The ground and excited state calculations at key geometries, such as the Frank–Condon (FC) and the conical intersection (CI)geometries, are essential for understanding photophysical properties. To compute these geometries on noisy intermediate-scalequantum devices, we proposed a strategy that combined a chemistry-inspired spin-restricted ansatz and a new excited statecalculation method called the variational quantum eigensolver under automatically-adjusted constraints (VQE/AC). Unlike theconventional excited state calculation method, called the variational quantum deflation, the VQE/AC does not require the pre-determination of constraint weights and has the potential to describe smooth potential energy surfaces. To validate this strategy,we performed the excited state calculations at the FC and CI geometries of ethylene and phenol blue at the complete active spaceself-consistent field (CASSCF) level of theory, and found that the energy errors were at most 2 kcal mol−1 even on the ibm_kawasakidevice.

日本气象厅(JMA)改进并发展了日本谱模式(JSM),使之成为业务预报模式。这个有限区域谱模式在垂直方向有十九层,水平分辨率为40km。模式的预报对象是中-α尺度的天气现象以及地形扰动的细致结构。该模式能非常好地预报天气尺度背景下的中尺度结构以及与极涡有关的中尺度云系的演变。对于梅雨季节的强降水过程,模式也非常有效。降水预报在整个春季,甚至在预报的前几小时都很理想。然而夏季的情况则远不如春季。这可能是由于模式的积云参数化方案所造成。模式系统较慢的“自加速”(spin up)也是夏季预报的一个严重问题。
