Kushandiswa kwe quantummicrowave photonics tekinoroji
Kuonekwa kwechiratidzo chisina simba
Imwe yeanonyanya kuvimbisa mashandisirwo eiyo quantum microwave photonics tekinoroji ndeyekuonekwa kweiyo isina kusimba microwave/RF masaini. Nekushandisa imwe chete yekuona photon, masisitimu aya anonyanya kunzwisiswa kupfuura nzira dzechinyakare. Semuenzaniso, vatsvakurudzi vakaratidza quantum microwave photonic system iyo inogona kuona zviratidzo zvakaderera se -112.8 dBm pasina chero magetsi amplification. Iyi yekupedzisira-yepamusoro senitivity inoita kuti ive yakanaka kune maapplication akadai seyakadzika nzvimbo kutaurirana.
Microwave photonicssignal processing
Quantum microwave photonics inoshandisawo yakakwirira-bandwidth chiratidzo chekugadzirisa mabasa akadai sechikamu chekuchinja uye kusefa. Nekushandisa dispersive optical element uye kugadzirisa wavelength yechiedza, vaongorori vakaratidza chokwadi chekuti RF chikamu chinochinja kusvika ku8 GHz RF kusefa bandwidths kusvika ku8 GHz. Zvakakosha, zvinhu izvi zvese zvinowanikwa uchishandisa 3 GHz zvemagetsi, izvo zvinoratidza kuti kuita kunodarika echinyakare bandwidth miganho.
Kwete-yenzvimbo frequency kune nguva mepu
Imwe inonakidza kugona yakaunzwa nequantum entanglement ndeye mepu yeasiri-yenzvimbo frequency kune nguva. Iyi tekinoroji inogona kuita mepu yehuwandu hweinoenderera-wave pumped single-photon sosi kune imwe nguva domain iri kure. Iyo sisitimu inoshandisa yakakomberedzwa photon pairs umo danda rimwe rinopfuura nepa spectral sefa uye rimwe richipfuura nepakati pechinhu chinoparadzira. Nekuda kweiyo frequency kutsamira kwemafotoni akapinzwa, iyo spectral yekusefa modhi inomisikidzwa isiri-yemunharaunda kune iyo nguva domain.
Mufananidzo 1 unoratidza pfungwa iyi:
Iyi nzira inogona kuwana inochinjika spectral kuyerwa pasina kushandura zvakananga kuyerwa kwechiedza sosi.
Compressed sensing
Quantummicrowave Opticaltekinoroji inopawo nzira nyowani yekumanikidzwa kunzwa kwebroadband masaini. Vachishandisa iyo randomness inherent mukuonekwa kwehuwandu, vaongorori vakaratidza quantum compressed sensing system inokwanisa kupora.10 GHz RFspectra. Iyo sisitimu inogadzirisa iyo RF chiratidzo kune iyo polarization mamiriro eiyo yakabatana photon. Imwe-photon yekuona inozopa yakasikwa isina kurongeka yekuyera matrix yekumanikidzwa kunzwa. Nenzira iyi, iyo Broadband chiratidzo inogona kudzoserwa paYarnyquist sampling rate.
Quantum kiyi yekugovera
Pamusoro pekusimudzira echinyakare microwave photonic application, quantum tekinoroji inogona zvakare kuvandudza huwandu hwekutaurirana masisitimu senge quantum kiyi yekugovera (QKD). Vatsvagiri vakaratidza subcarrier multiplex quantum kiyi yekugovera (SCM-QKD) nekuwedzeredza microwave photons subcarrier pane quantum kiyi yekugovera (QKD) system. Izvi zvinobvumira akawanda akazvimirira quantum makiyi kuti afambiswe pamusoro peimwe wavelength yechiedza, nekudaro kuwedzera spectral kunyatsoita.
Mufananidzo 2 unoratidza pfungwa uye mhedzisiro yekuyedza yeiyo mbiri-inotakura SCM-QKD system:
Kunyangwe quantum microwave photonics tekinoroji iri kuvimbisa, pachine mamwe matambudziko:
1. Yakaganhurirwa chaiyo-nguva kugona: Iyo yazvino sisitimu inoda yakawanda yekuunganidza nguva yekuvakazve chiratidzo.
2. Kuoma kutarisana nekuputika / zviratidzo zvimwechete: Nhamba yehuwandu yekuvakazve inogadzirisa kushandiswa kwayo kune zvisingadzokorori zviratidzo.
3. Shandura kuita microwave waveform chaiyo: Mamwe matanho anodiwa kushandura histogram yakagadziridzwa kuita inoshandisika waveform.
4. Mamiriro emudziyo: Kuwedzera kudzidza nezve maitiro e quantum uye microwave photonic zvishandiso mumasanganiswa masisitimu anodiwa.
5. Kubatanidzwa: Mazhinji masisitimu nhasi anoshandisa bulky discrete zvikamu.
Kugadzirisa matambudziko aya uye kufambisira mberi munda, akati wandei anovimbisa ekutsvaga nzira ari kubuda:
1. Gadzira nzira itsva dzekugadzirisa zviratidzo zvenguva chaiyo uye kuonekwa kamwe chete.
2. Ongorora maapplication matsva anoshandisa kunzwa kwakanyanya, senge liquid microsphere measurement.
3. Tevera kuzadzikiswa kwemafotoni akabatanidzwa uye ma electrons kuderedza ukuru uye kuoma.
4. Dzidza kupindirana kwakagadziridzwa kwechiedza-nyaya muintegrated quantum microwave photonic circuits.
5. Batanidza quantum microwave photon tekinoroji nemamwe ari kubuda quantum tekinoroji.
