“…* In composite or hybrid systems, non-adiabatic transitions can bring a system from one state to desired state that might be entangled one (Li et al, 2011). For a system of qubits the transfer state between qubits was studied with a photonic qubit (localized exciton in an optically active quantum dot) coupled to a spin qubit hosted in gate-defined quantum dots (Joecker et al, 2019).…”

Robust Quantum Gates in Decoherence-Free Subspaces with Josephson Charge Qubits

et al. 2012

We propose a new and feasible scheme to implement quantum gates in decoherence-free subspaces (DFSs) with Josephson charge qubits situated in a circuit QED architecture. Based on the resonator-assisted interaction, the controllable interqubit couplings occur only by tuning the individual flux biases, by which we obtain the DFS-encoded universal quantum gates. Compared with the non-DFS situation, we numerically consider the robustness of the DFS-encoded scheme that can be insensitive to the collective noises. Thus the protocol may perform the fault-tolerant quantum computing with Josephson charge qubits.

“…One is reversibly transferring quantum states in a feasible way [16], which is requisite for the storage and retrieval of information. Another is how to enhance the transfer fidelity by reducing the decoherence effects [25,29,30]. To realize the perfect QST, one should combine the above two aspects to reversibly implement the robust state transfer, which is highly preferable for the scalable quantum information processing.…”
