• Abstract: We investigate the quantum synchronization dynamics of a moving qubit within a dissipative cavity environment, leveraging the Husimi $Q$-function to analyze the phase space evolution. The study explores a range of coupling strengths between the qubit and the cavity field, focusing on the interplay between qubit velocity and system detuning. In the weak coupling regime ($\lambda = 5\gamma$), the system rapidly decoheres, exhibiting minimal synchronization. Conversely, in the strong coupling regime ($\lambda = 0.01\gamma$), we observe more intricate dynamics, including phase locking and oscillatory behavior, indicating a better degree of synchronization. Our findings reveal that the qubit's velocity and detuning influence synchronization, offering potential pathways to enhance coherence in quantum systems. These insights have significant implications for quantum computing and quantum communication, where controlling synchronization can improve the stability and security of quantum states. Moreover, the ability to manipulate synchronization through environmental parameters suggests new applications in quantum metrology and sensing, where precise control of quantum states is essential.

  Quantum reservoirs have great potential as they utilize the complex real-time dissipative dynamics of quantum systems for information processing and target time-series generation without precise control or fine-tuning of the Hamiltonian parameters. We propose the disordered quantum homogenizer as an alternative platform, and prove it satisfies the necessary and sufficient conditions - stability and contractivity - of the reservoir dynamics. The results indicate that the quantum homogenization protocol, physically implementable as either nuclear magnetic resonance ensemble or a photonic system, can potentially function as a reservoir computer.
