Abstrakti

Esittelemme uuden joukon kvanttikanavia: resonanssit monitasoiset amplitudivaimennuskanavat (ReMAD). He voivat muun muassa kuvata energian haihtumista monitasoisissa atomijärjestelmissä, jotka aiheutuvat vuorovaikutuksesta nollalämpötilaisen bosonisen ympäristön kanssa. Poiketen jo tunnetusta monitasoisten amplitudivaimennuskanavien (MAD) luokasta, tämä uusi karttaluokka sallii ympäristön, joka ei pysty erottelemaan siirtymiä identtisillä energia-aukoilla. Kun olemme karakterisoineet niiden koostumussääntöjen algebran, analysoimalla qutrit-tapausta, osoitamme, että tämä uusi kanavasarja voi osoittaa hajoavuutta ja hajoamattomuutta sallitun parametriavaruuden laajoilla alueilla. Siellä laskemme niiden kvanttikapasiteetin ja yksityisen klassisen kapasiteetin. Osoitamme, että nämä kapasiteetit voidaan laskea tarkasti myös parametriavaruuden alueilla, joissa kanavat eivät ole hajoavia tai antihajoavia.
