Quantized Majorana conductance

Understand

Majorana zero-modes hold great promise for topological quantum computing.

• Tunnelling spectroscopy in electrical transport is the primary tool to identify the presence of Majorana zero-modes, for instance as a zero-bias peak (ZBP) in differential-conductance.
• The Majorana ZBP-height is predicted to be quantized at the universal conductance value of 2e2/h at zero temperature.
• Interestingly, this quantization is a direct consequence of the famous Majorana symmetry, 'particle equals antiparticle'.
