In this thesis, we suggest alternative quantum Otto engines, using heat bath algorithmic cooling with partner pairing algorithm instead of isochoric cooling and quantum SWAP operations instead of quantum adiabatic processes. Liquid state nuclear magnetic resonance systems in a single entropy sink are threated as working fluids. The extractable work and thermal efficiency are analyzed in detail for four-stroke and two-stroke type of alternative quantum Otto engines. The role of the heat bath algorithmic cooling in these cycles is to use a single entropy sink instead of two so that a single incoherent energy resource can be harvested and processed using algorithmic quantum heat engine. Our results indicate a path to programmable quantum heat engines as analogues of quantum computers beyond traditional heat engine cycles. We find that for our NMR system example, implementation of quantum algorithmic heat engine stages yields more power due to increased cycle speeds.
