Research

Fundamental quantum computing research and algorithm development.

About Topological Technology

Topological quantum computers aim to encode qubits in non-Abelian anyons — exotic quasiparticles whose quantum state is stored non-locally in the topology of the system rather than in individual physical degrees of freedom. Microsoft is pursuing Majorana zero modes at semiconductor-superconductor interfaces as the physical basis. In principle, topological qubits are intrinsically protected from local noise.

Key Advantage

Topological protection could dramatically reduce the error rate per physical qubit, potentially enabling fault-tolerant quantum computing with far fewer physical qubits than other approaches.

Key Challenge

The technology is still in early experimental stages. Majorana zero modes have only recently been demonstrated in simplified devices. Implementing two-qubit gates between topological qubits and scaling the architecture remain unsolved engineering challenges.
