Pseudomagnetic Field and Quantum Computing at Landau Levelsin Nanographite Films

Abstract

Visualization of the pseudomagnetic field in nanographite films using optical radiation from Landau levels significantly simplifies magnetic field detection compared to the proposal by the authors of who used a scanning tunneling microscope at a temperature of 7.5 K to visualize Landau levels [1-2]. In our case, optical radiation measurements from Landau levels were conducted using a photodiode at room temperature. The existence of a stable Landau level staircase in nanographite films opens the possibility of quantum computing on Landau level qubits.
