Tekinoroji itsva yequantum photodetector
Chidimbu chidiki chesilicon chip quantum pasi rosemudziyo wekuona foto
Munguva pfupi yapfuura, chikwata chekutsvagisa muUnited Kingdom chakaita budiriro huru mukuita kuti tekinoroji yequantum ive diki, vakabudirira kubatanidza quantum photodetector diki pasi rose musilicon chip. Basa iri, rine musoro unoti "A Bi-CMOS electronic photonic integrated circuit quantum light detector," rakaburitswa muScience Advances. Muma1960, masayendisiti nemainjiniya vakatanga kugadzira ma transistors madiki pama microchips akachipa, hunyanzvi hwakatanga nguva yeruzivo. Iye zvino, masayendisiti kekutanga vakaratidza kubatanidzwa kwema quantum photodetectors akatetepa kupfuura bvudzi remunhu pasilicon chip, zvichitiswededza padyo nenguva ye quantum tekinoroji inoshandisa chiedza. Kuti tiwane chizvarwa chinotevera che tekinoroji yeruzivo yepamusoro, kugadzirwa kukuru kwemidziyo yemagetsi ne photonic inoshanda zvakanyanya ndiyo hwaro. Kugadzira tekinoroji ye quantum munzvimbo dzekutengeserana dziripo idambudziko riripo kune tsvakiridzo yemayunivhesiti nemakambani pasi rese. Kukwanisa kugadzira hardware ye quantum inoshanda zvakanyanya pamwero mukuru kwakakosha kune quantum computing, nekuti kunyangwe kuvaka komputa ye quantum kunoda huwandu hwakawanda hwezvikamu.
Vaongorori muUnited Kingdom vakaratidza quantum photodetector ine nzvimbo yedunhu rakabatanidzwa rema microns 80 chete ne 220 microns. Saizi diki yakadaro inobvumira quantum photodetectors kuti ikurumidze zvikuru, izvo zvakakosha pakuvhura high speed.kutaurirana kwequantumuye zvichiita kuti makombiyuta e optical quantum ashande nekukurumidza. Kushandisa matekiniki ekugadzira akasimbwa uye aripo kunotengesa kunobatsira kutanga kushandiswa kune dzimwe nzvimbo dzetekinoroji dzakadai sekuona nekutaurirana. Ma detector akadaro anoshandiswa mumhando dzakasiyana-siyana dzekushandiswa mu quantum optics, anogona kushanda patembiricha yemumba, uye akakodzera kutaurirana kwe quantum, masensa anonzwa zvakanyanya akadai sema gravitational wave detectors emazuva ano, uye mukugadzirwa kwemamwe makomputa e quantum.
Kunyangwe ma detector aya achikurumidza uye ari madiki, anonyanya kunzwa. Chinhu chikuru chekuyera quantum light ndiko kunzwa kune quantum noise. Quantum mechanics inogadzira mazinga madiki, ekutanga eruzha mumasystem ese e optical. Maitiro eruzha urwu anoratidza ruzivo nezverudzi rwe quantum light inotumirwa musystem, inogona kuona kunzwa kwe optical sensor, uye inogona kushandiswa kugadzirazve quantum state nemasvomhu. Chidzidzo ichi chakaratidza kuti kuita kuti optical detector ive diki uye nekukurumidza hakuna kukanganisa kunzwa kwayo pakuyera quantum states. Mune ramangwana, vaongorori vanoronga kubatanidza mamwe mahardware e quantum technology anokanganisa ku chip scale, kuwedzera kuvandudza kushanda kwe itsva.chinoona chemaziso, uye kuiedza mumhando dzakasiyana-siyana dzemashandisirwo. Kuti detector iwanikwe zvakanyanya, timu yekutsvagisa yakaigadzira ichishandisa ma founters anowanikwa kutengeswa. Zvisinei, timu iyi inosimbisa kuti zvakakosha kuramba tichigadzirisa matambudziko ekugadzira zvinhu zvinokwanisa kukura ne quantum technology. Pasina kuratidza kugadzirwa kwe quantum hardware inokwanisika kukura zvechokwadi, kukanganisa uye mabhenefiti e quantum technology zvichanonoka uye zvichava zvishoma. Kubudirira uku kunoratidza danho rakakosha rekuwana mashandisirwo makuru etekinoroji yekwantumu, uye remangwana re quantum computing ne quantum communication rakazara nemikana isingaperi.
