The ion trap technology is not only effective but also relatively straightforward, relying on basic principles of physics to manipulate atoms for quantum computing purposes. The system successfully isolates natural quantum units from the rest of the universe, allowing them to maintain delicate quantum states for extended periods and enabling high-level control and interaction between them, making them the gold standard of qubits.
