Abstract
The quantum life science field was created aiming to elucidate the quantum mechanism of life together with development of new measurement technology as a study group in 2017. Q‐LEAP project was started in 2020. The three major targets of the project were (A) development of quantum sensor for life science use, (B) hyperpolarized technique for highly sensitive NRI/NMR, (C) quantum mechanism in living organism. The researches of quantum sensor are the application of diamond NV center as a super sensitive fluorescent material and in vivo sensor for temperature and pH. Hyperpolarized MRI is used for highly sensitive measurement of the metabolism. One quantum mechanism in animal is expected in magnetic compass in migrating bird. The application of AI and quantum computer are discussed in brain research. Quantum methods are also discussed in cognitive neuroscience.
