Foreword
Sensortechnologyisattheforefrontofmoderntechnology.Manycountrieshaveregardedsensortechnology,alongwithcommunicationandcomputertechnology,asequallyimportantandreferredtothemasthethreepillarsofinformationtechnology.Quantumsensors,inparticular,representadisruptiveandrevolutionarytechnologyinthefieldofsensing.Theyhavebeenhailedasa"multiplier"forindustrialproductionanda"pathfinder"forscientificresearch.
Earlierthisyear,ourorganization,inconjunctionwithPhotonBox,releasedthe"GlobalQuantumMetrologyandSensingIndustryDevelopmentReportfor2022,"whichgainedwidespreadattentionduetothewide-rangingapplicationofquantumprecisionmeasurement.Thereportwascompiledbasedontheresearchframeworkofquantumcomputingandquantumcommunicationandiscurrentlytheindustrysfirstcomprehensiveindustrialresearchreportonquantumprecisionmeasurement.Ithasdrawnconsiderableattentionwithinthequantumsensorindustry,andasaresult,wehavedecidedtocontinueourannualupdatestothequantumprecisionmeasurementindustryreporttofurthercontributetothefield.
Thisyear,ourresearchteamhascontinuedtoconductin-depthresearchonthequantumprecisionmeasurementindustry,andwehaveachievedexcellentresults.Wewillchangeourfocusonquantumsensorsthathavealreadybeenrealized.Ourmainindustrychainanalysiswillfocusonmorematureareassuchastimemeasurement,gravitymeasurement,andmagneticfieldmeasurement.Theseareasmainlyincludeatomicclocks,coldatominterferometrygravitymeters,andopticalmagnetometers.Otherquantumsensorsthatarenotyetmatureorcurrentlyreceivelessattentionwillbecategorizedas"others,"suchasquantumopticaldevices,quantumradar,andatomicantennas.
