Attend a seminar exploring optimal control strategies for quantum state transfer in large-scale qubit arrays. Discover how recent technological advances have enabled the fabrication of large arrays of coherently operating coupled qubits that serve as prototypes for quantum processors, while learning about the significant challenges in controlling such systems due to their extremely large number of degrees of freedom. Examine a model problem of quantum state transfer in nearest-neighbor-coupled qubit arrays and understand the optimal control strategy that simultaneously achieves maximal fidelity and minimal transfer time. Learn how this approach reaches the quantum speed limit in lattices with time-varying couplings, addressing one of the key limitations that restricts the potential of large-scale quantum systems. The presentation will be delivered by Dr. Maxim Gorlach from ITMO University and is based on recent research published in Physical Review Letters, providing insights into cutting-edge developments in quantum control theory and its applications to quantum computing architectures.
