Since its establishment, Quemix has been a quantum software startup company from Japan that has been focusing on developing algorithms for error-tolerant quantum computers (FTQC). At Q2B 2025 Tokyo, we will be announcing an advanced use case in which we have incorporated an error detection function into our proprietary quantum chemistry calculation algorithm "PITE®" and performed practical material calculations on a current quantum computer. We look forward to welcoming everyone interested in quantum technology and quantum business.

Under rapidly changing social conditions, such as the declining birthrate, aging population, and the advancement of DX, utilization of Al is essential to realize an inclusive society. However, conventional machine learning requires more significant training data and complex learning models. Thus, computational time, power consumption, and cost of data collection are becoming severe bottlenecks. In SQAl, we advance quantum machine learning and simulation and integrate them as a quantum HPC infrastructure through quantum embedding and optimization techniques. Through the creation of sustainable quantum Al, we will realize a society in which everyone can fully utilize the latest information technology without energy concerns by implementing a "sustainable virtuous circle that generates emergence" in society.
