Superconducting nanoelectrical circuits are promising candidates for the physical implementation of the basic building block of a quantum computer, the qubit. We investigate how optimal control theory can be applied to optimize the dynamics of Josephson qubits. For the example of the charge qubit, several numerical methods are employed to search for external control fields which, by current technology,...
External quantum control of qubits poses an inverse problem known as Hamilton identification. We present several strategies for achieving specific physical operations, such as driving a system along a specified quantum trajectory, state trapping, entanglement generation in quantum gate realizations, and state-independent quantum operations.
