Parametrically Activated Entangling Gates Using Transmon Qubits
S. Caldwell, N. Didier, C. A. Ryan +59
We describe and implement a family of entangling gates activated by radio-frequency flux modulation applied to a tunable transmon that is statically coupled to a neighboring transm…
Resonant magneto-optic Kerr effect in the magnetic topological insulator Cr:(Sb,Bi)Te
Shreyas Patankar, J. P. Hinton, Joel Griesmar +10
We report measurements of the polar Kerr effect, proportional to the out-of-plane component of the magnetization, in thin films of the magnetically doped topological insulator $(\t…
Precise quantization of anomalous Hall effect near zero magnetic field
A. J. Bestwick, E. J. Fox, Xufeng Kou +3
We report a nearly ideal quantum anomalous Hall effect in a three-dimensional topological insulator thin film with ferromagnetic doping. Near zero applied magnetic field we measure…
Composite Fermions and Broken Symmetries in Graphene
F. Amet, A. J. Bestwick, J. R. Williams +4
The electronic properties of graphene are described by a Dirac Hamiltonian with a fourfold symmetry of spin and valley. This symmetry may yield novel fractional quantum Hall (FQH)…
Unconventional Josephson Effect in Hybrid Superconductor-Topological Insulator Devices
J. R. Williams, A. J. Bestwick, P. Gallagher +6
We report on transport properties of Josephson junctions in hybrid superconducting-topological insulator devices, which show two striking departures from the common Josephson junct…
Electron-nuclear interaction in 13C nanotube double quantum dots
H. O. H. Churchill, A. J. Bestwick, J. W. Harlow +5
For coherent electron spins, hyperfine coupling to nuclei in the host material can either be a dominant source of unwanted spin decoherence or, if controlled effectively, a resourc…
