我们详细描述了一种用于普适量子计算的在真空中捕获和操纵任意数目的电子的理论方案。通过静电场和磁场的组合，粒子被限制在彭宁陷阱的线性阵列中。通过控制相邻粒子之间的库仑相互作用来实现双电子操作。这种设备的性能通过时钟速度、保真度和消相干率来评估。
We describe in detail a theoretical scheme to trap and manipulate an arbitrary number of electrons in vacuum for universal quantum computation. The particles are confined in a linear array of Penning traps by means of a combination of static electric and magnetic fields. Two-electron operations are realized by controlling the Coulomb interaction between neighboring particles. The performances of such a device are evaluated in terms of clock speed, fidelity, and decoherence rates.
