Abstract: At sufficiently low temperatures, condensed-matter systems tend to develop order. An notable exception to this behavior is quantum spin-liquids, where fluctuations prevent transition to an ...
Abstract: 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 cohe...
Abstract: One of the major obstacles in quantum information technology is to prevent a quantum bit (qubit) from dephasing, while still being able to reliably manipulate and readout the qubit. In the ...
Abstract: It has been well-known that topological phenomena with fractional excitations, i.e., the fractional quantum Hall effect (FQHE) will emerge when electrons move in Landau levels. In this talk...
Abstract: Feynman's "no-node" theorem states that the conventional many-body ground state wavefunctions of bosons in the coordinate representation are positive de nite. This implies that time-reversa...
Abstract: In this talk, I will describe several experiments demonstrating simple quantum computation primitives using multi-photon entanglement and semiconductor quantum dot spin. I will start with a...
