The quantum computer, is a "supercomputer" that relies on the phenomena of quantum mechanics to perform operations on data. Object of suppositions, sometimes far-fetched, quantum mechanics gave birth to the quantum computer, a machine capable of processing data tens of millions of times faster than a conventional computer. A quantum computer doesn't use the same memory as a conventional computer. Rather than a sequence of 0 and 1, it works with qubits or quantum bits. The quantum computer is a combination of two major scientific fields: quantum mechanics and computer science. Quantum mechanics, on which this computer is based, governs the movement of bodies in the atomic, molecular and corpuscular domains, is a theory whose logic is totally contrary to intuition and it is essential to use mathematics to fully grasp it. Quantum computing is the sub-domain of computer science that deals with quantum computers using quantum mechanical phenomena, as opposed to those of electricity exclusively, for so-called "classical" computing. The quantum phenomena used are quantum entanglement and superposition. The article examines some aspects related to the development, operation, advantages and difficulties, applications and future of the quantum computer. |

Obiectul presupunerilor, uneori îndelungate, mecanica cuantică a dat naștere computerului cuantic, o mașină capabilă să proceseze date de zeci de milioane de ori mai rapid decât un computer convențional. Un computer cuantic nu folosește aceeași memorie ca un computer convențional. Mai degrabă decât o secvență de 0 și 1, funcționează cu qubiți sau biți cuantici. Calculatorul cuantic este o combinație a două domenii științifice majore: mecanica cuantică și informatică. Mecanica cuantică, pe care se bazează acest computer, guvernează mișcarea corpurilor în domeniile atomic, molecular și corpuscular, este o teorie a cărei logică este total contrară intuiției și este esențial să folosească matematica pentru a o înțelege pe deplin. Calculul cuantic este subdomeniul informaticii care se ocupă cu computerele cuantice care utilizează fenomene mecanice cuantice pentru așa-numitele calcule „clasice”. Fenomenele cuantice utilizate sunt corelarea cuantică și suprapunerea. Articolul analizează unele aspecte legate de dezvoltarea, modul de funcționare, avantajele și dificultățile, aplicațiile și viitorul calculatorului cuantic.</p></cfAbstr> <cfResPubl_Class> <cfClassId>eda2d9e9-34c5-11e1-b86c-0800200c9a66</cfClassId> <cfClassSchemeId>759af938-34ae-11e1-b86c-0800200c9a66</cfClassSchemeId> <cfStartDate>2021-04-05T24:00:00</cfStartDate> </cfResPubl_Class> <cfResPubl_Class> <cfClassId>e601872f-4b7e-4d88-929f-7df027b226c9</cfClassId> <cfClassSchemeId>40e90e2f-446d-460a-98e5-5dce57550c48</cfClassSchemeId> <cfStartDate>2021-04-05T24:00:00</cfStartDate> </cfResPubl_Class> <cfPers_ResPubl> <cfPersId>ibn-person-38516</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2021-04-05T24:00:00</cfStartDate> </cfPers_ResPubl> <cfFedId> <cfFedIdId>ibn-doi-126778</cfFedIdId> <cfFedId>10.52326/jes.utm.2021.28(1).08</cfFedId> <cfStartDate>2021-04-05T24:00:00</cfStartDate> <cfFedId_Class> <cfClassId>31d222b4-11e0-434b-b5ae-088119c51189</cfClassId> <cfClassSchemeId>bccb3266-689d-4740-a039-c96594b4d916</cfClassSchemeId> </cfFedId_Class> <cfFedId_Srv> <cfSrvId>5123451</cfSrvId> <cfClassId>eda2b2e2-34c5-11e1-b86c-0800200c9a66</cfClassId> <cfClassSchemeId>5a270628-f593-4ff4-a44a-95660c76e182</cfClassSchemeId> </cfFedId_Srv> </cfFedId> </cfResPubl> <cfPers> <cfPersId>ibn-Pers-38516</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-38516-3</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2021-04-05T24:00:00</cfStartDate> <cfFamilyNames>Băjenescu</cfFamilyNames> <cfFirstNames>Titu-Marius</cfFirstNames> </cfPersName_Pers> </cfPers> <cfSrv> <cfSrvId>5123451</cfSrvId> <cfName cfLangCode='en' cfTrans='o'>CrossRef DOI prefix service</cfName> <cfDescr cfLangCode='en' cfTrans='o'>The service of issuing DOI prefixes to publishers</cfDescr> <cfKeyw cfLangCode='en' cfTrans='o'>persistent identifier; Digital Object Identifier</cfKeyw> </cfSrv> </CERIF>
