For the quantum coherence of electron spins in solid materials to be exploited in future technologies such as quantum computing, the problem of spin decoherence due to electron spins coupling to the noisy environment must first be solved. Here, pulsed electron paramagnetic resonance is used to demonstrate experimentally optimal dynamical decoupling for preserving electron spin coherence in irradiated malonic acid crystals at temperatures from 50 K to room temperature.
