针对适合原子离子量子信息处理（QIP）应用的潘宁离子阱提出了许多替代设计。第一个陷阱设计是一个简单的长直线阵列，它允许容易的光学访问。这个陷阱的原型已建成陷阱Ca+和一个简单的电子检测方案已被用来演示陷阱的操作。另一种陷阱设计由一个导电板组成，导电板上有一个孔，位于连续导电平面上方。最终的陷阱设计是基于一个阵列的垫电极。虽然这种阱设计缺乏上述其他阱的开放几何形状，但垫设计可以证明在混合方案中是有用的，其中信息处理和量子位存储发生在不同类型的阱中。垫陷阱的行为进行了数值模拟和技术之间的陷阱迅速移动离子进行了讨论。这些不同的设计与未来的实验进行了讨论。所有的设计都适合于构建多个阱阵列，如可扩展离子阱QIP所需。
A number of alternative designs are presented for Penning ion traps suitable for quantum information processing (QIP) applications with atomic ions. The first trap design is a simple array of long straight wires, which allows easy optical access. A prototype of this trap has been built to trap Ca+ and a simple electronic detection scheme has been employed to demonstrate the operation of the trap. Another trap design consists of a conducting plate with a hole in it situated above a continuous conducting plane. The final trap design is based on an array of pad electrodes. Although this trap design lacks the open geometry of the other traps described above, the pad design may prove useful in a hybrid scheme in which information processing and qubit storage take place in different types of trap. The behaviour of the pad traps is simulated numerically and techniques for moving ions rapidly between traps are discussed. Future experiments with these various designs are discussed. All of the designs lend themselves to the construction of multiple trap arrays, as required for scalable ion trap QIP.
