Why trapped ions?
Trapped-ion qubits offer long coherence times, high-fidelity operations, and full connectivity— serving as an ideal foundation for modular architectures that enable scalable, fault-tolerant quantum computing.
They also provide long coherence times and high gate fidelities — enabling compact systems to run algorithms with fewer error-correction overheads. Our architecture focuses on modular scaling and software-driven control.
Characteristics of Ion-Trap Qubits
Fidelity Consistency
High precision in quantum gate operations (manipulating qubit states)
⇒
Extremely low error rate variation among qubits
High Coherence
Long coherence time
⇒
Preserves quantum states for extended periods
Full Connectivity

• Drawbacks:
•Slow gate operation speed
•Difficult to expand the number of qubits
Integration of Micro-Optical Cavities and Ion Traps
Based on the research foundation pursued by Prof. Hiroki Takahashi over the past 15 years, leading the research on a "Photonically Interconnected Ion Trap Quantum Computer" as part of the QIST / Moonshot Project since 2020.
