pic ・Quantum Coin Method for Numerical Integration
 We improve and implement the quantum algorithm for Monte Carlo integration (QCoin). We make sure on a simulator that the error rate of QCoin is better than the limitation of classical Monte Calro and comparable to the previous quantum algorithm (QSS). Moreover, we suggest that QCoin is a quantum-classical hybrid algorithm and fundamentally robust under the noise in actual quantum computers. We conduct numerical experiments on a quantum computer to confirm the robustness.

pic ・First principle calculation for BCS-type superconductivity of hBN-Li-hBN
 A superconducting transition temperature (Tc) up to 25 K in the Li-intercalated bilayer of hexagonal boron nitride (h-BN) is predicted according to ab-initio calculations. A Tc higher than that of metal-intercalated graphene is ascribed to the characteristic spatial distribution of electronic states near the Fermi level, which is distinctly different from graphene's. Our results provide a new design guideline for two-dimensional superconductors based on intercalated layered materials.
