<jats:title>Abstract</jats:title><jats:p>Quantum computing and quantum information processing (QC/QIP) crucially depend on the availability of suitable quantum bits (qubits) and methods of their manipulation. Most qubit candidates known to date are not applicable at ambient conditions. Herein, we propose radical‐grafted mesoporous silica as a versatile and prospective nanoplatform for spin‐based QC/QIP. Extremely stable Blatter‐type organic radicals are used, whose electron spin decoherence time is profoundly long even at room temperature (up to T<jats:sub>m</jats:sub>≈2.3 μs), thus allowing efficient spin manipulation by microwave pulses. The mesoporous structure of such composites is nuclear‐spin free and provides additional opportunities of embedding guest molecules into the channels. Robustness and tunability of these materials promotes them as highly promising nanoplatforms for future QC/QIP developments.</jats:p>
