Qubits in Double Quantum Well Structure

We propose a new approach to producing the qubits in electron ballistic transport in low-dimensional structures such as double quantum wells or double quantum wires. Next, we examine the possibility to produce quantum entanglement in the framework of the Jaynes-Cummings model and shown that at least in principle, the entanglement can be achieved due to series of "revivals" and "collapses" in the population inversion due to the interaction of a quantized single-mode EM-field with a two-level system.
