Research Summary

Masashi Kawasaki

Trapped ion quantum computer is one of the most promising quantum hardwares with its high fidelity due to the qubits using intrinsically identical atomic ions. Not only increasing the number of qubits but also enhancing the quality of qubits are crucial for pursuing the possibility of quantum computation. In our research team, we will develop highly efficient quantum algorithms by fully utilizing the commercial trapped ion quantum computers. We will also construct trapped ion quantum computers using qubits and bosons of atomic ions for expanding the computationally viable region.
