The ν = 5/2 quantum Hall state is conjectured to be a Moore‐Read state. According to that, quasiparticles carry a charge of e/4 and obey a “non‐abelian” statistics. Previous measurements of the tunneling quasiparticles charge (across a quantum point contact), via shot‐noise measurements [1], were indeed consistent with the charge of the quasiparticles being e/4, and were inconsistent with other potentially possible values, such as e/2 and e. The large scattering of the experimental data in these measurements made the precise determination of the quasi‐particle charge hard to achieve. Here we present new and improved shot noise data, which provide an even more conclusive evidence for the tunneling of e/4 quasiparticles at the ν = 5/2 state. |
