Scalable Topological Quantum Computer

Background:

Quantum computing uses superposition and entanglement (rather than the electrical impulses used in “classical” computing) to perform calculations that cannot be achieved using classical computers. Quantum computing is based on qubits, which carry information in a quantum state. A major challenge to quantum computing is maintaining the quantum states of qubits, which are inherently fragile. To overcome this, quantum computing researchers have recently explored using particles known as Majorana fermions, which have the unique quality of being topologically protected. This allows them to maintain coherence against local perturbations. This makes Majorana fermions an attractive option in the development of quantum computers.

Technology Overview:

This technology is a conceptual framework for developing a scalable topological quantum computer. It relies on forming Majorana fermions (or zero modes) using nanoscale circular electronic gates in two-dimensional p-wave superconductors. The gates serve two purposes: (1) modulate the chemical potential locally to turn a topological superconductor into a normal conductor, and (2) move the Majorana fermions in space-time. The gates allow the precise control of the number, position, and dynamics of Majorana fermions. Using an array of such gates, it is possible to implement the full features of topological quantum computation, including the braiding and fusion of Majorana fermions in space-time.
