Robust Charge-based Qubit EncodingDOI: 10.1103/PhysRevB.72.075348 Abstract: We propose a simple encoding of charge-based quantum dot qubits which protects against fluctuating electric fields by charge symmetry. We analyse the reduction of coupling to noise due to nearby charge traps and present single qubit gates. The relative advantage of the encoding increases with lower charge trap density.
