Master-2 Thesis
Carnot Interdisciplinary Laboratory of Burgundy (ICB)
- Achieving fast and accurate quantum gates by an adapted external control field using technique of composite pulses to have robust quantum control of the qubit system with reference to superconducting circuits implementation, preventing unwanted transitions to address the quantum gate within the lowest states without addressing the higher states
- Implemented a robust quantum gate operation by making the phase also robust using optimization techniques to find the phases of the constituent composite pulses
