Transmission and reflection of charge-density wave packets in a quantum Hall edge controlled by a metal gate

Abstract: Quantum energy teleportation (QET) is a proposed protocol related to the quantum vacuum. The edge channels in a quantum Hall system is well suited for the experimental verification of QET. For this purpose, we examine a charge density wave excited and detected by capacitively coupled front gate electrodes. We observe the waveform of the charge density wave, which is proportional to the time derivative of the applied square voltage wave. Further, we study the transmission and reflection behaviors of the charge … Show more

“…This QH edge state constitutes a 1D system that exhibits uniquely high coherence [6] and hosts a wide variety of physics [7][8][9][10][11][12][13], such as the Tomonaga-Luttinger liquid [12,13], anyonic statistics [14,15], and charge-neutral upstream Majorana modes of the edge current [7]. Furthermore, it offers the potential for exotic applications, including topological and flying qubit quantum computation [16][17][18] and quantum energy teleportation [19][20][21]. The properties of these edge states are typically examined through electric measurements [6-13, 18, 19, 22], including shot-noise [6][7][8] and heattransport measurements [9].…”
