USE CASES / 01
Analyzing the calculation of photochemistry reactions
CLIENT
Mitsubishi Chemical, JSR (Case study from QPARC)
BACKGROUND
A photochemistry reaction plays an important factor on modeling materials for artificial photosynthesis or OLEDs.
With conventional classical computers, it was difficult to calculate the “photoexcited states” with high accuracy. However, with quantum computers, this calculation can be made possible and can become a practical method with lower calculation times and high accuracy.
Experiments & Findings
Due to the state of current quantum computers not having the capacity to process industrially practical molecules, we verified the calculation of smaller related systems on simulator.
Through testing wide variety of current quantum algorithm we identified certain algorithm is able to obtain chemical accuracy and has the potential to adapt to a bigger system.
USE CASES / 02
Proposed method for calculation of periodic systems
CLIENT
Mitsubishi Chemical, Toyota Central R&D Labs., Inc., Sumitomo Metal Mining (Case study from QPARC)
BACKGROUND
The energy calculation of the periodic system is a crucial step upon manufacturing semiconductors or energy conversion. There have been numerous attempts using different calculation approaches, with some formulas currently used upon the material designing fields, however it has its limitations upon some systems such as that which involves heavy metals, which cannot be calculated with conventional classical computers.
Quantum computers has the potential of calculating larger systems, however the calculation of periodic systems require a large number of qubits.
This is the main reason why there are barely any examples with an actual application, until recently where there have been some cases applying to the periodic systems.
Experiments & Findings
Taking consideration of the limitations of the current quantum computer, we first simulated Hydrogen chain model to demonstrate Peierls transition on simulator.
This resulted in successfully identifying the Hydrogen chain causing a Peierls transition, confirming the usefulness and accuracy of the quantum algorithm for periodic systems.
There remains a challenge of reducing the large number of qubits required for periodic systems, which is a crucial step for running such as solid-state material.
