Quantum Algorithm for Calculating Molecular Vibronic Spectra

Description

Recently, not only academics but also industries such as Google, IBM, and Intel are interested in quantum computation research. 

 

We expect a prototype quantum computer, which can outperform classical computers in 10 years. Among the various applications of quantum computing, quantum computational chemistry would become a major application area of quantum computing. 

 

Prof. Huh has been developing quantum simulation method for molecular vibronic spectroscopy for non-universal quantum computers. 

 

In this work, an efficient quantum algorithm for the molecular vibronic spectroscopy, which can be operated in the universal quantum computer, was developed. This new quantum algorithm based on the quantum phase estimation algorithm can be applied to more complicated molecular quantum anharmonic oscillator problems.
