Description
Summary:Magnetic molecules have shown great potential in quantum information processing due to the chemical tunablity of their quantum behaviors. Chemical derivatives of endohedral nitrogen fullerenes with long coherence time and rich energy levels were synthesized and studied to demonstrate the ability of multiprocessing in quantum information using electron magnetic resonance. After initialization of the 12‐levelled spin system, subgroups of spin energy levels coursed by the hyperfine couplings can be selectively manipulated. The cooperatively combining of the parallel calculations enabled quantum error correction, increasing the correct rate by up to 17.82 %. Also, different subgroups of transitions divided by hyperfine coupling can be treated as independent qubits, and multi‐task quantum computing were realized by performing Z‐gate and X‐gate simultaneously, which accelerates the overall gating speed. Chemical derivatives of endohedral nitrogen fullerenes with long coherence time were used to demonstrate the multiprocessing of quantum computing with different subgroups of energy transitions divided by hyperfine couplings. Cooperatively combining the parallelly calculated results enabled quantum error correction of a D‐J algorithm and multi‐task qubit manipulations of different types of quantum gates.
