The QTCAD (Quantum Technology Computer-Aided Design) software (a trademark (TM) registered in Canada) has been available for sale in the form of software licenses since 2022, and the market therefor is international. The technical and general information are available online in English and French on the Internet websites of the company Nanoacademic Technologies Inc. and Its affiliated partners. QTCAD (TM) enables detailed modeling of very small scale (nanoscale) elementary components of future quantum computers developed by state research businesses or groups. It enables design through prediction of the qubit properties of semi-conductor materials, all based on architectures and technologies, existing or under development, using the spin properties of eleentary or other particles, that are vectors of quantum entanglement information to create the bases for this rapidly emerging industry. QTCAD (TM) is proposed in the form of non-exclusive, non-transferable software licenses for commercial purposes with restrictive user rights and conditions, offered to different types of users: research groups in universities and public and private laboratories, in companies of all kinds, and worldwide
