Time-optimal transfer of the quantum state in long qubit arrays
arXiv:2501.11933 · doi:10.1103/mxrq-7rl4
Abstract
Recent technological advances have allowed the fabrication of large arrays of coupled qubits serving as prototypes of quantum processors. However, the optimal control of such systems is notoriously hard, which limits the potential of large-scale quantum systems. Here, we investigate a model problem of quantum state transfer in a large nearest-neighbor-coupled qubit array and derive an optimal control that simultaneously enables maximal fidelity and minimal time of the transfer.
