Among various quantum computing platforms, trapped-ion-based quantum computing stands out as one of the most promising and mature platforms, offering advantages such as long coherence times, high gate fidelity, and all-to-all connectivity between qubits.

Ion-trap-based quantum computers require electrodes to confine ions using electric potential. Both electrodes and optical components can be fabricated at the micro to nanoscale using MEMS technology.

Quantum networks are crucial for realizing secure communication and developing more powerful quantum computing devices. Scalable quantum networks can be realized through modular architecture leveraging ion-photon entanglement.

A well-designed system architecture is essential for building a full-stack quantum computer capable of executing practical quantum algorithms with high fidelity, including scheduling physical-level gate operations and error correction policies.

Quantum error correction is the key element to implement fault-tolerant quantum computers. The main focus is implementing practical quantum error correction code for near-term hardwares.

To utilize the full power of quantum computer, properly designed quantum algorithm is necessary. Research group is interested in developing algorithms which are tailored for quantum circuits.
