abstract = {This paper gives an introduction on the basic concepts of quantum heat engine and quantum thermodynamics while exploring relevant properties of the quantum heat engine system based on coupled harmonic oscillators. The authors drew references from classical thermodynamics and introduces Bogoliubov transformation so as to diagonalize the potential term in coupled quantum harmonic oscillators. The authors also based the quantum heat engine system on said oscillators and gives a detailed demonstration of acquiring the efficiency of Otto cycle utilized by this system, arriving at the conclusion that there is a unifying and cohesive factor that interconnects certain corresponding values between classical and quantum heat engines.}
