Chinyorwa chine mhedzisiro yekuedza zvakabudiswa mubhuku renhau Prx. Quantum Tomography inonzi maitiro anobvumira masayendisiti kubvisa rondedzero yehuwandu hwehuwandu kubva ku data yekuedza. Zvakakodzera, tomography inofanira kupa iyo yakanyanya kutsanangurwa kutsanangurwa sekutsanangurwa nedentity matrix. Nekudaro, nekuwedzera kwehuwandu hwemakabvu muhurongwa, huwandu hwezviyero zvinodiwa zviri kukura exponentially, izvo zvinoita kuti zviite zvisingaite.
Kugadzirisa dambudziko iri muna 2017, imwe nzira yaive yakagadziriswa inonzi "mumvuri tomography". Zvinotitendera kuti ubudise zvakawanda (kunyangwe zvisiri zvese) zvimiro zvehuwandu hushoma hwezviyero, kutukwa kwekunzi "kwekutukwa kwenzira yemumvuri, semuenzaniso, mu Shanda weScot Aarotson (Scott Aaronson) Shadown Tomography of Quantum States).
Gore rapfuura, Xin-Yuan Huang (HSIN-Yuan Huang), Richard Kunyar (John Preskill (John Preskill) akaisa maitiro ezvikamu zvinodiwa uye akagadzira mimhanzi yetemo Wona (H. -Y. Huang, R. Kueng, uye J. Preskill, kufanotaura zvakawanda zvivakwa zvehuwandu hwehuwandu kubva kuzviyero zvishoma). Yaive nzira iyi yaive yakaitwa nekuedzwa neffficist kubva kuCCT MSU.
Kwayedza, quantimv-quantum-Optical system yakasarudzwa. Ccc masayendisiti akagadzira nzira yekunzwisisa iyo cube system yechiedza chechiedza chakakodzera kufanotaura nezvenyaya yezvivakwa zvinoshandiswa mimvuri yekare Nhamba yehuwandu ichishandisa nhamba diki kwazvo yezvikamu zveiyi mamiriro).
Kuongorora kwekuedza kweiyo mamiriro ezvinhu ezvemamiriro ezvinhu asina kukwana kwezviyero zvinowanikwa kubva mumumvuri wacho haatenderi uye anowana huwandu hwezviyero zvinoshandiswa kuongorora zvakanyanya kushoma pane kuverengerwa kwakakwana kwekuvakazve kwe iyo nyika. Nekudaro, iyo protocol inogona kushandiswa chaizvo kubata chaiyo yekuedza data.
"Kuratidzwa kweiyo nzira yekuedza yekubatsira yeiyo Shadhhey Danho rakakosha pakuzivikanwa kwaro nenharaunda," anodaro mumwe wevanyori vechinyorwa, musoro wehuwandu hwepakati pekisimusi yehuwandu hwehuwandu hwe Moscow University University Stanislav Huraslav.
- Pfungwa huru iri nyore uye yakajeka, hazvidi chero nzira yakaoma yedata, saka isu tinofunga nezvehunyanzvi hwekuwedzera kukosha kwekuwedzera kwekushandisa kushandiswa mumunda wekuedza mumunda wehuwandu hwehuwandu hwehuwandu hwehuwandu. Izvi zvinova zvakakosha zvakanyanya nekuuya kwehurongwa hwemhando dzedunhu hwakawanda, hwakaita semutemo, hunogara hwakaoma. "
Nekudaro, sezvo masayendisiti anoona, mumvuri tomOrshiphy tsika nenzira isingabvumirwe, sezvazvinoongorora kwete mamiriro pachayo, asi zvimwe zvezvivakwa zvaro. Panyaya yeiyo yakakwirira yedanho system, iyi nzira inogona kunge iri nzira yekusarudza yeye muedzo inofarira kufungidzira yakatarwa yakatarwa seti yemamiriro ezvinhu. Asi kana rumwe ruzivo nezve mamiriro ehurongwa runodiwa, semuenzaniso, kuti vanzwisise zvinyorwa zvekushongedza muhurongwa, dzimwe nzira dziri nani kana dzichiratidzika kunge dzichiratidzika kubva pakufunga kwehuwandu hunodiwa hwezviyero.
Yeuka kuti pakati peTemberi yeTo Quentum yeMoscow University, basa rinoitwa pakusikwa kweiyo manhamba ehuwandu hwemitengo miviri Nekuwedzera kwekuwedzera muhuwandu hwemakabvu anoshandiswa, dambudziko rekuyedza marefu marejista inonyanya kuwirirana. Pfungwa dzeMumvuri Tomography inogona kuumba hwaro hwenzira dzitsva, dzisingachinjiki dzinodhura uye kutsvaga zvikanganiso, uye tsvaga kushandiswa kushandiswa kwekushandisa kana kukudziridza zvizvarwa zvitsva zvehuwandu hwehuwandu.
