Controlling single qubit gate fidelity in double quantum dots

Quantum computation offers ways of solving problems which are unreachable for classical computers [1]. Double quantum dots are of great interest as candidates for implementing solid state quantum bits (qubits) because of the long electron coherence times. The use of geometrically isolated structures (with the detectors coupled capacitively) improves the electrical isolation of the dots, however, it makes the detection more challenging [2].
