Fast high-fidelity multi-qubit state transfer with long-range interactions
arXiv:2009.06587 · doi:10.1103/PhysRevA.103.042425
Abstract
We describe an efficient protocol to perform quantum state transfer using Hamiltonian dynamics with long-range interactions. The time to transfer qubits a sufficiently large distance is proportional to . Even without error correction, the fidelity of this multi-qubit state transfer process remains finite for arbitrarily well-separated qubits in the presence of uncorrelated random errors in coupling constants.
