A decoherence-free subspace in a charge quadrupole qubit

Robust implementations of semiconducting qubits require overcoming the effects of charge noise, which limits coherence times. Here the authors propose a decoherence-free subspace for charge qubits to protect them from uniform electric field fluctuations, proposing an implementation in a triple quant...
