Why Are Correct Calculations Born but Not Used?

QunaSys Inc. (Headquarters: Bunkyo-ku, Tokyo; CEO: Tien-Chun Yang), which promotes the industrial application of quantum computers, will hold an online webinar on Thursday, May 14, 2026, on the theme of 'The Relationship Between Calculation and Experiment,' with Mr. Takahiro Igarashi from the Japan Atomic Energy Agency (JAEA) as a guest.

**■ Webinar Overview**

- **Event Name:** Why Are Correct Calculations Born but Not Used? —Exploring from real experience the background of why they are not utilized in experiments and how to convey the value of calculations— - **Date and Time:** May 14, 2026 (Thursday) 14:00-15:00 - **Format:** Online (Zoom) - **Participation Fee:** Free (pre-registration required) - **Organizer:** QunaSys Inc.

**■ Background and Aim of this Webinar**

In R&D settings, while the use of simulation and computational science is advancing, the following discrepancies arise between researchers who handle calculations and those who handle experiments.

- **Concerns of researchers handling calculations:** - 'They say it's unusable on-site' even though we are producing technically correct results. - We don't receive calculation requests from the experimental side in the first place. - **Concerns of researchers handling experiments:** - We don't get useful insights from the calculation results and end up relying on experiments after all. - We can't imagine that calculations can solve our problems, so we don't use them.

This situation is not the fault of one side. It is rooted in a structural gap, such as 'the value of calculation results for on-site decision-making is not being sufficiently communicated' and 'the desired objectives are not being sufficiently shared.'

In this webinar, we will welcome Mr. Igarashi from JAEA, who has been working for many years to connect calculation and experiment in research on complex phenomena such as corrosion.

**How can we transform 'correct calculations' into 'value that is useful for on-site decision-making'?**

We will unravel the identity of the 'structure of non-use,' where nobody is wrong but things don't mesh, and the concrete ways to overcome it, based on real experience.

**■ Program (Tentative)** 1. Opening Remarks / Explanation of Purpose (QunaSys) 2. Lecture by Mr. Igarashi - Why are calculations perceived as 'unusable on-site'? - What do researchers handling experiments expect from calculations? - The turning point when 'unused calculations' became 'calculations used for decision-making.' 3. Dialogue - What attitudes should researchers handling calculations and experiments change? 4. Q&A 5. Closing
