One of the most advanced quantum computer architectures is based on individual atomic ion qubits, suspended by electric fields and individually addressed with laser beams.  This platform features reconfigurable entangling gates and dense connectivity, allowing the efficient expression of circuits, algorithms, and simulations. Moreover, trapped ion qubits possess the prerequisites for scaling (even without quantum error correction): they are nearly perfectly replicable and suffer negligible idle errors. Nearly all of the errors in an ion trap system are driven by classical controllers and are well-understood, meaning that we can continually improve the quality of quantum gates through engineering, even as more qubits are added.  I will review the state-of-art in ion trap quantum computers, and speculate on their future.
