About Trapped Ion Technology
Trapped-ion quantum computers use individual ionized atoms (typically ytterbium or barium) suspended in electromagnetic fields as qubits. Quantum information is encoded in the electronic states of the ions. Laser pulses or microwave fields implement gate operations. Ions naturally interact with each other through Coulomb repulsion, enabling all-to-all connectivity without physical wiring.
Exceptional gate fidelities (99.9%+), long coherence times (seconds to hours), and native all-to-all qubit connectivity eliminate the need for SWAP routing that limits other architectures.
Gate operations are slow (microseconds to milliseconds), limiting circuit throughput. Scaling to many ions in a single trap is difficult due to spectral crowding; modular trap architectures are being developed to address this.
