我们报告的第一个实验实现的受控非（cnot）量子门和纠缠的两个不同同位素的原子，并证明两个原子量子比特之间的串扰可以忽略不计。该实验是基于对原子的强里德伯封锁，原子被限制在两个分开的单原子光阱中。在没有任何原子损失或痕量损失修正的情况下，量子门和纠缠态的原始质量分别为和。我们的工作有应用程序的多体系统与多物种相互作用的模拟，量子计算，量子计量学。
We report on the first experimental realization of the controlled-not(cnot) quantum gate and entanglement for two individual atoms of different isotopes and demonstrate a negligible cross talk between two atom qubits. The experiment is based on a strong Rydberg blockade forandatoms confined in two single-atom optical traps separated by. The raw fidelities of thecnotgate and entanglement areand, respectively, without any corrections for atom loss or trace loss. Our work has applications for simulations of many-body systems with multispecies interactions, for quantum computing, and for quantum metrology.
