利用分子振动和旋转模式构建了基本量子门，对两个量子比特进行编码，并实现了Deutsch-Jozsa算法。选择的分子体系为12C16O。利用最优控制理论(OCT)构建了几个相位校正全局量子门。栅极保真度大于90%。结合这些基本门实现Deutsch-Jozsa算法时，保真度大于96.11%，这表明振动和旋转量子比特是执行量子算法的理想选择。
Elementary quantum gates have been constructed using molecular vibrational and rotational modes to encode two qubits and implement the Deutsch–Jozsa algorithm. The molecular system chosen was 12C16O. Several phase-correct global quantum gates were constructed using optimal control theory (OCT). The gate fidelity was more than 90%. On implementing the Deutsch–Jozsa algorithm combining these elementary gates, a fidelity greater than 96.11% was obtained, which indicates that vibrational and rotational qubits are promising for performing quantum algorithms.
