一维接触相互作用下的量子比特实现
Locational Qubit Realization with One-dimensional Contact Interactions
摘要：
我们证明了薄势垒的U（2）群结构与环境势（其弹跳模是保形的）结合使用时，可以用于量子信息处理。量子比特被实现为位于势垒两侧的波函数，势垒将一维系统分成两个区域。有人认为，这个模型是一个强大的和可扩展的量子计算设备的理论原型。关键词：量子计算，量子线，量子接触相互作用
英文摘要：
We show that the U(2) group structure of thin barriers can be adopted for quantum information processing when used in combination with environmental potential whose bouncing modes are profile preserving. Qubits are realized as wave functions localized in either side of the barrier which divides the one-dimensional system into two regions. It is argued that this model is a theoretical prototype of a robust and scalable quantum computing device. Keywords: Quantum Computation, Quantum Wire, Quantum Contact Interaction
