Quantum computing is one of the most important research areas for developing futuristic technologies. IBM has been at the forefront by developing superconducting quantum devices and providing cloud-based services. Initially limited to gate level access, IBM now provides cloud servers to access pulse level control of quantum devices for their algorithms. In this paper, we compare the performance of gate level and pulse level quantum encoding, control and measurement on the single qubit IBM Armonk quantum computer. Specifically, for the simulation of Rabi and Ramsey evolution dynamics-key components of many quantum metrology and clock synchronization algorithms, we show that the ability to re-calibrate pulse frequency and amplitude in realtime for pulse access allows significant improvement in the simulation of these two dynamics when compared with the gate level access.
