This paper presents a method for dynamically suppressing decoherence in two-level quantum systems using a sequence of radiofrequency pulses, termed "quantum bang-bang" control. The technique involves repeatedly flipping the state of the system to average out the effects of environmental interactions. The study shows that continuous flipping can completely eliminate decoherence, while intervals between pulses comparable to the environment's correlation time significantly reduce it. The approach complements existing quantum error-correction techniques by actively manipulating the quantum state rather than relying solely on error-avoiding codes or feedback mechanisms. The model is analyzed for a two-state system (qubit) coupled to a thermal bath of harmonic oscillators, where decoherence is suppressed through repeated effective time-reversal operations. The results are compared to quantum error-correction methods and show that the effectiveness of the technique depends on the environment's correlation time and temperature. The paper also discusses the physical interpretation of the results, relating them to known phenomena in nuclear magnetic resonance and the quantum Zeno effect. The analysis includes examples of decoherence dynamics for different environmental configurations, demonstrating that the method can significantly reduce decoherence in both classical and quantum environments. The study concludes that the technique offers a promising strategy for preserving quantum coherence in quantum information processing.This paper presents a method for dynamically suppressing decoherence in two-level quantum systems using a sequence of radiofrequency pulses, termed "quantum bang-bang" control.
