We realize an electronic Mach-Zehnder interferometer with quantum Hall edge channels along a pn junction in graphene. Confined to a two-dimensional plane, electrons in a strong magnetic field travel along the edge in one-dimensional quantum Hall channels that are protected against backscattering. These channels can be used as solid-state analogs of monochromatic beams of light, providing a unique platform for studying electron interference. Electron interferometry is regarded as one of the most…

Quantum Hall Valley Splitters and a Tunable Mach-Zehnder Interferometer in Graphene.
The demonstration of electronic beam splitters in graphene that couple quantum Hall edge channels having opposite valley polarizations points toward universal processes driving the quantum decoherence in those two different 2D systems, with graphene being much more robust to their effect.

The conductance in the bipolar regime is strongly suppressed, indicating that copropagating edge states, even with the same spin, do not equilibrate along PN interfaces, and is attributed to the formation of an insulating ν = 0 stripe at the PN interface.
Edge mixing dynamics in graphene p–n junctions in the quantum Hall regime
Shot noise in the quantum Hall regime is finite in the bipolar regime, but is strongly suppressed in the unipolar regime, which is consistent with the theoretical prediction and gives microscopic evidence that the edge states are uniquely mixed along the p–n junction.
