Toward Manipulation of Quantum Spin Information in Biomolecules

Project manager:Assistant Professor, Institute of Multidisciplinary Research for Advanced Materials, Tohoku University Hideto Matsuoka

Recently, native photosynthetic systems have attracted much attention in the field of quantum information science because it was demonstrated that molecules involved in photosynthesis can remain entangled at room temperature. So far we have studied spin correlated radical pairs in entangled states, which are ubiquitous intermediates in photosynthesis, by high-time resolution and high-frequency EPR (Electron Paramagnetic Resonance) spectroscopy. In this work, we first stabilize quantum coherence of the radical pairs by chemical modification of photosynthetic proteins. We also focus on development of electrically detected EPR based on high-time resolution and high-frequency pulse techniques, which will be applied toward manipulating and measuring biological quantum information.
