Epitaxy of Advanced Nanowire Quantum Devices

Understand

Semiconductor nanowires provide an ideal platform for various low-dimensional quantum devices.

• In particular, topological phases of matter hosting non-Abelian quasi-particles can emerge when a semiconductor nanowire with strong spin-orbit coupling is brought in contact with a superconductor.
• To fully exploit the potential of non-Abelian anyons for topological quantum computing, they need to be exchanged in a well-controlled braiding operation.
• Essential hardware for braiding is a network of single-crystalline nanowires coupled to superconducting islands.
