Effects of Dynamical Decoupling and Pulse-level Optimizations on IBM Quantum Computers

Understand

Currently available quantum computers are prone to errors.

• Circuit optimization and error mitigation methods are needed to design quantum circuits to achieve better fidelity when executed on NISQ hardware.
• Dynamical decoupling (DD) is generally used to suppress the decoherence error and different DD strategies have been proposed.
• Moreover, the circuit fidelity can be improved by pulse-level optimization, such as creating hardware-native pulse-efficient gates.
