WKB Analysis of Tunnel Coupling in a Simple Model of a Double Quantum Dot
A simplified model of a double quantum dot is presented and analyzed, with applications to spin-qubit quantum computation. The ability to trap single electrons in semiconductor nanostructures has led to the proposal of quantum computers with spin-based qubits coupled by the exchange interaction. C...
