Disorder-induced crossover from phase-averaging to mode-mixing regimes in magnetic domain walls of a second-order topological insulator
Dong Zhou, Zhe Hou
We investigate electronic transport across a magnetic domain wall (DW) in a three-dimensional (3D) second-order topological insulator subject to Anderson disorder. In the clean lim…
Mediated gates between spin qubits
Jianjia Fei, Dong Zhou, Yun-Pil Shim +3
In a typical quantum circuit, nonlocal quantum gates are applied to nonproximal qubits. If the underlying physical interactions are short-range (e.g., exchange interactions between…
Cavity-assisted quantum bath engineering
K. W. Murch, U. Vool, D. Zhou +3
We demonstrate quantum bath engineering for a superconducting artificial atom coupled to a microwave cavity. By tailoring the spectrum of microwave photon shot noise in the cavity,…
Phenomenological noise model for superconducting qubits: two-state fluctuators and 1=f noise
Dong Zhou, Robert Joynt
We present a general phenomenological model for superconducting qubits subject to noise produced by two-state fluctuators whose couplings to the qubit are all roughly the same. In…
Topology of Entanglement Evolution of Two Qubits
Dong Zhou, Gia-Wei Chern, Jianjia Fei +1
The dynamics of a two-qubit system is considered with the aim of a general categorization of the different ways in which entanglement can disappear in the course of the evolution,…
Suppression of Decoherence and Disentanglement by the Exchange Interaction
Amrit De, Alex Lang, Dong Zhou +1
Entangled qubit pairs can serve as a quantum memory or as a resource for quantum communication. The utility of such pairs is measured by how long they take to disentangle or decohe…
