The Video shows an electron, represented by a Gaussian wave packet (blue), that travels along a conductor connected to an asymmetric device. A magnetic field is applied perpendicular to the conducting plane. When the wave packet arrives at the device, it is partly reflected and partly transmitted.
This video shows the same situation as Video 1, except that the wave packet is approaching from the opposite direction. Here, the wave packet behaves likewise, however, the duration of reflection and transmission is different.
The video shows an electron, represented by a Gaussian wave packet (blue), that travels across an asymmetric Aharonov-Bohm ring (gold) biased with a magnetic flux. The wave packet arrives from the left and passes the ring in a straightforward manner.
This video shows the same situation as Video 3, except that the wave packet is approaching from the opposite direction. In this case, the wave packet arriving from the right passes the ring only after having been reflected back and forth.
The video shows the propagation of a wave packet in a closed system provided by two contacts and an asymmetric Aharonov-Bohm ring biased with a magnetic flux. The unitary propagation is interrupted by three collapse processes highlighted in purple which correspond to quantum measurements.
