Quantum dot-based spin qubits are resilient towards charge noise and affected by magnetic only. However, environmental interaction leads to decoherence in these qubit systems. The external control parameters directly related the magnitude of decoherence. This turn limits range values those for which operations can be done with high fidelity. In this work, using a model quantum dot system, we investigate impact varying ac fields on suppression We report an increment usable static field value our technique.
