Symmetry-protected gates of Majorana qubits in a high- superconductor platform
Matthew F. Lapa, Meng Cheng, Yuxuan Wang
We propose a platform for braiding Majorana non-Abelian anyons based on a heterostructure between a -wave high- superconductor and a quantum spin-Hall insulator. It has bee…
Quantized frequency-domain polarization of driven phases of matter
Ian Mondragon-Shem, Ivar Martin, A. Alexandradinata +1
Periodically driven quantum systems can realize novel phases of matter that do not exist in static settings. We study signatures of these drive-induced phases on the -dimens…
How quickly can anyons be braided? Or: How I learned to stop worrying about diabatic errors and love the anyon
Christina Knapp, Michael Zaletel, Dong E. Liu +3
Topological phases of matter are a potential platform for the storage and processing of quantum information with intrinsic error rates that decrease exponentially with inverse temp…
Fractional Josephson Effect in Number-Conserving Systems
Meng Cheng, Roman M. Lutchyn
We study fractional Josephson effect in a particle-number conserving system consisting of a quasi-one-dimensional superconductor coupled to a nanowire or an edge carrying fra…
Probing Majorana Physics in Quantum Dot Shot Noise Experiments
Dong E. Liu, Meng Cheng, Roman M. Lutchyn
We consider a quantum dot coupled to a topological superconductor and two normal leads and study transport properties of the system. Using Keldysh path-integral approach, we study…
Helical order in one-dimensional magnetic atom chains and possible emergence of Majorana bound states
Younghyun Kim, Meng Cheng, Bela Bauer +2
We theoretically obtain the phase diagram of localized magnetic impurity spins arranged in a one-dimensional chain on top of a one- or two-dimensional electron gas with Rashba spin…
