Trapped Rydberg ions are a promising novel approach to quantum computing and simulations. They are envisaged to combine the exquisite control of trapped ion qubits with the fast two-qubit Rydberg gates already demonstrated in neutral atom experiments. Coherent Rydberg excitation is a key requirement for these gates. Here, we carry out the first coherent Rydberg excitation of an ion and perform a single-qubit Rydberg gate, thus demonstrating basic elements of a trapped Rydberg ion quantum computer.
被俘获的里德堡离子是一种很有前景的量子计算和模拟新方法。人们设想将被俘获离子量子比特的精确控制与中性原子实验中已展示的快速双量子比特里德堡门相结合。相干里德堡激发是这些门的关键要求。在此，我们首次对离子进行了相干里德堡激发，并执行了单量子比特里德堡门操作，从而展示了被俘获里德堡离子量子计算机的基本元件。
