As part of the quantum computing ecosystem that aims to create Quantum Spain, the TalentQ program focuses on the training and growth of talent. To this end, resources will be allocated for the organization of events such as seminars, schools, workshops and hackathons, the support of local initiatives and groups, and the creation of a support infrastructure with tutorials and other utilities that allow you to progress in quantum computing.

Seminar | Benjamin Schiffer

Abstract: We propose a quantum computer architecture based on ions confined in optical tweezer arrays, combining the long coherence times of trapped-ion qubits with the reconfigurability and parallel operation enabled by tweezer platforms. Ions are transported to interaction zones, where excitation to an auxiliary state with a displaced optical potential generates a controllable effective electric dipole. We develop and analyze entangling-gate mechanisms mediated by the Coulomb interaction and outline a concrete implementation with barium ions based on state-selective polarizability. We also study the suppression of cross-talk during parallel gate execution, with relevance to transversal gates in quantum error correction.
The talk will be based on the recent preprint: https://arxiv.org/abs/2606.27249
