Fabricating a Quantum Hall Interferometer Based on Marginally Twisted Graphene

Quantum Hall (QH) effect allows the exploitation of quantum coherence of electrons for various applications from metrology to quantum computation. QH interferometry is a convenient tool that provides an archetypal platform to achieve fractional QH state braiding statistics. However, a phase coherence along the length of the interferometer and suppression of Coulomb charging energy is required to observe fractional statistics.
