Emulating Majorana Fermions Using Transmon Qubits with Application to Topological Quantum Computing

Majorana Fermions are fermionic modes with non-abelian dynamics and are of significant interest to realize topologically protected quantum processors. There have been signifcant efforts by the community to realize the Majorana modes in solid-state devices. Despite significant progress, fabricating and operating a Majorana qubit has proven to be extremely challenging.

In this talk, we propose a different approach: instead of trying to realize Majorana modes in solid-state systems such as Superconducting/Semiconducting naowires, we propose to engineer an array of transmon qubits to realize a meta material with Majorana modes. We will present an example design of such system, the chip layout, as well as discuss braiding, fusion, and readout schemes. We will also disucss intricaties and constraints associated with practical device fabrication procedures.
