A method for calculating ground-state electron density using orbital-free density functional theory (OF-DFT) with Quemix's fault-tolerant quantum computing algorithm "PITEⓇ" was proposed.

Large-scale numerical simulations require significant computational resources. Quemix is advancing the development of quantum circuits for fluid simulations using its proprietary PITEⓇ method. Quantum advantage has been demonstrated in linear advection-diffusion equations, and further research will focus on solving nonlinear reaction-diffusion systems and large-scale fluid dynamics problems.

Exploring innovations in diffusion models with channel attention in QNN and explaining the potential of quantum computing for image generation.

TerraSkyDay is held every year by TerraSky Co., Ltd., the parent company of Quemix.

We introduced and explained the differences between quantum computers and classical computers, our technologies such as PITE®️, and what quantum computers can bring to humanity.

With the growing momentum in quantum computing research in recent years, CCP2023 included research findings related to the development of quantum computer algorithms, presented through both oral and poster sessions. I gave an oral presentation titled "Quantum Algorithm for Optimal Molecular Geometries Based on Probabilistic Imaginary-Time Evolution."

We have investigated a large-scale simulation of L10 FePt nanoparticles toward magnetic recording. The critical diameter for long term storage is estimated based on first-principles calculations.

In our group, we have proposed the imaginary time evolution method as a non-variational approach for calculating the ground state in many-body problems. In this study, we constructed a quantum algorithm for structural optimization of molecules based on the first quantized Hamiltonian using the imaginary time evolution method. In the proposed framework, atomic nuclei are treated as classical point charges, while electrons are treated as quantum-mechanical particles.

Due to the exponential decay feature of high-energy states, quantum algorithms based on the imaginary time evolution (ITE) method have been actively studied.　 We propose a probabilistic way to realize the action of the ITE operator by introducing auxiliary qubits.　　This is called the probabilistic ITE (PITE) method.

The key to effective use of quantum computers is how to reduce the effects of quantum noise and produce reliable computational results. 

In this R&D, we constructed a quantum error reduction method using a group of noise effect quantum circuits, a group of quantum circuits that represent quantum noise effects, the source of quantum computation errors

Quantum computation algorithms for obtaining the ground state of a given Hamiltonian are in strong demand, for example in quantum chemical calculations and optimization.  In this study, we propose a new ground-state computation framework based on the imaginary-time evolution method for error-tolerant quantum gated computers.

Skyrmions can appear in non-centrosymmetric materials due to non-vanishing Dzyaloshinskii–Moriya interactions (DMIs). We investigate the magnetic properties of rhombohedral MX3 (M: V, Cr, Mn, Fe; X: Cl, Br, I) with van der Waals materials with centrosymmetric lattices.
