论文摘要
本质上,所有已知的量子门都依赖于弱耦合近似,导致线性动力学。通过捕获离子的明确例子,我们展示了在这种近似之外可以实现高保真量子门,并且我们得出了易于实现的驾驶场,以实现具有极高忠诚度的门,该离子在羔羊dicke策略范围之外,只能通过多普勒冷却来实现运动温度。
Essentially all known quantum gates rely on a weak-coupling approximation resulting in linear dynamics. With the explicit example of trapped ions, we show how high-fidelity quantum gates can be achieved outside such an approximation, and we derive readily implementable driving fields to realize gates with extremely high fidelities for ions well outside the Lamb-Dicke regime with motional temperatures achievable by only Doppler cooling.
