Trapped-ion quantum computer - Wikipedia
Chip ion trap for quantum computing from 2011 at NIST. A trapped-ion quantum computer is one proposed approach to a large-scale quantum computer. Ions, or charged atomic particles, can be confined and suspended in free space using electromagnetic fields.

Harvard scientists trap molecules to perform quantum operations ...
5 days ago · In these systems, tiny individual particles can be reliably trapped to serve as qubits and form quantum logic gates. The Harvard team’s paper details the far more complicated process involved with using molecules to form an iSWAP gate, a key quantum circuit that creates entanglement — the very property that makes quantum computing so powerful.

Trapped-ion quantum computing - NQCC
As well as being a relatively mature qubit architecture, ion-trap quantum computing offers several key advantages: Long coherence times and gate fidelities of more than 99% for both single-qubit and two-qubit gates.
Scalable Architecture for Trapped-Ion Quantum Computing …
Oct 21, 2024 · Here, we propose a holistic, scalable architecture for quantum computing with large ion crystals that overcomes these issues. Our method relies on dynamically operated optical potentials that instantaneously segment the ion crystal into cells of a manageable size.
Trapping the ions with electromagnetic forces in vacuum isolates them almost perfectly from their environment and thus permits extremely long storage times of the fragile quantum information (exceeding 10 minutes in some cases (Bollinger et al., 1991; Fisk et al., 1997)).
