    "abstract": "We show that the U(2) group structure of thin barriers can be adopted for\nquantum information processing when used in combination with environmental\npotential whose bouncing modes are profile preserving. Qubits are realized as\nwave functions localized in either side of the barrier which divides the\none-dimensional system into two regions. It is argued that this model is a\ntheoretical prototype of a robust and scalable quantum computing device.\n  Keywords: Quantum Computation, Quantum Wire, Quantum Contact Interaction",
