We propose and analyze an interface between a topological qubit and a superconducting flux qubit. In our scheme, the interaction between Majorana fermions in a topological insulator is coherently controlled by a superconducting phase that depends on the quantum state of the flux qubit. A controlled-phase gate, achieved by pulsing this interaction on and off, can transfer quantum information between the topological qubit and the superconducting qubit.

Short Bio:

Liang Jiang is currently a Sherman Fairchild prize postdoctoral fellow in Theoretical Physics and working in the Institute for Quantum Information (IQI) at Caltech. He was a member of the Lukin Group in the Department of Physics at Harvard University.
His research area is quantum technology, quantum information science, and atomic molecular and optical (AMO) physics. He studies the diamond, in particular the spin coherence properties associated with the diamond color centers, which can be used to build nano-magnetometer and store quantum information. He is also interested in distributed quantum computation, topological quantum computation, and long distance quantum communication.
