We have calculated the persistent currents and the density of states in an open metallic ring connected to an electron reservoir in the presence of a magnetic flux. As a special case, we have considered the situation wherein electrons enter and leave the ring in a sub-barrier regime characterised by evanescent modes throughout the circumference of the ring. In such a situation, the persistent current arises due to two non-classical effects, namely, Aharonov-Bohm effect and quantum tunnelling.

Unique nanoscale phenomena arise in quantum and mesoscale properties and there are additional intriguing twists from effects that are classical in origin. In this chapter, these are brought forth through an exploration of quantum computation with the important notions of superposition, entanglement, non-locality, cryptography and secure communication. The quantum mesoscale and implications of nonlocality of potential are discussed through Aharonov-Bohm effect, the quantum Hall effect in its various forms including spin, and these are unified through a topological discussion. Single electron effect as a classical phenomenon with Coulomb blockade including in multiple dot systems where charge stability diagrams may be drawn as phase diagram is discussed, and is also extended to explore the even-odd and Kondo consequences for quantum-dot transport. This brings up the self-energy discussion important to nanoscale device understanding.
