Demonstration of dynamical control of three-level open systems with a superconducting qutrit

We propose a method for the dynamical control in three-level open systems and realize it in the experiment with a superconducting qutrit. Our work demonstrates that in the Markovian environment for a relatively long time (3 mu s), the systemic populations or coherence can still strictly follow the preset evolution paths. This is the first experiment for precisely controlling the Markovian dynamics of three-level open systems, providing a solid foundation for the future realization of dynamical control in multiple open systems. An instant application of the technique demonstrated in this experiment is to stabilize the energy of quantum batteries.

Automated summary

This article presents a method for dynamical control in three-level open systems and demonstrates its implementation in an experiment with a superconducting qutrit. The results show that in a Markovian environment, the populations or coherence of the system can still strictly follow the preset evolution paths for a relatively long time (3 μs). This experiment is the first to precisely control the Markovian dynamics of three-level open systems, providing a solid foundation for future dynamical control in multiple open systems. An immediate application of this technique is to stabilize the energy of quantum batteries.
