Boundaries, disorder and noise in quantum-coherent systems
… by the presence of boundaries, disorder, and classical noise. First, we consider surface states in Dirac materials. We show that these systems can host ballistically propagating modes that are immune, to a large extent, to disorder at boundaries. Furthermore, in contrast to the conventional …

Revisiting physics of quantum bits
… superconducting flux qubit, environmental noises that are usually recognized to only have dissipative effects and the trivial resultant dephasing, can also cause pure dephasing. Furthermore, it is demonstrated that, in the current domain of interest for quantum computation purposes, the …

Topics in quantum information theory and quantum many-body physics
… exponential separation between quantum and classical performance. For those that are, natural generalizations remain elusive. One speedup that has especially resisted generalization is the use of quantum walks to traverse the welded tree graph, due to Childs, Cleve, Deotto, Farhi, Gutmann, …

Developing Small-scale Quantum Information Processors based on Electronic Spins in Diamond
… is limited by decoherence, a practical (i.e., classical) and predictive noise model for the device is desired. As the first step to characterize the coherence of a multi-qubit register, we demonstrate a method to build a self-consistent classical noise model for individual qubits. For the NV …
