Analyzing Strategies for Dynamical Decoupling Insertion on IBM Quantum Computer

Understand

Near-term quantum devices are subject to errors and decoherence error is one of the non-negligible sources.

• Dynamical decoupling (DD) is a well-known technique to protect idle qubits from decoherence error.
• However, the optimal approach to inserting DD sequences still remains unclear.
• In this paper, we identify different conditions that lead to idle qubits and evaluate strategies for DD insertion under these specific conditions.
