摘要：

We present a scheme for creating and measuring entanglement between two double quantum dot charge qubits in a transport setup in which voltage pulses can modify system parameters. Detection of entanglement is performed via the construction of a Bell inequality with current correlation measurements. An essential feature is the use of the internal dynamics of the qubits as the constituent electrons tunnel into the leads to give the single-particle rotations necessary for the Bell measurement.
