻano o ka mea i hōʻike ʻia ma mua. Pēlā nā hopena quantum.
ʻO nā'āpana māmā a me nā perovskite
hana "kamepiula laser quantum » ʻokoʻa kona ʻano. ʻO ʻOkakopa i hala, ua hōʻike kahi hui noiʻi US-Iapana-Australian i kahi ʻōnaehana helu māmā. Ma kahi o nā qubits, hoʻohana ke ala hou i ke ʻano kino o nā kukuna laser a me nā kristal maʻamau e hoʻohuli i nā kukui i kahi ʻano kukui kūikawā i kapa ʻia ʻo "kuhi ʻia."
No ka moku'āina hui e hōʻike i ka mana helu helu quantum, pono e ana ʻia ka laser ma kekahi ʻano, a e hoʻokō ʻia kēia me ka hoʻohana ʻana i kahi pūnaewele quantum-entangled o nā aniani, beam emitters, a me nā fiber optical (2). Hōʻike ʻia kēia ala ma kahi pānaʻi liʻiliʻi, ʻaʻole ia e hāʻawi i nā wikiwiki helu kiʻekiʻe. Eia nō naʻe, ʻōlelo ka poʻe ʻepekema hiki ke hoʻonui ʻia ke kumu hoʻohālike a hiki i nā hale nui ke hoʻokō i kahi pōmaikaʻi quantum ma mua o nā kumu hoʻohālike o kēia manawa.
2. ʻO nā kukuna laser e hele ana ma kahi pūnaewele paʻakikī o nā aniani
"ʻOiai he mea kupanaha nā mea hana quantum i kēia manawa, ʻaʻole maopopo inā hiki ke hoʻonui ʻia i nā nui nui loa," wahi a Science Today. Nicolas Menicucci, he mea noiʻi komo ma ka Center for Quantum Computing and Communications Technologies (CQC2T) ma RMIT University ma Melbourne, Australia. "Hoʻomaka kā mākou ala me ka scalability koʻikoʻi i kūkulu ʻia i loko o ka chip mai ka hoʻomaka ʻana no ka mea ʻo ka mea hana, i kapa ʻia ʻo ka cluster state, ua hana ʻia me ka māmā."
Pono pū nā ʻano lasers hou no nā ʻōnaehana photonic ultrafast (e nānā pū:). ʻO nā kānaka ʻepekema mai ka Far Eastern Federal University (FEFU) - me nā hoa hana Lūkini mai ITMO University, a me nā ʻepekema mai ke Kulanui o Texas ma Dallas a me ka Australian National University - i hōʻike ʻia ma Malaki 2019 i loko o ka puke pai ACS Nano ua hoʻomohala lākou i kahi ʻano hana kūpono, wikiwiki a maʻalahi nā lasers perovskite. ʻO kā lākou ʻoi aku ma mua o nā ʻano ʻē aʻe, ʻoi aku ka paʻa o ka hana ʻana, he mea koʻikoʻi ia no nā chips optical.
"ʻO kā mākou ʻenehana paʻi laser halide e hāʻawi i kahi ala maʻalahi, kumukūʻai a hoʻomalu nui ʻia e hana nui i nā ʻano lasers perovskite. ʻO ka mea nui, ʻo ka geometry optimization i ke kaʻina paʻi laser hiki ke hana i nā microlasers perovskite paʻa paʻa no ka manawa mua (3). ʻO ia mau lasers e hoʻohiki nei no ka hoʻomohala ʻana i nā ʻano optoelectronic a me nā nanophotonic, sensors, etc., "i wehewehe ʻo Alexey Zhishchenko, kahi mea noiʻi ma ke kikowaena FEFU, i ka paʻi.
3. Nā kukuna laser Perovskite
ʻOiaʻiʻo, ʻaʻole mākou e ʻike i nā kamepiula pilikino "e holo ana i nā lasers" i kēlā me kēia manawa koke. I kēia manawa, ʻo nā hoʻokolohua i hōʻike ʻia ma luna nei he mau hōʻoia o ka manaʻo, ʻaʻole nā prototypes o nā ʻōnaehana kamepiula.
Eia naʻe, ʻo nā wikiwiki i hāʻawi ʻia e nā kukui a me nā kukuna laser he mea hoʻowalewale loa i nā mea noiʻi, a laila nā ʻenekinia, e haʻalele i kēia ala.
