Ultracold ions are among the most thriving physical platforms in the field of quantum computing: the long coherence time and the high gate fidelity lead in quantum volume (221) over other systems, including the superconducting platform (whose maximum demonstrated quantum volume is 29). Ion quantum computers have allowed implementing the deepest benchmarking algorithms to date and successfully demonstrating error correction codes, which opens up the prospect of moving from the current era of noisy quantum processors (NISQ) to the next era. In Russia, the field of ion quantum computers began to actively develop with the "Quantum Computing" Roadmap launched in 2020. In this review, we present the basic principles of operation of an ion quantum computer and discuss recent achievements in this area worldwide, along with the main results of our group obtained in implementing the Roadmap.
