Description
Quantum clocks, such as atomic clocks, are known to have advantages over classical ones. Autonomous quantum clocks are a relatively new addition to this realm. What makes them particularly interesting is the little external control they need. My research is focused on a minimal thermal clock model previously proposed. This consists of two qubits operating between macroscopic heat baths, extracting work from the heat flow and exerting it onto an external system, which works as a clock. I show that the precision of this particular model is classical and reproducible by stochastic models. I will also present results showing that the ladder system used as the clock evolves with non-Markovian dynamics. Finally, I will include a study of the clock in the virtual qubit framework.
